ST. PETERSBURG, Fla. (AP) — Stinging jellyfish, rays with their whip-like tails and sharks on the hunt are some ocean hazards that might typically worry beachgoers. But rip currents are the greatest danger and account for the most beach rescues every year.
About 100 people drown from rip currents along U.S. beaches each year, according to the United States Lifesaving Association. And more than 80 percent of beach rescues annually involve rip currents.
The National Weather Service lists 16 known deaths so far in 2024 from rip currents in U.S. waters, including the Florida fatalities as well as eight deaths in Puerto Rico and two in Texas.
Here are some things to know about rip currents:
What is a rip current?
Rip currents are narrow columns of water flowing rapidly away from the beach, like a swift stream within the ocean. They don’t pull swimmers under water, but can carry them out a fair distance from shore.
Low spots along the beach, or areas near jetties or piers, are often where rip currents form. They can be connected to stormy weather but also sometimes occur during sunny days. They can be hard to detect because the surface water often appears calm.
The current can flow as swiftly as eight feet per second (3.2 meters per second), faster than even a strong swimmer can overcome, according to the National Oceanic and Atmospheric Administration.
“If you’re caught in one and you try to swim straight in, you’re not going to be able to,” said Daniel Barnickel of Palm Beach County Ocean Rescue.
How can someone escape a rip current?
The most frequent advice from beach rescue teams and weather forecasters is to not panic and look for a chance to swim parallel to the shore until the swimmer is out of the rip current’s grip. It will eventually dissipate but might leave the swimmer out in deeper water.
It’s nearly impossible to fight the current directly. Many swimmers who get in trouble tire themselves out trying to get back to the beach, lifeguards say. If possible, it’s best to swim near a lifeguard station.
“Most of our rip current rescues happen outside the guarded areas because we’re not there to prevent it from happening,” Barnickel said.
What warning systems exist for rip currents?
Flags with different colors are used to warn beachgoers of various hazards.
Three flags warn of surf and rip current conditions. Red means a high hazard, yellow means a moderate threat and green means low danger. There’s also purple for dangerous sea life, like jellyfish, and double red when a beach is closed for any reason.
The National Weather Service posts rip current risks on its websites around the coasts and has developed a computer model that can predict when conditions are favorable for their formation up to six days in advance for the U.S. East and Gulf Coasts, Puerto Rico, Hawaii and Guam.
“Before this, forecasters were manually predicting rip currents on a large section of the ocean twice a day and only a day or two into the future. The earlier prediction has potential to substantially increase awareness and reduce drownings,” said Gregory Dusek, a NOAA scientist who developed the model, in a post on the agency’s website.
High risk warnings were posted for most Florida beaches last week, when the drownings occurred.
Should someone attempt a rip current rescue?
It can be dangerous to try to rescue someone caught in a rip current, officials say. Often the people trying to perform the rescue can get into trouble themselves.
It’s best to find a lifeguard, if there is one, or call 911 if a struggling swimmer is spotted. People on shore can also try to tell the person to swim parallel to shore.
“Never swim alone. And always make sure that there’s an adult. And make sure that you don’t overestimate your abilities. Know your limits,” Barnickel said.

Grim Irony: Curbing Air Pollution Is Warming the Earth Faster
Frank Landymore – June 25, 2024
Cool Factor
Have industrial emissions been counteracting the worst effects of global warming? Scientists are starting to think so.
Burning coal, oil, and gas warms our planet by dispersing greenhouse gases, like CO2, into the atmosphere. And before the introduction of more stringent environmental regulations, these fuel sources would often contain deadly pollutants like sulfur oxide that contribute to the deaths of millions of people globally.
World governments have rightly fought to curb pollutants. But as a growing body evidence is beginning to show, these airborne particles, or aerosols, have likely mitigated rising temperatures by reflecting sunlight and boosting the reflectivity of clouds — and as a result, concealed just how bad global warming actually is.
The extent of the cooling they’ve caused is more contentious. Nonetheless, it’s a grim irony that exemplifies the complexities of understanding — nevermind protecting — our climate.
“We’re starting from an area of deep, deep uncertainty,” Zeke Hausfather, a climate scientist from the University of California, Berkeley, told The Washington Post. “It could be a full degree of cooling being masked.”
Abandon Ship
One of the biggest drop-offs in pollutants may come from the shipping industry, whose regulatory body in 2020 started limiting the use of the dirty, sulfur-spewing fuels its massive vessels once relied on, in favor of cleaner alternatives.
But with the resulting decrease in aerosols, recent research has shown that these cuts in shipping pollution has directly led to more solar radiation being trapped in our atmosphere, which could explain why 2023 was the hottest year on record by a margin that alarmed even scientists.
That doesn’t augur well for the future: the authors of the research suggested that as we curb these deadly pollutants, we could experience double the rate of global warming compared to the average since 1880.
As WaPo notes, however, many experts think the warming will be less pronounced, contributing somewhere between 0.05 degrees and 0.1 degrees Celsius of an uptick — which, of course, is still significantly worrying.
Clear the Air
There is, perhaps, a silver lining. The same cooling principle of these pollutants could be wielded in an experimental technique called marine cloud brightening, which would involve deliberately injecting safe aerosols into the atmosphere to cause clouds to reflect more sunlight and to increase cloud cover.
This is unproven and controversial, though, and the researchers behind the shipping study have suggested that their findings are an example of the downsides of pursuing that technique: the minute we stop pumping aerosols into the atmosphere, global temperatures will soar again, perhaps even more drastically than before.
At any rate, clarifying these gray areas will be paramount for climate scientists. The picture is more complicated than we once thought, and determining how much aerosols figure into it will be essential if humanity is to keep global warming short of even more disastrous levels.
“It’s not just a story of greenhouse gas emissions,” Robert Wood, a professor of atmospheric science at the University of Washington, told WaPo. “Whether you clean up rapidly, or whether you just fumble along with the same aerosol emissions, could be the difference of whether you cross the 2-degree Celsius threshold or not.”
We’ve been accidentally cooling the planet — and it’s about to stop

It is widely accepted that humans have been heating up the planet for over a century by burning coal, oil and gas. Earth has already warmed by almost 1.2 degrees Celsius (2.2 degrees Fahrenheit) since preindustrial times, and the planet is poised to race past the hoped-for limit of 1.5 degrees Celsius of warming.
But fewer people know that burning fossil fuels doesn’t just cause global warming – it also causes global cooling. It is one of the great ironies of climate change that air pollution, which has killed tens of millions, has also curbed some of the worst effects of a warming planet.
Tiny particles from the combustion of coal, oil and gas can reflect sunlight and spur the formation of clouds, shading the planet from the sun’s rays. Since the 1980s, those particles have offset between 40 and 80 percent of the warming caused by greenhouse gases.
And now, as society cleans up pollution, that cooling effect is waning. New regulations have cut the amount of sulfur aerosols from global shipping traffic across the oceans; China, fighting its own air pollution problem, has slashed sulfur pollution dramatically in the last decade.
The result is even warmer temperatures – but exactly how much warmer is still under debate. The answer will have lasting impacts on humanity’s ability to meet its climate goals.
“We’re starting from an area of deep, deep uncertainty,” said Zeke Hausfather, a climate scientist and research lead for the payments company Stripe. “It could be a full degree of cooling being masked.”
Most of the cooling from air pollution comes through sulfur aerosols, in two ways. The particles themselves are reflective, bouncing the sun’s rays away and shading the Earth. They also make existing clouds brighter and more mirror-like, thus cooling the Earth.
Coal and oil are around 1 to 2 percent sulfur – and when humans burn fossil fuels, that sulfur spills into the atmosphere. It is deadly: Sulfur dioxide has been linked to respiratory problems and other chronic diseases, and air pollution contributes to about 1 in 10 deaths worldwide.
Over the past few decades, countries have worked to phase out these pollutants, starting with the United States and the European Union, followed by China and India. China has cut its sulfur dioxide emissions by over 70 percent since 2005 by installing new technologies and scrubbers on fossil fuel plants. More recently, the International Maritime Organization instituted restrictions in 2020 on the amount of sulfur allowed in shipping fuels – one of the dirtiest fuels used in transportation. Shipping emissions of sulfur dioxide immediately dropped by about 80 percent. Mediterranean countries are planning a similar shipping regulation for 2025.
“There has been a pretty steep decline over the last 10 years,” said Duncan Watson-Parris, an assistant professor at the Scripps Institution of Oceanography at the University of California at San Diego.
These moves have saved lives – according to estimates, around 200,000 premature deaths have already been avoided in China, and the new shipping regulations could save around 50,000 lives per year. But they have also boosted global temperatures. Scientists estimate that the changes in aerosols from the new shipping rule alone could contribute between 0.05 and 0.2 degrees Celsius of warming over the next few decades.
Some researchers have suggested that the changes to ocean shipping regulations may have been a big contributor to last year’s record heat – and that aerosols may have been masking much more heat than previously thought. Satellite images have shown that cloud changes declined after sulfur emissions went down.
“The data from NASA satellites shows that in regions where this should be expected, there’s a very strong increase in absorbed solar radiation,” said Leon Simons, an independent researcher and a member of the Club of Rome of the Netherlands, pointing to shipping areas affected by the new rules. “And also in this period you see sea surface temperatures increasing in the same region.”
In one new paper, scientists at the University of Maryland argued that the decrease in aerosols could double the rate of warming in the 2020s, compared to the rate since 1980. But other researchers have critiqued their results.
Many experts believe the effect is likely to be modest – between 0.05 and 0.1 degrees Celsius. “I don’t think it’s possible to get better than a factor of two, in terms of how uncertain we are,” said Michael Diamond, a professor of meteorology and environmental science at Florida State University.
Some scientists see the shipping regulation as an analog to a way that researchers are exploring to halt global warming: purposefully brightening clouds using less polluting methods. In Alameda, Calif., researchers recently released sea salt aerosols into the atmosphere as a first step to study how the particles could brighten clouds and reflect sunlight. City officials later halted the project, despite reports showing that the experiment was safe.
But the real issue is still ahead. Currently, the U.N. Intergovernmental Panel on Climate Change estimates that aerosols are masking about 0.5 degrees Celsius of global warming. But that value could be as high as 1 degree or as low as 0.2 degrees – and the difference could be the difference between meeting the goals of the 2015 Paris agreement or not.
If aerosols have been masking cooling much more than expected, for example, the world could be poised to blow past its climate targets without realizing it.
Almost 200 of the world’s nations pledged in the Paris agreement to keep warming below 2 degrees Celsius (3.6 degrees Fahrenheit), compared to preindustrial levels. Scientists believe that many dangerous impacts, from the collapse of coral reefs to the melting of major ice sheets, will occur somewhere between 1.5 and 2 degrees Celsius.
“It’s not just a story of greenhouse gas emissions,” said Robert Wood, a professor of atmospheric science at the University of Washington. “Whether you clean up rapidly, or whether you just fumble along with the same aerosol emissions, could be the difference of whether you cross the 2-degree Celsius threshold or not.”
No scientists are advocating a halt to aerosol clean up efforts – the death tolls from air pollution are simply too high. “There are really good reasons to want to be cleaning up air pollution,” Diamond said. “The public health benefits are really important.”
But researchers worry that cleaning up air pollution without halting fossil fuel use – as, for example, in China – could be a recipe for even greater and faster warming. “We need to make sure that we’re doing it at the same time as cleaning up methane and cleaning up CO2,” Diamond said. Cutting methane emissions, he noted, could help offset the effects of declining aerosols. Methane has a warming effect, but like aerosols, doesn’t remain in the atmosphere for very long.
Still, a lot of scientific questions remain – and until they are answered, the world won’t know exactly how much warming falling aerosols will unmask.

“America is back.” In the early days of his presidency, Joe Biden repeated those words as a starting point for his foreign policy. The phrase offered a bumper-sticker slogan to pivot away from Donald Trump’s chaotic leadership. It also suggested that the United States could reclaim its self-conception as a virtuous hegemon, that it could make the rules-based international order great again. Yet even though a return to competent normalcy was in order, the Biden administration’s mindset of restoration has occasionally struggled against the currents of our disordered times. An updated conception of U.S. leadership—one tailored to a world that has moved on from American primacy and the eccentricities of American politics—is necessary to minimize enormous risks and pursue new opportunities.
To be sure, Biden’s initial pledge was a balm to many after Trump’s presidency ended in the dual catastrophes of COVID-19 and the January 6 insurrection. Yet two challenges largely beyond the Biden administration’s control shadowed the message of superpower restoration. First was the specter of Trump’s return. Allies watched nervously as the former president maintained his grip on the Republican Party and Washington remained mired in dysfunction. Autocratic adversaries, most notably Russian President Vladimir Putin, bet on Washington’s lack of staying power. New multilateral agreements akin to the Iran nuclear deal, the Paris agreement on climate change, or the Trans-Pacific Partnership were impossible, given the vertiginous swings in U.S. foreign policy.
Second, the old rules-based international order doesn’t really exist anymore. Sure, the laws, structures, and summits remain in place. But core institutions such as the UN Security Council and the World Trade Organization are tied in knots by disagreements among their members. Russia is committed to disrupting U.S.-fortified norms. China is committed to building its own alternative order. On trade and industrial policy, even Washington is moving away from core tenets of post–Cold War globalization. Regional powers such as Brazil, India, Turkey, and the Gulf states pick and choose which partner to plug into depending on the issue. Even the high-water mark for multilateral action in the Biden years—support for Ukraine in its fight against Russia—remains a largely Western initiative. As the old order unravels, these overlapping blocs are competing over what will replace it.
A Biden victory in this fall’s election would offer reassurance that the particular risk of another Trump presidency has passed, but that will not vanquish the forces of disorder. To date, Washington has failed to do the necessary audit of the ways its post–Cold War foreign policy discredited U.S. leadership. The “war on terror” emboldened autocrats, misallocated resources, fueled a global migration crisis, and contributed to an arc of instability from South Asia through North Africa. The free-market prescriptions of the so-called Washington consensus ended in a financial crisis that opened the door to populists railing against out-of-touch elites. The overuse of sanctions led to increased workarounds and global fatigue with Washington’s weaponization of the dollar’s dominance. Over the last two decades, American lectures on democracy have increasingly been tuned out.
Indeed, after Hamas’s October 7 attack on Israel and the Israeli military campaign in Gaza, American rhetoric about the rules-based international order has been seen around the world on a split screen of hypocrisy, as Washington has supplied the Israeli government with weapons used to bombard Palestinian civilians with impunity. The war has created a policy challenge for an administration that criticizes Russia for the same indiscriminate tactics that Israel has used in Gaza, a political challenge for a Democratic Party with core constituencies who don’t understand why the president has supported a far-right government that ignores the United States’ advice, and a moral crisis for a country whose foreign policy purports to be driven by universal values. Put simply: Gaza should shock Washington out of the muscle memory that guides too many of its actions.
If Biden does win a second term, he should use it to build on those of his policies that have accounted for shifting global realities, while pivoting away from the political considerations, maximalism, and Western-centric view that have caused his administration to make some of the same mistakes as its predecessors. The stakes are high. Whoever is president in the coming years will have to avoid global war, respond to the escalating climate crisis, and grapple with the rise of new technologies such as artificial intelligence. Meeting the moment requires abandoning a mindset of American primacy and recognizing that the world will be a turbulent place for years to come. Above all, it requires building a bridge to the future—not the past.
THE TRUMP THREAT
One of Biden’s mantras is “Don’t compare me to the Almighty; compare me to the alternative.” As the presidential campaign heats up, it is worth heeding this advice. But to properly outline the dangers of a second Trump term, it is necessary to take Trump’s arguments seriously, despite the unserious form they often take. Much of what Trump says resonates broadly. Americans are tired of wars; indeed, his takeover of the Republican Party would have been impossible without the Iraq war, which discredited the GOP establishment. Americans also no longer trust their elites. Although Trump’s rhetoric about a “deep state” moves quickly into baseless conspiracy theory, it strikes a chord with voters who wonder why so many of the politicians who promised victories in Afghanistan and Iraq were never held to account. And although Trump’s willingness to cut off assistance to Ukraine is abhorrent to many, there is a potent populism to it. How long will the United States spend tens of billions of dollars helping a country whose stated aim—the recapture of all Ukrainian territory—seems unachievable?
Trump has also harnessed a populist backlash to globalization from both the right and the left. Particularly since the 2008 financial crisis, large swaths of the public in democracies have simmered with discontent over widening inequality, deindustrialization, and a perceived loss of control and lack of meaning. It is no wonder that the exemplars of post–Cold War globalization—free trade agreements, the U.S.-Chinese relationship, and the instruments of international economic cooperation itself—have become ripe targets for Trump. When Trump’s more punitive approaches to rivals, such as his trade war with China, didn’t precipitate all the calamities that some had predicted, his taboo-breaking approach appeared to be validated. The United States, it turned out, did have leverage.
But offering a potent critique of problems should not be confused with having the right solutions to them. To begin with, Trump’s own presidency seeded much of the chaos that Biden has faced. Time and again, Trump pursued politically motivated shortcuts that made things worse. To end the war in Afghanistan, he cut a deal with the Taliban over the heads of the Afghan people, setting a timeline for withdrawal that was shorter than the one Biden eventually adopted. Trump pulled out of the Iran nuclear deal despite Iranian compliance, unshackling the country’s nuclear program, escalating a proxy war across the Middle East, and sowing doubt across the world about whether the United States keeps its word. By moving the U.S. embassy in Israel from Tel Aviv to Jerusalem, recognizing the annexation of the Golan Heights, and pursuing the Abraham Accords, he cut the Palestinians out of Arab-Israeli normalization and emboldened Israel’s far right, lighting a fuse that detonated in the current war.
Although Trump’s tougher line with China demonstrated the United States’ leverage, it was episodic and uncoordinated with allies. As a result, Beijing was able to cast itself as a more predictable partner to much of the world, while the supply chain disruptions caused by trade disputes and decoupling created new inefficiencies—and drove up costs—in the global economy. Trump’s lurch from confronting to embracing Kim Jong Un enabled the North Korean leader to advance his nuclear and missile programs under reduced pressure. Closer to home, Trump’s recognition of an alternative Venezuelan government under the opposition leader Juan Guaidó managed to strengthen the incumbent Nicolás Maduro’s hold on power. The “maximum pressure” policy toward Venezuela and Cuba, which sought to promote regime change through crippling sanctions and diplomatic isolation, fueled humanitarian crises that have sent hundreds of thousands of people to the United States’ southern border.

A second Trump term would start amid a more volatile global environment than his first, and there would be fewer guardrails constraining a president who would be in command of his party, surrounded by loyalists, and freed from ever having to face voters again. Although there are many risks, three stand out. First, Trump’s blend of strongman nationalism and isolationism could create a permission structure for aggression. A withdrawal of U.S. support for Ukraine—and, perhaps, for NATO itself—would embolden Putin to push deeper into the country. Were Washington to abandon its European allies and promote right-wing nationalism, it could exacerbate political fissures within Europe, emboldening Russian-aligned nationalists in such places as Hungary and Serbia who have echoed Putin in seeking to reunite ethnic populations in neighboring states.
Despite U.S.-Chinese tensions, East Asia has avoided the outright conflict of Europe and the Middle East. But consider the opportunity that a Trump victory would present to North Korea. Fortified by increased Russian technological assistance, Kim could ratchet up military provocations on the Korean Peninsula, believing that he has a friend in the White House. Meanwhile, according to U.S. assessments, China’s military will be ready for an invasion of Taiwan by 2027. If Chinese leader Xi Jinping truly wishes to forcibly bring Taiwan under Beijing’s sovereignty, the twilight of a Trump presidency—by which point the United States would likely be alienated from its traditional allies—could present an opening.
Second, if given the chance, Trump has made it clear that he would almost certainly roll back American democracy, a move that would reverberate globally. If his first election represented a one-off disruption to the democratic world, his second would more definitively validate an international trend toward ethnonationalism and authoritarian populism. Momentum could swing further in the direction of far-right parties in Europe, performative populists in the Americas, and nepotistic and transactional corruption in Asia and Africa. Consider for a moment the aging roster of strongmen who will likely still be leading other powers—not just Xi and Putin but also Narendra Modi in India, Benjamin Netanyahu in Israel, Ali Khamenei in Iran, and Recep Tayyip Erdogan in Turkey. To say the least, this cast of characters is unlikely to promote respect for democratic norms within borders or conciliation beyond them.
This leads to the third danger. In the coming years, leaders will increasingly be confronted with global problems that can be managed or solved only through cooperation. As the climate crisis worsens, a Trump presidency would make a coordinated international response much harder and validate the backlash against environmental policies that has been building within advanced economies. At the same time, artificial intelligence is poised to take off, creating both valuable opportunities and enormous risks. At a moment when the United States should be turning to diplomacy to avoid wars, establish new norms, and promote greater international cooperation, the country would be led by an “America first” strongman.
A TIME TO HEAL
In any administration, national security policy is a peculiar mix of long-standing commitments, old political interests, new presidential initiatives, and improvised responses to sudden crises. Navigating the rough currents of the world, the Biden administration has often seemed to embody the contradictions of this dynamic, with one foot in the past, yearning nostalgically for American primacy, and one foot in the future, adjusting to the emerging world as it is.
Through its affirmative agenda, the administration has reacted well to changing realities. Biden linked domestic and foreign policy through his legislative agenda. The CHIPS Act made substantial investments in science and innovation, including the domestic manufacturing of semiconductors. The act worked in parallel with ramped-up export and investment controls on China’s high-tech sector, which have buttressed the United States’ lead in the development of new technologies such as AI and quantum computing. Although this story is more complicated to tell than one about a tariff-based trade war, Biden’s policy is in fact more coherent: revitalize U.S. innovation and advanced manufacturing, disentangle critical supply chains from China, and maintain a lead for U.S. companies in developing new and potentially transformative technologies.
Gaza should shock Washington out of the muscle memory that guides too many of its actions.
Biden’s most significant piece of legislation, the Inflation Reduction Act, made enormous investments in clean energy technology. These investments will allow the United States to raise its ambition in meeting climate goals by pushing domestic industry and global markets to shift away from fossil fuels faster. Although this breakthrough enhanced U.S. credibility on climate change, it also created new challenges, as even allies have complained that Washington resorted to subsidies instead of pursuing coordinated cross-border approaches to reduce emissions. In this respect, however, the Biden administration was dealing with the world as it is. Congress cannot pass complex reforms such as putting a price on carbon; what it can do is pass large spending bills that invest in the United States.
Despite tensions over U.S. industrial policy, the Biden administration has effectively reinvested in alliances that frayed under Trump. That effort has tacitly acknowledged that the world now features competing blocs, which makes it harder for the United States to pursue major initiatives by working through large international institutions or with other members of the great-power club. Instead, Washington has prioritized groupings of like-minded countries that are, to use a catch phrase, “fit for purpose.” Collaboration with the United Kingdom and Australia on nuclear submarine technology. New infrastructure and AI initiatives through the G-7. Structured efforts to create more consultation among U.S. allies in the Indo-Pacific. This approach involves a dizzying number of parts; one can lose track of the number of regional consultative groups that now exist. But in the context of an unraveled international order, it makes sense to thread together cooperation where possible, while trying to turn new habits of cooperation into enduring arrangements.
Most notably, Biden’s reinvestment in European alliances paid off when Washington was able to swiftly mobilize support for Ukraine in 2022. This task was made easier by the administration’s innovative release of intelligence on Russia’s intentions to invade, an overdue reform of the way that Washington manages information. Although the war has reached a tenuous stalemate, the effort to fortify transatlantic institutions continues to advance. NATO has grown in size, relevance, and resourcing. European Union institutions have taken a more proactive role in foreign policy, most notably in coordinating support for Ukraine and accelerating its candidacy for EU membership. For all the understandable consternation about Washington’s struggle to pass a recent aid bill for Ukraine, Europe’s focus on its own institutions and capabilities was long overdue.
SLOW TO CHANGE
Yet there are three important ways in which the Biden administration has yet to recalibrate its approach to the world of post-American primacy. The first has to do with American politics. On several issues that engender controversy in Congress, the administration has constrained or distorted its options by preemptively deferring to outdated hard-liners. Even as Trump has demonstrated how the left-right axis has been scrambled on foreign policy, Biden at times feels trapped in the national security politics of the immediate post-9/11 era. Yet what once allowed a politician to appear tough to appease hawks in Washington was rarely good policy; now, it is no longer necessarily good politics.
In Latin America, the Biden administration was slow to pivot away from Trump’s “maximum pressure” campaigns on Venezuela and Cuba. Biden maintained, for example, the avalanche of sanctions that Trump imposed on Cuba, including the cynical return of that country to the State Department’s list of state sponsors of terrorism just before leaving office, in January 2021. The result has been an acute humanitarian crisis in which U.S. sanctions exacerbated shortages of basic staples such as food and fuel, contributing to widespread suffering and migration. In the Middle East, the administration failed to move swiftly to reenter the politically contested Iran nuclear deal, opting instead to pursue what Biden called a “longer and stronger” agreement, even though Trump was the one who violated the deal’s terms. Instead,the administration embraced Trump’s Abraham Accords as central to its Middle East policy while reverting to confrontation with Iran. This effectively embraced Netanyahu’s preferred course: a shift away from pursuing a two-state solution to the Israeli-Palestinian conflict and toward an open-ended proxy war with Tehran.
Anyone who has worked at the nexus of U.S. politics and national security knows that avoiding friction with anti-Cuban and pro-Israeli hard-liners in Congress can feel like the path of least resistance. But that logic has turned into a trap. After October 7, Biden decided to pursue a strategy of fully embracing Netanyahu—insisting (for a time) that any criticism would be issued in private and that U.S. military assistance would not be conditioned on the actions of the Israeli government. This engendered immediate goodwill in Israel, but it preemptively eliminated U.S. leverage. It also overlooked the far-right nature of Netanyahu’s governing coalition, which offered warning signs about the indiscriminate way in which it planned to prosecute its military campaign, as Israeli officials cut off food and water flowing into Gaza within days of Hamas’s attack. In the months that followed, the administration has been trying to catch up to a deteriorating situation, evolving from a strategy of embracing Netanyahu, to one of issuing rhetorical demands that were largely ignored, to one of partial restrictions on offensive military assistance. Ironically, by being mindful of the political risks of breaking with Netanyahu, Biden invited greater political risks from within the Democratic coalition and around the world.
The temptation to succumb to Washington’s outdated instincts has contributed to a second liability: the pursuit of maximalist objectives. The administration has shown some prudence in this area. Even as competition ramped up with China, Biden has worked over the last year to rebuild lines of communication with Beijing and has largely avoided provocative pronouncements on Taiwan. And even as he committed the United States to helping Ukraine defend itself, Biden set the objective of avoiding a direct war between the United States and Russia (although his rhetoric did drift into endorsing regime change in Moscow). The bigger challenge has at times come from outside the administration, as some supporters of Ukraine indulged in a premature triumphalism that raised impossible expectations for last year’s Ukrainian counteroffensive. Paradoxically, this impulse ended up hurting Ukraine: when the campaign inevitably came up short, it made the broader U.S. policy toward Ukraine look like a failure. Sustaining support for Ukraine will require greater transparency about what is achievable in the near term and an openness to negotiations in the medium term.

Gaza also showcases the danger of maximalist aims. Israel’s stated objective of destroying Hamas has never been achievable. Since Hamas would never announce its own surrender, pursuing this goal would require a perpetual Israeli occupation of Gaza or the mass displacement of its people. That outcome may be what some Israeli officials really want, as evidenced by right-wing ministers’ own statements. It is certainly what many people around the world, horrified by the campaign in Gaza, believe the Israeli government really wants. These critics wonder why Washington would support such a campaign, even as its own rhetoric opposes it. Instead of seeking to moderate Israel’s unsustainable course, Washington needs to use its leverage to press for negotiated agreements, Palestinian state building, and a conception of Israeli security that is not beholden to expansionism or permanent occupation.
Indeed, too many prescriptions sound good in Washington but fail to account for simple realities. Even with the United States’ military advantage, China will develop advanced technologies and maintain its claim over Taiwan. Even with sustained U.S. support, Ukraine will have to live next to a large, nationalist, nuclear-armed Russia. Even with its military dominance, Israel cannot eliminate the Palestinian demand for self-determination. If Washington allows foreign policy to be driven by zero-sum maximalist demands, it risks a choice between open-ended conflict and embarrassment.
This leads to the third way in which Washington must change its approach. Too often, the United States has appeared unable or unwilling to see itself through the eyes of most of the world’s population, particularly people in the global South who feel that the international order is not designed for their benefit. The Biden administration has made laudable efforts to change this perception—for instance, delivering COVID-19 vaccines across the developing world, mediating conflicts from Ethiopia to Sudan, and sending food aid to places hit hard by shortages exacerbated by the war in Ukraine. Yet the overuse of sanctions, along with the prioritization of Ukraine and other U.S. geopolitical interests, misreads the room. To build better ties with developing countries, Washington needs to consistently prioritize the issues they care about: investment, technology, and clean energy.
Once again, Gaza interacts with this challenge. To be blunt: for much of the world, it appears that Washington doesn’t value the lives of Palestinian children as much as it values the lives of Israelis or Ukrainians. Unconditional military aid to Israel, questioning the Palestinian death toll, vetoing cease-fire resolutions at the UN Security Council, and criticizing investigations into alleged Israeli war crimes may all feel like autopilot in Washington—but that’s precisely the problem. Much of the world now hears U.S. rhetoric about human rights and the rule of law as cynical rather than aspirational, particularly when it fails to wrestle with double standards. Total consistency is unattainable in foreign policy. But by listening and responding to more diverse voices from around the world, Washington could begin to build a reservoir of goodwill.
A FAREWELL TO PRIMACY
In its more affirmative agenda, the Biden administration is repositioning the United States for a changing world by focusing on the resilience of its own democracy and economy while rebooting alliances in Europe and Asia. To extend that regeneration into something more global and lasting, it should abandon the pursuit of primacy while embracing an agenda that can resonate with more of the world’s governments and people.
As was the case in the Cold War, the most important foreign policy achievement will simply be avoiding World War III. Washington must recognize that all three fault lines of global conflict today—Russia-Ukraine, Iran-Israel, and China-Taiwan—run across territories just beyond the reach of U.S. treaty obligations. In other words, these are not areas where the American people have been prepared to go to war directly. With little public support and no legal obligation to do that, Washington should not count on bluffing or military buildups alone to resolve these issues; instead, it will have to focus relentlessly on diplomacy, buttressed by reassurance to frontline partners that there are alternative pathways to achieving security.
Avoiding friction with anti-Cuban and pro-Israeli hard-liners in Congress can feel like the path of least resistance.
In Ukraine, the United States and Europe should focus on protecting and investing in the territory controlled by the Ukrainian government—drawing Ukraine into European institutions, sustaining its economy, and fortifying it for lengthy negotiations with Moscow so that time works in Kyiv’s favor. In the Middle East, Washington should join with Arab and European partners to work directly with Palestinians on the development of new leadership and toward the recognition of a Palestinian state, while supporting Israel’s security. Regional de-escalation with Iran should, as it did during the Obama administration, begin with negotiated restrictions on its nuclear program. In Taiwan, the United States should try to preserve the status quo by investing in Taiwanese military capabilities while avoiding saber rattling, by structuring engagement with Beijing to avoid miscalculation, and by mobilizing international support for a negotiated, peaceful resolution to Taiwan’s status.
Hawks will inevitably attack diplomacy on each of these issues with tired charges of appeasement, but consider the alternative of seeking the total defeat of Russia, regime change in Iran, and Taiwanese independence. Can Washington, or the world, risk a drift into global conflagration? Moreover, the reality is that sanctions and military aid alone will not stop war from spreading or somehow cause the governments of Russia, Iran, and China to collapse. Better outcomes, including within those countries, will be more attainable if Washington takes a longer view. Ultimately, the health of the United States’ own political model and society is a more powerful force for change than purely punitive measures. Indeed, one lesson that is lost on today’s hawks is that the civil rights movement did far more to win the Cold War than the war in Vietnam did.
None of this will be easy, and success is not preordained, since unreliable adversaries also have agency. But given the stakes, it is worth exploring how a world of competing superpower blocs could be knitted into coexistence and negotiation on issues that cannot be dealt with in isolation. For instance, AI presents one area in which nascent dialogue between Washington and Beijing should evolve into the pursuit of shared international norms. Laudable U.S. efforts to pursue collaborative research on AI safety with like-minded countries will inevitably have to expand to further include China in higher-level and more consequential talks. These efforts should seek agreement on the mitigation of extreme harms, from the use of AI in developing nuclear and biological weapons to the arrival of artificial general intelligence, an advanced form of AI that risks surpassing human capacities and controls. At the same time,as AI moves out into the world, the United States can use its leadership to work with countries that are eager to harness the technology for positive ends, particularly in the developing world. The United States could offer incentives for countries to cooperate with Washington on both AI safety and affirmative uses of new technologies.

A similar dynamic is required on clean energy. If there is a second Biden administration, most of its efforts to combat climate change will likely shift from domestic action to international cooperation, particularly if there is divided government in Washington. As the United States works to secure supply chains for critical minerals used for clean energy, it will need to avoid constantly working at cross-purposes with Beijing. At the same time, it has an opportunity—through “de-risking” supply chains, forging public-private partnerships, and starting multilateral initiatives—to invest more in parts of Africa, Latin America, and Southeast Asia that have not always been an attractive destination for American capital. In a sense, the Inflation Reduction Act has to be globalized.
Finally, the United States should focus its support for democracy on the health of existing open societies and offering lifelines to besieged civil society groups around the world. As someone who has made the case for putting support for democracy at the center of U.S. foreign policy, I must acknowledge that the calcification of the democratic recession in much of the world requires Washington to recalibrate. Instead of framing the battle between democracy and autocracy as a confrontation with a handful of geopolitical adversaries, policymakers in democracies must recognize that it is first and foremost a clash of values that must be won within their own societies. From that self-corrective vantage point, the United States should methodically invest in the building blocks of democratic ecosystems: anticorruption and accountability initiatives, independent journalism, civil society, digital literacy campaigns, and counter-disinformation efforts. The willingness to share sensitive information, on display in the run-up to war in Ukraine, should be applied to other cases where human rights can be defended through transparency. Outside government, democratic movements and political parties across the world should become more invested in one another’s success, mirroring what the far right has done over the last decade by sharing best practices, holding regular meetings, and forming transnational coalitions.
Ultimately, the most important thing that America can do in the world is detoxify its own democracy, which is the main reason a Trump victory would be so dangerous. In the United States, as elsewhere, people are craving a renewed sense of belonging, meaning, and solidarity. These are not concepts that usually find their way into foreign policy discussions, but if officials do not take that longing seriously, they risk fueling the brand of nationalism that leads to autocracy and conflict. The simple and repeated affirmation that all human life matters equally, and that people everywhere are entitled to live with dignity, should be America’s basic proposition to the world—a story it must commit to in word and deed.

Workers Shouldn’t Have to Risk Their Lives in Heat Waves
By Terri Gerstein– June 21, 2024

Ms. Gerstein is the director of the Labor Initiative at the Robert F. Wagner Graduate School of Public Service at New York University. She spent more than 17 years enforcing labor laws in New York State, working in the state attorney general’s office and as a deputy labor commissioner.
But if you pick fruit in a field, walk door to door delivering packages, stack boxes in an oppressively hot warehouse or do any number of other jobs without air-conditioning, you don’t have much legal protection against working under sweltering conditions. In 2022 alone, 43 people died from exposure to extreme heat while working, according to the U.S. Bureau of Labor Statistics. Last year, there were others, including a postal worker who died of heat stroke in Dallas, and at least one farmworker who died after falling ill while working in extreme heat in Florida. From fields to warehouses to restaurants, laborers are in danger of illness, injuries and even death in this heat wave.
Climate scientists warn that we are reaching a tipping point where the mounting harms of global warming, including more frequent, more severe heat waves, will become irreversible. The federal government is trying to address the fact that climate change is making working conditions more dangerous each year. But its efforts aren’t likely to bear fruit quickly enough.
The key elements for protecting workers from heat above 80 degrees Fahrenheit are simple: ensure adequate rest, shade and water and allow people to adjust gradually to higher temperatures. Additional precautions are needed above 90 or 95 degrees Fahrenheit. But this is not the law in most of the country.
The Occupational Safety and Health Act has a “general duty clause” requiring employers to provide safe workplaces, but it lacks specificity on what to do in extreme heat. The Occupational Safety and Health Administration may issue a proposed rule on workplace heat relatively soon that would be likely to require, among other things, rest breaks, drinking water and cooling measures, as well as medical treatment and emergency response procedures. But once issued, there will be a comment and review period, followed by inevitable challenges from business groups arguing that the rule is too burdensome.
The Supreme Court majority’s tendency to rule against workers and overturn workplace regulation is likely to embolden these groups to appeal any decisions not in their favor, causing even more delays and perhaps thwarting the rule altogether. So it’s unlikely that any federal heat standard would take effect for the next few summers, and perhaps even longer.
There are still ways to protect workers from the heat. States could pass and enforce laws requiring employers to take simple measures to keep workers safe during deadly heat waves. Five states — Washington, Minnesota, California, Oregon and Colorado — have already passed such measures, establishing important legal and ethical norms for employers. Additional states — New York, New Jersey and Massachusetts — are considering heat protection legislation. More states should follow suit; if Minnesota thinks it’s necessary to protect its workers from heat, steamier states like Georgia and Arizona should, too.
Most states’ legislative sessions are over, limiting the possibilities for this summer, but lawmakers can prepare now and address this issue as a first order of business next year. A quicker option involves passing emergency temporary regulations through state agencies like safety and health boards. Some state and local laws may become obsolete when and if an OSHA heat rule eventually takes effect, but in the meantime they will save lives.
Cities and other local governments can act, too, passing their own workplace heat protections. Phoenix recently enacted a local heat ordinance for city contractors’ outdoor employees. Unfortunately, this option is not available in certain states, most notably Texas and Florida. After Austin, Dallas and San Antonio passed modest heat ordinances in 2023 requiring employers to give outdoor construction workers regular water breaks, Gov. Greg Abbott supported and signed a barbaric law prohibiting local action on a wide range of matters, including workplace heat. Gov. Ron DeSantis followed suit this year in Florida. (A state court ruled the Texas pre-emption law unconstitutional last year, but it’s in effect while an appeal is pending.)
Government at all levels can educate the public about these issues, and model good practices by adopting heat safety policies for their own employees. Such actions can have a big impact: Well-intentioned employers may not know what preventive steps they should take; workers may not know what to ask for; and few members of the general public know the signs of heat exhaustion or stroke. The cities of Los Angeles and Phoenix and Miami-Dade County have appointed chief heat officers who can take on some of the work of educating residents about workplace heat.
Employers, for their part, should take the initiative to learn what’s needed in their workplaces and implement those measures. And advocates, consumers and activist shareholders can also pressure corporations or industries to act.
Unions and worker advocates are now regularly pressing for heat protections as part of their focus on occupational safety and health. The Teamsters won air-conditioning in trucks as well as other heat protections in their most recent collective bargaining agreement. The National Council for Occupational Safety and Health is training workers to fight for protections. The Fair Food Program, a partnership among farmers, farmworkers and retail food companies that ensures better wages and working conditions, has among the strictest heat standards in the country for farmworkers.
In the face of the heat this week, and what’s sure to come this summer and beyond, a varied approach across different levels of government and society is the only realistic path for the immediate future. Every worker should come home safe at the end of the day, even on the hottest day of the year.
A changing climate, a changing world
Climate change around the world: In “Postcards From a World on Fire,” 193 stories from individual countries show how climate change is reshaping reality everywhere, from dying coral reefs in Fiji to disappearing oases in Morocco and far, far beyond.
The role of our leaders: Writing at the end of 2020, Al Gore, the 45th vice president of the United States, found reasons for optimism in the Biden presidency, a feeling perhaps borne out by the passing of major climate legislation. That doesn’t mean there haven’t been criticisms. For example, Charles Harvey and Kurt House argue that subsidies for climate capture technology will ultimately be a waste.
The worst climate risks, mapped: In this feature, select a country, and we’ll break down the climate hazards it faces. In the case of America, our maps, developed with experts, show where extreme heat is causing the most deaths.

Extreme heat kills hundreds, millions more sweltering worldwide as summer begins
Gloria Dickie – June 20, 2024
LONDON (Reuters) -Deadly heatwaves are scorching cities on four continents as the Northern Hemisphere marks the first day of summer, a sign that climate change may again help to fuel record-breaking heat that could surpass last summer as the warmest in 2,000 years.
Record temperatures in recent days are suspected to have caused hundreds, if not thousands, of deaths across Asia and Europe.
In Saudi Arabia, nearly two million Muslim pilgrims are finishing the haj at the Grand Mosque in Mecca this week. But hundreds have died during the journey amid temperatures above 51 degrees Celsius (124 degrees Fahrenheit), according to reports from foreign authorities.
Egyptian medical and security sources told Reuters on Thursday that at least 530 Egyptians had died while participating – up from 307 reported as of yesterday. Another 40 remain missing.
Countries around the Mediterranean have also endured another week of blistering high temperatures that have contributed to forest fires from Portugal to Greece and along the northern coast of Africa in Algeria, according to the U.S. National Oceanic and Atmospheric Administration’s Earth Observatory.
In Serbia, meteorologists forecast temperatures of around 40 C (104 F) this week as winds from North Africa propelled a hot front across the Balkans. Health authorities declared a red weather alert and advised people not to venture outdoors.
Belgrade’s emergency service said its doctors intervened 109 times overnight to treat people with heart and chronic health conditions.
In neighbouring Montenegro, where health authorities also warned people to stay in the shade until late afternoon, tens of thousands of tourists sought refreshment on the beaches along its Adriatic coast.
Europe this year has been contending with a spate of dead and missing tourists amid dangerous heat. A 55-year-old American was found dead on the Greek island of Mathraki, police said on Monday – the third such tourist death in a week.
A broad swath of the eastern U.S. was also wilting for a fourth consecutive day under a heat dome, a phenomenon that occurs when a strong, high-pressure system traps hot air over a region, preventing cool air from getting in and causing ground temperatures to remain high.
New York City opened emergency cooling centres in libraries, senior centers and other facilities. While the city’s schools were operating normally, a number of districts in the surrounding suburbs sent students home early to avoid the heat.
Meteorological authorities also issued an excessive heat warning for parts of the U.S. state of Arizona, including Phoenix, on Thursday, with temperatures expected to reach 45.5 C (114 F).
In the nearby state of New Mexico, a pair of fast-moving wildfires abetted by the blistering heat have killed two people, burned more than 23,000 acres and destroyed 500 homes, according to authorities. Heavy rains could help temper the blazes, but thunderstorms on Thursday were also causing flash flooding and complicating firefighting efforts.
All told, nearly 100 million Americans were under extreme heat advisories, watches and warnings on Thursday, according to the federal government’s National Integrated Heat Health Information System.
The brutal temperatures should begin easing in New England on Friday, the weather service said, but New York and the mid-Atlantic states will continue to endure near-record heat into the weekend.
COUNTING THE DEAD
India’s summer period lasts from March to May, when monsoons begin slowly sweeping across the country and breaking the heat.
But New Delhi on Wednesday registered its warmest night in at least 55 years, with India’s Safdarjung Observatory reporting a temperature of 35.2 C (95.4 F) at 1 a.m.
Temperatures normally drop at night, but scientists say climate change is causing nighttime temperatures to rise. In many parts of the world, nights are warming faster than days, according to a 2020 study by the University of Exeter.
New Delhi has clocked 38 consecutive days with maximum temperatures at or above 40 C (104 F) since May 14, according to weather department data.
An official at the Indian health ministry said on Wednesday there were more than 40,000 suspected heatstroke cases and at least 110 confirmed deaths between March 1 and June 18, when northwest and eastern India recorded twice the usual number of heatwave days in one of the country’s longest such spells.
Gaining accurate death tolls from heatwaves, however, is difficult. Most health authorities do not attribute deaths to heat, but rather the illnesses exacerbated by high temperatures, such as cardiovascular issues. Authorities therefore undercount heat-related deaths by a significant margin – typically overlooking thousands if not tens of thousands of deaths.
RECORD WARM TEMPERATURES
The heatwaves are occurring against a backdrop of 12 consecutive months that have ranked as the warmest on record in year-on-year comparisons, according to the European Union’s climate change monitoring service.
The World Meteorological Organization says there is an 86% percent chance that one of the next five years will eclipse 2023 to become the warmest on record.
While overall global temperatures have risen by nearly 1.3 C (2.3 F) above pre-industrial levels, climate change is fuelling more extreme temperature peaks – making heatwaves more common, more intense and longer-lasting.
On average globally, a heatwave that would have occurred once in 10 years in the pre-industrial climate will now occur 2.8 times over 10 years, and it will be 1.2 C warmer, according to an international team of scientists with the World Weather Attribution (WWA) group.
Scientists say heatwaves will continue to intensify if the world continues to unleash climate-warming emissions from the burning of fossil fuels.
If the world hits 2 C (3.6 F) of global warming, heatwaves would on average occur 5.6 times in 10 years and be 2.6 C (4.7 F) hotter, according to the WWA.

What is a heat dome? Is SC in a heat dome? What to know about ‘ring of fire’ thunderstorms.
Nina Tran, Greenville News – June 20, 2024
A heat wave is a period of unusually high temperatures over a region. As temperatures cook on the Midwest and Northeastern coast, the term “heat dome” has been used to describe the hot weather, leaving many questions to be answered.
High temperatures are forecast to reach the mid 90s Saturday through Monday, with heat indices expected to reach 100 to 104 degrees. Those who are sensitive to the heat will want to decrease their time spent outdoors to prevent heat-related illnesses.
Here’s what to know about the heat dome and how you and your family can stay safe in it.
What is a heat dome?
Per AccuWeather, the term “heat dome” is used to describe a sprawling area of high pressure promoting hot and dry conditions for days or weeks at a time. It is similar to a balloon in the way it expands and contracts as the day goes on. When a certain area is inside it, it can feel very warm. A heat dome can interfere with the production of clouds, leading to an increase in sunlight and high temperatures. In turn, the cooling demand will increase, which may boost the strain on a region’s power grid. Drought conditions may also develop due to extended dry and hot spells.
Since heat domes act as large, immovable bubbles, moisture is forced up and over the heat bubble, according to AccuWeather. This causes “ring of fire” thunderstorms to form along the fringes of heat, which may bring severe weather into the area.
“Let’s say, for example, you had a big high pressure over the Southern Plains, Texas, or Oklahoma. What will happen is, on the northern fringes of higher pressure, you’ll get these periods of thunderstorms that develop, maybe over the Central Plains. It will move around the periphery of that high pressure, which tends to be in kind of a circular shape, hence the ring terminology to it.” said Thomas Winesett with the NWS at Greenville-Spartanburg International Airport.
Ring of fire features are currently favorable for the Midwest and parts of the Ohio Valley due to centered high pressure activity in both areas. As the heat dome ensues, will South Carolina also get a chance for severe weather?
“That’s not to say we can’t get some thunderstorms, but it won’t be the true ring of fire type storms maybe until later, later next week if that high pressure shifts back off to the west or Texas, New Mexico.” Winesett said. “So when that happens, that might allow us to get into a more active pattern where we see those ring of fire type storms maybe coming more out of the Mississippi Valley and Tennessee Valley and towards the Appalachia.”

When will the heat dome end?
Doug Outlaw with the NWS at GSP said he hopes current weather conditions do not stick around for too much longer, especially with the reestablishment of high temperatures next weekend. Next Friday’s heat will bump down a few degrees before temperatures continue to soar. The timing of a cool down period remains uncertain.
“It is typical to have heat waves on and off during the summer, but we hope that the weather doesn’t get stuck and we end up way up in the 90s every day for weeks,” he said. “But we’ve got to be prepared for the possibility of something like that.”
Outlaw forecast the following high temperatures for Greenville heading into next week:
∎ Friday, June 21: 91 degrees
∎ Saturday, June 22: 93 degrees
∎ Sunday, June 23: 94 degrees
∎ Monday, June 24: 95 degrees
∎ Tuesday, June 25: 95 degrees
∎ Wednesday, June 26: 96 degrees
∎ Thursday, June 27: 95 degrees

Types of heat warnings issued by the National Weather Service
The NWS issues several types of heat advisories depending on severity. The different types are as follows:
∎ Excessive heat warning: This warning is issued 12 hours of the onset of extremely dangerous heat conditions. When the maximum heat index temperature is expected to reach 105 or higher for at least two days and the nighttime temperature will not drop below 75, the warning is issued. This rule may vary across the country, especially for areas not used to extreme heat conditions. Precautions should be taken immediately during extreme conditions to prevent serious illness and even death.
∎ Excessive heat watch: A watch is issued when an excessive heat event is favorable within the next 24 to 72 hours. When the risk of a heat wave has increased but the occurrence and timing is uncertain, a watch is issued.
∎ Heat advisory: An advisory is issued within 12 hours of the onset of extremely dangerous heat conditions. When the maximum heat index temperature is anticipated to be 100 degrees or higher for at least two days and the nighttime temperature will not drop below 75 degrees, an advisory is issued. This rule may vary across the country, especially for areas not used to extreme heat conditions. Precautions should be taken immediately during extreme conditions to prevent serious illness and even death.
∎ Excessive heat outlook: An outlook is issued when there is a potential risk for an excessive heat event within the next 3-7 days, providing information for those who need considerable lead-time to prepare for the event.

High temperatures forecast across US Midwest, Northeast
These are the high temperatures forecast for several Midwest and Northeast cities from Juneteenth and June 20. Temperatures will dip between this week and early next week, according to a USA TODAY story:
∎ Manchester, New Hampshire: 97, 99. Dropping to 86 by June 24.
∎ Albany, New York: 96, 97. Dropping to 86 by June 24.
∎ Detroit, Michigan: 95, 93. Dropping to 83 by June 24.
∎ Toledo, Ohio: 94, 96. Dropping to 84 by June 24.
∎ Indianapolis, Indiana: 92, 95. Jumping to 96 by Saturday, June 22 before dropping to 97 on June 24.
∎ Caribou, Maine: 96, 95. Dropping to 76 by June 24.
∎ Philadelphia, Pennsylvania: 94, 95. Jumping to 100 by Friday, June 21 before dropping to 90 on June 24.
∎ Boston, Massachusetts: 95, 97. Dropping to 85 by June 24.
∎ Washington, D.C.: 90, 92. Jumping to 98 by Saturday June 22 before dropping slightly to 93 on June 24.

How to prepare for the heat
Tips from NOAA:
∎ Make sure the air conditioner is functioning properly. If your home does not have air conditioning or loses power, visit a designated cooling shelter or other air-conditioned location such as the mall or public library.
∎ Check on friends, families, neighbors, and pets to ensure they are safe in the heat. It is important to check on those who live alone or do not have air conditioning.
∎ Never leave children, dependents, or pets unattended in vehicles. The sun can heat the inside of the car to deadly temperatures in minutes.
∎ Wear loose clothing that is light-colored and covers the skin.
∎ Hydrate with water throughout the day, avoiding caffeine and sugary beverages.
∎ Set aside one gallon of drinking water per person a day in case of a power outage.
∎ Keep out of the sun and stay indoors on the lowest level. Curtains and shades should be closed.
∎ Immerse yourself in a cool bath or shower. Cooling your feet off in water can also help.
∎ If temperatures are cool at night, let the cool air in by opening windows.
∎ If you are outside, stay in the shade. Apply sunblock and wear a wide-brimmed hat before going outside.
∎ To avoid heat exhaustion, do not engage in strenuous activities. Use a buddy system and take breaks in the shade when working in extreme heat.
∎ For critical updates from the National Weather Service (NWS), tune into NOAA Weather Radio.
Why this week’s heat wave could be next summer’s normal
Zack Budryk – June 20, 2024
The extreme heat slamming the eastern U.S. this week may be a sign of things to come as monthly temperature records continue to give way.
A broad swath of the Midwest and eastern U.S. are currently under a heat dome, caused by a high-pressure system in the Earth’s upper atmosphere that compresses the air beneath it, making it expand into a dome shape.
Research published in March in the journal Science Advances found that since 1979, as climate change has intensified, heat waves have gotten hotter and more commonplace, and the physical area covered by heat domes has expanded as well. They’ve also slowed down by about 20 percent, leaving the people in their paths to contend with their effects longer.
“Every summer we get heat waves, and heat waves are getting more extreme and they’re getting more frequent and they’re lasting longer,” said Jonathan Overpeck, the Samuel A. Graham dean of the School for Environment and Sustainability at the University of Michigan.
In this specific heatwave, the system of warmth is moving north and east, but it’s part of a broader, more ominous pattern in which heat waves start from a warmer background, said Richard Rood, professor emeritus of climate and space science and engineering at the University of Michigan.
“The oceans have been extraordinarily warm all year, the Atlantic and Gulf of Mexico in particular,” he said. “So when summer comes and you start seeing heat waves, you’re starting from a higher temperature background.”
As heat accumulates, Rood told The Hill, one consequence is higher temperatures earlier in the year, such as this week’s heat, which began before the official start of the summer Thursday but in earlier years might be more typical of July or August.
The extreme heat patterns began in the Midwest earlier this week, and are expected to extend into the Northeast over the rest of the week. More than 76 million people were under some form of heat advisory Tuesday morning in the U.S., and about twice that number faced temperatures of more than 90 degrees. The National Weather Service projects record-breaking heat in cities like Detroit and Philadelphia as well as parts of New England this week.
Much like the heat waves of previous years in places like Europe and the Pacific Northwest, the heat is hitting regions that have little experience with such extremes, like northern New England. This means in many cases individuals are unprepared, as is broader community infrastructure of the kind that exists in historically hotter regions.
Both personal air conditioning and resources like cooling centers are “still inadequate in a lot of areas in the U.S. where access to air conditioning hasn’t been historically needed,” said Amy Bailey, director of climate resilience and sustainability at the Center for Climate and Energy Solutions.
“Our infrastructure, our institutions and daily practices aren’t well-suited for these long stretches of extreme heat, and the longer it takes us to catch up the more lives are on the line,” Bailey added.
It also demonstrates “the criticality of having a grid that is resistant to extreme weather,” she added.
Overpeck said much of the extreme heat is attributable to the impact of climate change, but El Niño has also been a factor, and “we expect — hope might be a better word — that temperatures might start to ameliorate.”
The most recent El Niño, a climate phenomenon that causes unusually warm surface temperatures in the Pacific Ocean, began last June, which was also the warmest June on record.
The globe saw its overall hottest summer on record the same year and recently concluded a 12-month period in which every month set a temperature record.
“We’re really looking at the next few months to tell us whether something dramatic is surprising us in the global temperatures,” Overpeck said. “If it starts cooling off, [and] it hasn’t started to do that yet, we can ascribe [these] more unusual temperatures to the El Niño. If it keeps rocketing up, we’ll have to think about why climate change [is] accelerating.”
He noted that surface warming of oceans, where the majority of the heat trapped by greenhouse gases goes, has also accelerated lately.
While local authorities have urged people in affected areas to stay inside where possible, that is not an option for those who work outdoors or the homeless population of major metropolitan areas, Overpeck noted.
The temperatures of this week are likely to subside somewhat while remaining high throughout the summer, but ultimately they may be a vision of what summers look like in the longer term, Rood said. This week is almost certainly not a “one-off event,” he added. “We are probably going to see a series of events this summer.”
“I wouldn’t call it a new normal — I would call it perhaps a vision of 10, 20, 30 years,” he said. If the trend continues, he added, the extremes of this week won’t seem extraordinary years from now.
“You’re getting a glimpse into the future, warmer world,” he said.
Why some scientists think extreme heat could be the reason people keep disappearing in Greece
Laura Paddison, CNN – June 19, 2024
It was a shock when Michael Mosley, a doctor and well-known TV presenter in the UK, was found dead earlier this month after hiking in scorching temperatures on the Greek island of Symi.
But it is now one of a series of tourist deaths and disappearances in Greece as the country endures a powerful, early summer heat wave with temperatures pushing above 40 degrees Celsius (104 degrees Fahrenheit).
On Saturday, a Dutch tourist was found dead on the island of Samos. The following day, the body of an American tourist was found on Mathraki, a small island west of Corfu. Albert Calibet, another American tourist, has been missing since he set out for a hike on June 11 on Amorgos. And two French women disappeared on Sikinos after going for a walk.
The bodies of those who died still need to be examined to establish the precise cause of death, but authorities are warning people not to underestimate the impacts of the searing temperatures.
“There is a common pattern,” Petros Vassilakis, the police spokesman for the Southern Aegean, told Reuters, “they all went for a hike amid high temperatures.”
Some scientists say what’s happening in Greece offers a warning sign about the impacts of extreme heat on the body, and in particular the brain, potentially causing confusion, affecting people’s decision-making abilities and even their perception of risk.
As climate change fuels longer and more severe heat waves, scientists are trying to unravel how our brains will cope.
The brain is ‘the master switch’
Research has traditionally focused on the impact of extreme heat on muscles, skin, the lungs and the heart, but “the brain, for me, is the key to it all,” said Damian Bailey, a physiology and biochemistry professor at the University of South Wales. It’s the “master switch” for the body, he told CNN.
It’s in the brain that body temperature is regulated. The hypothalamus, a small diamond-shape structure, acts as a thermostat. It performs a delicate dance to keep the body’s internal temperature at or very close to 37 degrees Celsius (98.6 Fahrenheit). When it’s hot, the hypothalamus activates the sweat glands and widens blood vessels to cool the body down.
But the brain functions well within a narrow range of temperatures and even small changes can affect it. Many people will be familiar with a feeling of slowness and laziness on a warm summer’s day.
But as heat increases, it can have serious effects, including lowering the fluids in the body and decreasing blood flow to the brain, Bailey said. He compares the brain to a Hummer — it needs vast resources to function.
Tests he has run on research participants in an environmental chamber, where he cranked temperatures up from 21 to 40 degrees Celsius (around 70 to 104 Fahrenheit), showed a drop in blood flow to the brain by about 9% to 10%.
“That is a big deal in terms of not getting enough fuel into an engine which is running at high end all of the time,” Bailey said.

And it has an impact. Extreme heat can disrupt typical brain activity, said Kim Meidenbauer, a neuroscientist at Washington State University. The brain networks that usually allow people to think clearly, to reason, to remember, and to construct and formulate ideas, can get “thrown out of whack,” she told CNN.
It gets harder to make complex decisions, such as which path to take on a hike — a decision that sounds simple but requires weighing multiple different factors.
There’s also evidence to suggest people are more likely to make risky decisions and engage in impulsive behavior when they’re exposed to heat, she added.
An altered perception of risk coupled with impaired cognitive function can have very serious consequences. “You’re not just talking about potentially getting a little bit too warm and maybe having a sunburn,” she said. “You’re talking about potentially life-threatening (situations), like making poor decisions, having your judgement clouded.”
Scientists are only just beginning to unravel the range of impacts heat has on the brain, not just in terms of decision-making but mood, emotions and mental health.
“Our understanding is really pretty minimal,” Meidenbauer said. “It’s a major unknown at this point.”
Who is vulnerable?
Some people are more vulnerable to heat than others. Older people, especially those over 65, are more at risk, because their bodies don’t always thermoregulate as well. The people who have gone missing in Greece were all in their mid-50s and older.
Very young children and pregnant women also face elevated risk, as do those with pre-existing conditions, including mental health conditions.
But heat can be dangerous for anyone.
In 2016, a team of scientists followed 44 college students during a heat wave in Boston and found those without air conditioning experienced significant declines in cognitive performance.
“No one is immune to the health effects of heat,” said Jose Guillermo Cedeño Laurent, one of the research authors and an assistant professor at the Rutgers School of Public Health. “Our brain is an exquisitely sensitive organ,” he said.
Someone who is very fit understands the dangers and carries plenty of water is still gambling if they decide to go on a hike in very high temperatures, Bailey said.
“You make wrong decisions and it can cost you your life.”
How to protect yourself
There are behavioral things people can do to protect themselves and lower risk, experts say.
These include not exercising during the hottest parts of the day, instead going in the coolest parts of the day and seeking shade when possible. Wearing loose clothing and applying ice packs to the head and neck can also help.
Drinking water is vital and not just when you feel very thirsty, Bailey said. It’s important not to get to a point where the body is losing fluids faster than it can take them on. Experts also recommend electrolyte drinks, which can help replace some of the fluids lost through sweating.

Use location-sharing apps, said Meidenbauer. “Make sure someone knows where you are.”
Over the long term, regular exercise is important — providing it’s not outside during the hottest parts of the day — as it can help the body thermoregulate. “The fitter you are the more resilient you are to these climatic environmental stresses,” Bailey said.
It will take time to unravel the exact causes of death of those who lost their lives in Greece but there is a lesson that can still be taken away from the tragedies, Bailey said.
“No matter how intelligent or how fit you might think you are … if you’re going out in 40 degrees celsius plus temperatures, even if you’re well prepared, you’re running the gauntlet.”

Earth’s rotating inner core is starting to slow down — and it could alter the length of our days

The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth’s days — though the effects would likely be imperceptible to us.
Earth’s inner core is a roughly moon-size chunk of solid iron and nickel that lies more than 3,000 miles (4,800 kilometers) below our feet. It is surrounded by the outer core — a superhot layer of molten metals similar to those in the inner core — which is surrounded by a more solid sea of molten rock, known as the mantle, and the crust. Although the entire planet rotates, the inner core can spin at a slightly different speed as the mantle and crust due to the viscosity of the outer core.
Since scientists started mapping Earth’s inner layers with detailed seismic activity records around 40 years ago, the inner core has rotated slightly faster than the mantle and the crust. But in a new study, published June 12 in the journal Nature, researchers found that since 2010, the inner core has been slowing down and is now rotating a bit more slowly than our planet’s outer layers.
“When I first saw the seismograms that hinted at this change, I was stumped,” John Vidale, a seismologist at the University of Southern California, Dornsife, said in a statement. “But when we found two dozen more observations signaling the same pattern, the result was inescapable.”
If the inner core’s rotation continues to decelerate, its gravitational pull could eventually cause the outer layers of our planet to spin a little more slowly, altering the length of our days the researchers wrote.
However, any potential change would be on the order of thousandths of a second, which would be “very hard to notice,” Vidale said. As a result, we would likely not have to change our clocks or calendars to adjust for this difference, especially if it were only a temporary change.

This is not the first time scientists have suggested that Earth’s inner core is slowing down. This phenomenon, known as “backtracking,” has been debated for around a decade but has been very hard to prove.
In the new study, researchers analyzed data from more than 100 repeating earthquakes — seismic events that occur repeatedly at the same location — along a tectonic plate boundary in the South Sandwich Islands in the South Atlantic Ocean between 1991 and 2023.
Each earthquake allowed scientists to map the core’s position relative to the mantle and by comparing these measurements, the team was able to see how the inner core’s rotation rate changed over time.
The new study is the “most convincing” evidence so far that backtracking has been happening, Vidale said.
It is currently unclear why the inner core is backtracking, but it is likely caused by either “the churning of the liquid iron outer core that surrounds it” or “gravitational tugs from the dense regions of the overlying rocky mantle,” the researchers wrote.
It is also unclear how frequent backtracking is. It is possible that the inner core’s spin is constantly accelerating and decelerating, but these changes likely happen over decades or longer. Therefore, longer data sets are needed to infer anything about long-term trends.
