An Iranian professional soccer player has been sentenced to death after protesting against the death of Mahsa Amini, according to Iran Wire.
Amir Nasr-Azadani, 26, was arrested in November in relation to the killing of a police colonel and two volunteer militia members.
He has been accused of “waging war against God” and will be hanged, according to Iran Wire.
FIFPRO, the international soccer players union, said in a statement on Monday that it was “shocked and sickened” by the news.
“We stand in solidarity with Amir and call for the immediate removal of his punishment,” it said.
There have been widespread protests in Iran since the September death of 22-year-old Amini, who died in custody after being detained by morality police on suspicion of breaking the country’s strict rules around head coverings.
On December 8, Iran conducted its first execution in relation to the protests.
The Guardian reported that Mohsen Shekari was executed after being accused of blocking a street and wounding a member of the pro-regime Basij militia in September.
State media published a video of what it said was Shekari’s confession, which showed him with a bruising on his face.
Human rights groups, including the Oslo-based group Iran Human Rights, have said Shekari was tortured and forced to confess.
Nuclear fusion breakthrough ‘an enormous game changer,’ Constellation Energy CEO says
Grace O’Donnell, Assistant Editor – December 13, 2022
The U.S. Department of Energy announced a breakthrough in nuclear fusion on Tuesday that puts the world one step closer to harnessing an abundant energy source free from carbon emissions and long-lived radioactive waste.
U.S. Energy Secretary Jennifer Granholm confirmed that scientists achieved a reaction that created more energy than was used — known as a net energy gain — at the federally-funded Lawrence Livermore National Laboratory in California.
“Last week at the Lawrence Livermore National Laboratory in California, scientists at the National Ignition Facility achieved fusion ignition,” Sec. Granholm said. “It’s the first time it’s ever been done. … Simply put, this is one of the most impressive scientific feats of the 21st century.”
Such a development carries broad implications for renewable energy and long-term solutions to replace fossil fuels, though the benefits are still decades away.
“It’d be an enormous game changer,” Constellation Energy CEO Joe Dominguez told Yahoo Finance Live on Monday (video above). “We’ve been chasing this for a long time. But the developments we saw out of Lawrence Livermore are, I think, the best developments on fusion energy that we’ve seen since the work at Princeton probably 30 years ago with the TFTR [Tokamak Fusion Test Reactor]. So it’s very exciting. It’s transformational.”

A nuclear fusion reaction, which is what keeps the sun and other stars burning, occurs when the nuclei of two atoms fuse into one atomic nucleus. When that happens, the excess mass converts into energy. (The reverse process, nuclear fission, powers existing nuclear power plants and bombs.)
Scientists have been working to achieve sustained nuclear fusion since the Lawrence Livermore Laboratory was founded in the 1950s, but replicating the conditions found within the massive cores of stars in labs on earth has proven to be a seemingly intractable problem.
One difficulty has been in running the reaction long enough to ignite a chain of reactions. Another related challenge has been unleashing larger amounts of energy.
Experts say that nuclear fusion releases 4 million times more energy than burning oil or coal. Put another way, a pickup truck filled with nuclear fusion fuel has the equivalent energy of 2 million metric tons of coal or 10 million barrels of oil. And it produces that energy without the drawbacks of other sources, namely climate change causing carbon emissions and lasting hazardous waste.

Recent years have shown more promising results, partly due to improved technology and a growing appetite for zero-carbon energy. Donut-shaped reactors using large magnets have been able to extend the time of the reaction. Earlier this year, one such reactor in China set a record for the longest sustained nuclear fusion reaction at 17 minutes. Other tests have claimed to reach a breakeven point, meaning the energy output equaled the energy put into the test.
The development at the Lawrence Livermore Laboratory has seemingly gone further. The National Ignition Facility (NIF) uses a different method of causing fusion by directing powerful lasers at a capsule of hydrogen atoms to generate the pressure and heat necessary.
According to The Financial Times, which first reported the news Sunday, preliminary results show ignition took place, producing 2.5 megajoules of energy, or 120% of the energy that was consumed by the lasers.
That marks a long-awaited advancement in what has been considered a moonshot technology for decades. However, there’s still a long runway ahead to move from small reactions in laboratory settings to commercial nuclear reactors.
Specifically, nuclear fusion won’t help the world reach its 2030 net-zero targets. It may start to come into play by 2050.
“I still think we’re decades away,” Dominguez said. “But this development, where we’re now getting more energy out of the reaction than we’re putting in to create the reaction, is a gigantic milestone.”
At Lake Powell, a ‘front-row seat’ to a drying Colorado River and an uncertain future
Brandon Loomis, Arizona Republic – December 13, 2022
PAGE — At his office whiteboard on this dam town’s desert edge, the water utility manager recited the federal government’s latest measures of the colossal reservoir that lay 4 miles down the road, then scrawled an ominous sketch showing how far it has shrunk.
In his stylized drawing of Lake Powell, the surfacelapped just above where he marked his town’s drinking water pipe, bringing the Colorado River drought crisis uncomfortably close to home.
Against a diagram of Glen Canyon Dam’s concrete arch, Bryan Hill used blue marker to ink progressively shallower water lines from 22 years of Southwestern drought and overuse: 3,700 feet above sea level when full. Just 3,529 feet now.
He was updating a presentation he had created to reassure a worried City Council that it was merely time to act, not to panic. That day’s line fell just 39 feet above a black one Hill had drawn to indicate the dam’s hydropower intakes, the point at which the last of 1,320-megawatts flickers off.
As personal as the threat feels to Hill and his neighbors, his charts depicted a troubling reality for millions of other water users. If the lake keeps dropping below those generator intakes, dam managers will have difficulty pushing enough water downstream to keep Lake Mead from tanking and to satisfy the Southwest’s legal rights to water.
Lake Mead’s own decline threatens to upend a vast irrigated agricultural empire in Southern California and southwestern Arizona, and to restrict or eventually cut off a significant source of hydroelectricity and household water for the urban Southwest.
Powell once seemed Mead’s failsafe backup, a reservoir that, in a wet string of years, could accumulate far more than what the river delivers in a single year. During dry spells, it could pour its excess through Grand Canyon and into Mead, supplying users downstream.
Now the excess was gone. Hill’s drawing showed a reservoir on the brink after two decades of aridification, holding less water than it is supposed to send downstream in the coming year. Further declines could lend momentum to a long-simmering clamor for moving most or all of Powell’s stored water down to Mead.
If the snows that melt to replenish the reservoir are lower than expected this winter, the dam’s managers warn, it’s possible that water will dip below Glen Canyon Dam’s hydropower intakes by the end of 2023.
Page and a neighboring Navajo Nation community, Lechee, get their water from those same intakes, constructed at an elevation that government dam builders in the 1950s and ‘60s expected to remain forever inundated.
Bryan Hill, general manager of Page Power u0026 Water, draws the Glen Canyon Dam and Page’s water supply issues on a whiteboard on May 25, 2022, in his office. Page and neighboring Lechee get water from Lake Powell.
It was late May when Hill stood at his whiteboard, and snowmelt from the Rocky Mountains had started coursing down the Colorado to provide the storage pool a temporary, seasonal lift from its most recent record low. Still, the intakes sat just 39 feet below a surface that already had fallen 148 feet since the same date in 2000. After trees, plants and parched soil took their share, this spring’s runoff was shaping up poorly again. One more dry winter, Hill predicted, and “shit gets real.”
Page won’t go dry, for now. Its 7,500 residents and another 3,000 in Lechee will draw water from an emergency pipe link that federal officials are designing and connecting to tap deeper tunnels that allow managers to bypass the hydro powerplant when necessary or desired, such as for environmental flows downstream in Grand Canyon.
Even those tunnels are at risk of drying in coming years. Soon, the region’s accelerating aridification will force Page, like the vast irrigated farms and growing metropolises throughout the Southwest, to dig deeper for a solution.
A houseboat is anchored on Clear Creek at Lake Powell on Aug. 16, 2022. The future of Lake Powell, including its recreation opportunities, is uncertain after years of decreasing water levels.
Already, southern Nevada has spent $817 million to build a deeper tunnel under Lake Mead — a new “straw” into the reservoir — to keep water flowing to Las Vegas.
There are 40 million people who rely on the Colorado River water stored here, and millions more who eat the vegetables, beef and winter greens that it grows. They all face hazards on the desiccated horizon. For the few thousand who live on a red-rock bluff by the plunging reservoir, it’s in full view.
“It’s an American problem,” Hill said. “We just have a front-row seat.”
Those who love free-flowing rivers see this problem as an opportunity. Their canyon is returning, and with it the rapids and awe-inspiring rock features. Others fear the price spikes that will come with replacing the dam’s hydropower with other sources, or the loss of a motorized playground that provided thousands of jobs for decades.
As the Southwest braces for a worsening water crisis, one of its major holding tanks faces a growing identity crisis. Nature will have the final word in determining what Powell becomes, further draining it if drought worsens or refilling it if a wet period ensues. If recent trends hold, federal water managers face tough decisions in the next few years about how hard to fight to retain a shrunken lake at Page, and at what cost to other resources and users up and down the river.

Drought weakens Lake Powell’s promise
Controversial from the start, 59-year-old Glen Canyon Dam arose as a compromise of sorts. Its construction sacrificed a secluded maze of desert river and side canyons after the U.S. rejected plans to flood other treasures, sparing places like Utah’s Dinosaur National Monument. After the dam buried Glen Canyon, environmental concerns ended a scheme for more dams in Arizona’s Grand Canyon, whose “grandeur,” “sublimity” and “great loneliness” President Theodore Roosevelt had famously cautioned could not be improved upon.
The government built Glen Canyon Dam in large part to ensure that exactly what is happening in 2022 would not happen. With Hoover Dam already impounding the nation’s largest reservoir in Lake Mead near Las Vegas, the river was ready to supply water to farms and cities in Arizona, Nevada, California and Mexico.
A second reservoir upstream at Lake Powell would almost double that capacity, theoretically ensuring that the headwaters states — Wyoming, Colorado, Utah and New Mexico— could store enough water there near the Utah-Arizona line to top Lake Mead off when needed.
Instead, Lake Mead’s decline has already triggered mandatory shortages for the Central Arizona Project and the Southern Nevada Water Authority, with deeper cuts in store for next year. Arizona will give up about a fifth of its normal share of the river in 2023, deepening the hardship for farmers in the middle of the state and reducing cities’ ability to store water in their aquifers for later use.
California’s senior water rights have so far protected it from reductions. Arizona decades ago accepted junior rights as a condition of congressional approval for the CAP canal that delivers water to Phoenix and Tucson.
When the states and federal dam operators split up shares of the river on paper in the 20th century, they gave 7.5 million acre-feet of water to the three states below Lees Ferry, a spot downstream of present-day Glen Canyon Dam, and an equal share to four states that share the upper Colorado and its largest tributary, the Green River. That would add up to 15 million acre-feet, with a few million more dedicated to evaporation and Mexico. Yet in this century, the river’s natural flow has averaged far less than was spoken for, just 12.4 million acre-feet.
An acre-foot — the amount it takes to cover an acre to a 12-inch depth — is the government’s water accounting unit and contains about 326,000 gallons. Each acre-foot can support two or three households, though a large majority of the Colorado’s water goes to farms.
Now, mighty Lake Powell, big enough to fit 25 million acre-feet on its own, is just a quarter full. Dam managers made emergency releases from smaller upstream dams earlier this year to prop up the reservoir, and also held back 480,000 acre-feet that otherwise would have flowed to Lake Mead.
On paper, the government decided to treat those 480,000 acre-feet as if they were already in Lake Mead, to keep that reservoir’s official holdings from triggering even greater austerity on downstream users. Winter weather will determine whether Powell can afford to let that water flow downstream next year and still produce power.
For next year, an official with Reclamation’s Upper Colorado Basin office said, the agency will work with states on a plan to release more from upstream reservoirs and to determine what administrative steps are necessary to continue releasing only 7 million acre-feet a year from Powell, if necessary, an amount made possible by the cutbacks in Arizona, Nevada and Mexico.
In announcing next year’s shortage, Reclamation officials said the conservation efforts throughout the Colorado River basin must increase by 600,000 to 4.2 million acre-feet a year, depending on weather, to stabilize the reservoirs at current levels over the next four years. That worst-case figure, 4.2 million, represents more than a third of what the river’s flow has averaged during the long drought. It’s almost as much as California, the biggest user, takes from the river.
It’s unclear where such a large savings could be found, though the region’s Democratic senators won $4 billion in climate legislation passed this summer. It could help pay for efficiency upgrades and to compensate farmers who agree not to use their full share of the river.
Eric Balken of the Glen Canyon Institute hikes up Lake Canyon on Aug. 16, 2022. This area in Lake Canyon was under water for approximately 20 years and now has been dry for approximately 20 years, due to declining lake levels. The area has seen a resurgence of vegetation, like Goodding’s Willow.
‘I’m not the one draining this’
As the receding waters expose canyons, rock features and even whitewater rapids that long were buried under the reservoir, some who love the river for itself see nature reclaiming its rightful place.
“You can hear it,” Utahn Eric Balken said as he tromped through dense cattails and creekside willows during his first inspection of the reemerging Slick Rock Canyon, one of many remote watershedsnotched into Glen Canyon’s sandstone. “There’s lots of bugs buzzing around. I was stepping over frogs left and right.”
Discoveries like these thrill Balken, who directs the nonprofit Glen Canyon Institute. His organization has long advocated draining Lake Powell and storing its water downstream in the similarly depleted Lake Mead. Now, he figured, nature was doing his work for him. He and allies believe Lake Mead was always enough to serve the region’s needs, and that it makes little sense to divide the water now that it’s so low.
Indian paintbrush grows in Lake Canyon on Lake Powell. As water recedes, plants and animals are returning to canyons that were once under water.
Motoring out of Bullfrog Marina in mid-August, he said he tries to keep a low profile when boating from canyon to canyon, given how attached house boaters and water skiers are to their impounded playground. Soon, though, it may not matter what anyone wants for Lake Powell.
“Guess what?” Balken said. “I’m not the one draining this.”
Slick Rock, south of Halls Crossing, now supported multiple beaver dams and ponds, but also held disappointments for Balken. Tumbleweeds choked the zone nearest the retreating reservoir, while a nonnative grass vine crisscrossed the creek bed and threatened to outcompete the native flowers and grasses seeking a foothold. There are remnants of a dam-altered floodplain that he hopes will fade as nature takes over.
A notch to the north, Lake Canyon, yielded unequivocal joy for Balken the next morning. He throttled his boat up the meandering sandstone canyon and past a slalom of ghostly gray cottonwoods that still jut from the flatwater that buried them in the 20th century. He drove a sand spike into the beach to secure the boat, marched through a wall of briars and over a logjam deposited by recent flash flood, then emerged into an open canyon with a flowing stream.
Soon, a rushing waterfall echoed from the canyon walls and pitched muddy water from its bedrock perch like a monsoon deluge draining from a flat-roofed adobe.
Walking up on resurrected features like this, or on rock grottos or natural bridges elsewhere around Lake Powell, feels a bit like discovering Atlantis, long rumored to exist under the sea but buried under the waves for ages. The upper reaches of Lake Canyon’s dam-flooded zone first saw daylight again some 20 years ago, but this particular waterfall remained inundated until more recently.
Gregory Natural Bridge at Lake Powell pictured on Aug. 15, 2022. Until recently, this natural bridge was entirely under water.
Even after the water retreated, Balken and colleagues three years ago walked across lakebed sediments that still entombed it. Flash floods apparently blew out those deposits to expose the falls, which in turn blew his mind when he first saw it and heard its power.
“I love to see a creek finding its original bed,” he said.
More consequential treats awaited as he ascended the canyon this time. Atop the falls, 15-foot willows sprang out of a cutbank and rang with birdsong, evidence that the native vegetation and rust-colored canyon wrens can quickly return here.
Around elevation 3,650 feet, a mark that first reemerged some 20 years ago, some willows reached to 40 feet. Then came the cottonwoods, towering kings of the desert oasis, first one seedling at a time, then in tall clusters at higher elevations, and finally in dense ribbons of forest. Underfoot, purple wildflowers sprouted. Cicadas droned.
In the 1950s and ‘60s, when Reclamation Commissioner Floyd Dominy pushed for and finished the dam, Balken said, the dam builder had argued there was nothing of value to preserve there. Indeed, into his old age early in this century, Dominy asserted that he had improved the environment.
“I believe that nature can be improved upon,” he told High Country News in 2000, when Powell was nearly full and only academics used the term “megadrought.”
“This is a miracle,” Balken said in Lake Canyon’s recovery zone. “Our values have clearly evolved. Clearly, there is something here.”
But one canyon’s gain may be another’s loss.

Jack Schmidt traveled to a park in Moab, Utah, on a June evening to explain the Colorado’s woes to a few dozen interested Utahns and Canyon Country visitors. Schmidt is a Utah State University watershed scientist who has spent his career studying the river, and he leads a band of regional researchers who publish science and policy white papers through the Center for Colorado River Studies. To his eyes, Glen Canyon’s reemergence is both locally beautiful and regionally troubling.
“Don’t kid yourself into thinking the only environmental issue is everything wonderful in Glen Canyon popping up again,” Schmidt said to the crowd assembled on folding lawn chairs for a weekly Science Moab discussion and movie viewing. (The post-apocalyptic sci-fi “Waterworld” was the flick that week.)
During the Obama administration he served as head of the Grand Canyon Research and Monitoring Center for 3 ½ years, and before that he proposed what would become a series of artificial floods from Glen Canyon Dam to push sand downstream and offset some of the dam’s profound damage to the Grand Canyon’s ecology.
But Schmidt had another threat to Grand Canyon on his mind. Smallmouth bass were massing just upstream of Glen Canyon Dam, where the declining water levels brought the lake’s relatively warm surface close to the hydropower intakes. If enough bass or other nonnative, warm-water sportfish slipped through the turbines to start a downstream population, they could menace a recovering population of native humpback chubs.
Paul McNabb holds a small mouth bass, while Utah State University researchers record fish species during a survey on June 9, 2022, above Glen Canyon Dam on Lake Powell.
If that happens, he said, it’s “game over” for a fish that has swum Grand Canyon for millennia.
On that summer evening in the park, Schmidt urged his listeners to demand action if they care about saving the river environment. The United States must address two seemingly intractable problems, he noted: climate change and overuse.

The challenges of climate and overuse
Scientists have explained the long-term crisis that a warming Rocky Mountain region is imposing on the Southwest as a “hot drought.” As the region warms, even snowpacks that seem healthy while piled up in the mountains can result in a trickle into reservoirs after the atmosphere, stressed trees and dry soils soak up their share.
A 2017 study by scientists at the University of Arizona and Colorado State University found that warming exacerbated the current drought to reduce annual flows by about a fifth, and that unabated greenhouse gas emissions through this century could push losses to a third or more of the river’s normal flow.
Lake Powell near Bullfrog Marina pictured on Aug. 15, 2022. Previous water levels are visible on the walls surrounding the lake.
The Bureau of Reclamation itself warned a decade ago that climate change would eat into the river. Its projections of a 9% reduction in flows by mid-century underestimated what has already happened to the river.
“The important point,” Schmidt told his audience that day in Moab, more than 300 miles from his home campus, “is I shouldn’t have driven down here from Logan in a gas-guzzling van and loaded the atmosphere with carbon, I guess.”
The second problem, overuse, is more immediate. In recent years, the dam-stored equivalent of the entire, shrunken river’s flow has gone to supply California, Arizona, Nevada and Mexico, including evaporation in Lake Mead. Although the less-populous upstream states of Wyoming, Utah, Colorado and New Mexico take much less, the combined effect is depletion of reservoirs that once held several years’ worth of flows.
Schmidt’s solution, he would later tell The Arizona Republic, is to reengineer Glen Canyon Dam to allow it to spill water into the river and through Grand Canyon even after it sinks lower than the existing hydropower intakes and bypass tunnels. That might require drilling new and lower tunnels through the sandstone beside the dam. At least, he said, the government must study that option, because without it the drought could push the reservoir into “dead pool,” when a river no longer flows from it until more snowmelt arrives to buoy the surface.
“We should know what it costs to bypass,” Schmidt said.
On that, Schmidt and Glen Canyon preservationists like Balken agree. The Glen Canyon Institute this summer joined the Utah Rivers Council and Great Basin Water Network in calling on the Bureau of Reclamation to study such a plan that would, effectively, allow managers to drain Powell while leaving the dam in place.
The Colorado River (right), pictured on June 11, 2022, near Hite, Utah. The sediment delta and Lake Powell’s low water levels have cut off Farley Canyon (bottom left) and White Creek Canyon (top left) from the river and what used to be Lake Powell.
But Schmidt would not drain the lake. Instead, he said, lower bypass tunnels would allow the government to decide how much storage Lake Powell needs in order to consistently send water downstream based on Grand Canyon’s environmental needs. It would still hold back water, but in dry times Lake Mead would need to handle the bulk of the Southwest’s storage needs. Reengineering the dam could cost tens or hundreds of millions of dollars, depending on the design. The Bureau of Reclamation has directed $2 million toward a study of options.
“There’s no way in this country we’ll eliminate the potential storage at Powell,” Schmidt said. The question is how often it will be actual storage, and how often mostly potential.
A boat cruises on Lake Powell near Bullfrog Marina on Aug. 15, 2022. Boat ramps have had to be extended multiple times as water levels receded at Lake Powell.
Tough choices for recreation
The National Park Service has spent several million dollars extending concrete boat ramps at Stateline in the south of Lake Powell and Bullfrog in the north, to enable continued access for houseboats. But that work likely won’t be enough to support the park’s congressional mandate to manage for boat recreation, and so the agency is planning a bigger investment.
The Bullfrog Marina ramp can handle houseboats only until the reservoir’s surface sinks below elevation 3,529 feet, park officials said in August. By then the spring snowmelt runoff had helped the lake rebound past that point, precisely where it had hovered when Hill had drawn it on his whiteboard in March.
A Bullfrog Marina employee fuels a watercraft at Lake Powell on Aug. 16, 2022. The marina was scheduled to be moved into the Colorado River main channel because of declining water levels.
The Bureau of Reclamation’s current projections show Lake Powell likely dropping back below that mark in September but rising to it again by next June. Seeking a longer-term solution, the Park Service is applying $26 million in federal disaster funding it received this year toward building a new ramp at Stanton Creek, a nearby but deeper part of the lake that could reach elevation 3,450 feet. That would enable boating well after the reservoir drops below the point of generating electricity.
The uncertainty is forcing boaters to make hard choices. Tom Parker, a semi-retired contractor from Erda, Utah, wasn’t sure whether to haul his houseboat out from its mooring at Bullfrog as the season winds down. He wanted to get it on dry land to scrape off the quagga mussels that crust over the hull, the engine and water intakes. But with the reservoir continuing to fall, he wasn’t sure he could risk it.
“If you get it out, you might not get it back in. That’s the problem,” he said while lining up on the ramp on a mid-August morning.
Parker was launching personal watercraft for his children and grandchildren to zoom around on during a stay on the houseboat. That’s something he’s done routinely over the years, as someone from his extended family visits the boat at least every other week in summer. Some even work remotely from it now that there’s a satellite internet link.
Eric Balken of the Glen Canyon Institute dismantles a rock dam at the base of the waterfalls at Cathedral in the Desert on Aug. 15, 2022, at Lake Powell.
‘You can’t improve on nature’
Balken, the activist who longs for the reservoir’s demise and the river’s return, acknowledges that lots of people love lake recreation. Before them, though, there were those who loved the river and loathed what became of it after the dam. They include people he has known, like the late singer and renowned river guide Katie Lee, who didn’t live to see Glen Canyon’s return, and Ken Sleight, also a pre-dam guide and one who still yearns for the death of “Lake Foul.” Balken said he’s motivated partly by “the pain of their loss.”
Eric Balken of the Glen Canyon Institute rests at Cathedral in the Desert on Aug. 15, 2022, at Lake Powell. This area, known for its beauty, was buried when Lake Powell filled.
One of their losses was Cathedral in the Desert, a shady sandstone grotto in a side canyon that admits a beam of sunshine to backlight a ribbon of water falling through a narrow slot. It was a place Sleight discovered while guiding tourists out of Escalante, Utah, on horseback before Lake Powell flooded it. Today, it’s back from the depths.
When Balken approached its sandy base in bare feet this summer, he found a row of rocks that someone had placed as a dam across the stream at its base, perhaps to raise a pool for bathing beneath the falls. He promptly chucked the rocks aside.
“You can’t improve on nature,” he said.
At home outside of Moab, Sleight looked at freshly shot digital photos of his beloved Cathedral in the Desert, and at new images of other side canyons. Their rebirth pleased him, but had taken too long.
“I don’t think I’ll be doing any more river running,” he said. “I wish I could.”
Ken Sleight pictured on Aug. 17, 2022, in Moab, Utah. The guide inspired a character in author and friend Edward Abbey’s book u0022The Monkey Wrench Gang.u0022
Sleight spoke softly and haltingly while sunken into his sofa, worn down from days of waging his own struggle with the fickle climate. A wildfire last year denuded the hills above his home, and recent monsoon rains had rushed over the bare ground and washed out small bridges on his property. He and wife, Jane, had been busy with repairs.
In younger days, the guide had befriended author Edward Abbey partly out of a shared disdain for the dam, and he had inspired a character, Seldom Seen Smith, in Abbey’s signature novel, “The Monkey Wrench Gang.” He still invokes his late friend’s prayer “for a precision earthquake to take down the dam,” but says he doubts it will now take an act of God to drain the reservoir.
“I’m 93 now and I don’t have too much time to live,” he said, “but I’m sure hoping I can live long enough to see it go.”
If the Colorado does flow freely through Glen Canyon again, he fears, there will be a new threat: people. Even before the dam, he remembered, the place had become crowded for his taste. A renewed Glen Canyon will require careful management, he believes. “It’s going to attract thousands, because it’s so beautiful.”
North Wash boat ramp, June 10, 2022, on the Colorado River, near Hite, Utah.
Amid new beauty, dangers lurk
From an airplane over Lake Powell’s upper reaches, the folds and crevasses of mud resemble a dirty glacier plowing through the Colorado Plateau.
As the reservoir retreats from the floodplain’s edge, where for decades the river dropped sediment it had eroded from points upstream, the accumulation slumps raggedly away from sandstone walls as a fault line would in an earthquake.
This is no flightseeing tour of geologic time, exhibiting Earth’s grindingly slow mechanics as they carve Canyon Country’s latest wonder. It is instead a real-time window on the fast-moving consequences of a changing, drying regional climate and the Southwest’s slow response to it as Lake Powell drains toward oblivion.
A Western River Expeditions raft is taken off the Colorado River at North Wash boat ramp near Hite, Utah, on June 10, 2022.
River rafters paddling or motoring down from Moab years ago were forced to abandon the Hite takeout ramp on the narrow upper lake’s east side, in favor of an intimidating gravel incline called North Wash on the west side. The makeshift ramp has steepened as the bank at its bottom continues to slough, making for a difficult retrieval of the big, motor-equipped rafts that tour company guides pilot down from Moab daily in summer.
After customers step out and walk toward a waiting bus, a pickup with a trailer backs gingerly down the top of the embankment and sets its brake. Guides from multiple boats then push and pull the rafts uphill on inflatable rollers. The combination of massive loads on the hill and deep muddy waters at the bottom requires vigilance.
“It’s scary,” Hannah Wood, a seasonal Moab-based guide from northern Utah’s Salt Lake valley, said when she arrived at North Wash after a June trip. “Every time we come here I’m worried someone will die.”
Wood said a colleague had fallen at the ever-changing takeout’s edge, and had cut himself on the raft’s motor. While the rapids upstream in Cataract Canyon are supposed to be the trip’s big thrill, she said, takeout at this site is “the most dangerous part of our job.”
A boat cruises on Lake Powell near Bullfrog Marina on Aug. 15, 2022. Lake Powell was at 25% of capacity and more than 160 feet below full pool.
The only other place to take out is at Bullfrog Marina, a two-day motor across flatwater. But even that has become problematic for operators of larger rafts, as the shifting and shallow mud beneath the delta that’s emerging downstream of North Wash can trap the heavy rigs.
The river also appears to be building a waterfall over a sediment deposit upstream of the North Wash takeout, threatening further complications.
The same thing happened hundreds of miles downstream when Lake Mead drained away from the lower Grand Canyon. There, a waterfall made Pearce Ferry the final takeout chance for Grand Canyon river trips.
Already, North Wash is “probably the worst boat ramp in North America,” Moab river runner and pilot Chris Benson said while looking down from a rented four-seat Cessna Skyhawk that’s usually used to give rafting patrons a look at Canyonlands National Park on the way back to their cars in Moab.
The North Wash boat ramp (center, right of river) on the Colorado River, near Hite, Utah, pictured on June 10, 2022. The way Lake Powell has receded has limited takeout points for river rafters.
Benson’s friend, river guide Pete Lefebvre, pointed to a muddy riffle upstream of the ramp, near where the Dirty Devil River meets the Colorado, fresh evidence of a fast-changing landscape. “That wasn’t there two days ago,” he said.
Benson and Lefebvre are amateur “investigators” with a small nonprofit group of river enthusiasts called Returning Rapids. They photograph and share changes in the river and lake environment as the water recedes. Their work can help other recreationists navigate new hazards, but increasingly they also want government officials to take notice. As the reservoir’s northern edge creeps downstream, they say, the river is pushing its mud delta farther south.
Mike DeHoff (right), with the Returning Rapids Project, points out the sediment delta on a map of the Colorado River at Swanny City Park in Moab, Utah, on June 10, 2022,
This mud is what the group considers the “tailings” from the region’s “mining” of the Colorado River: The West used up the water and left a mess more than a hundred feet deep. They call these deposits the “Dominy Formation,” in honor of the late dam builder.
Farther downlake, the San Juan River, a major tributary that joins the reservoir, has pushed its delta closer to Lake Powell’s main channel. When that happens, possibly in a few years, they fear the band of mud could at least temporarily cut Lake Powell in two, creating a new set of hazards.
Who will mind the mud? How will it affect recreation, the environment and safety? To date, there’s no plan.
“Are we making a conscious decision?” Lefebvre said. “Or are we just saying, ‘Oh, that’s Lake Powell. That’s just what happens.’”
A Western River Expeditions raft is taken out of the Colorado River at North Wash boat ramp, near Hite, Utah, on June 10, 2022.
Worried as they are about the mud, Returning Rapids members are unabashedly joyful about what else the reservoir’s decline is giving them. It’s in their name: the whitewater rapids that are rising again from lower Cataract Canyon, the river stretch that is no longer inundated.
Eleven rapids have returned, clearly visible from the air and adding about 50% more fun to the 22 that the float trip previously offered. Lefebvre points them out from above, each the result of a side canyon whose drainage has poured boulders into the Colorado over the ages. Several of them have emerged alongside sandy camping beaches of the sort that river runners covet.
“Good for us!” Lefebvre said.
At North Wash, where Wood was helping offload rafting clients and trailer the rafts in June, one client said he had a blast on his multiday river trip, but worried about what Lake Powell’s plunging waterline portends.
“In 20 years the Colorado River won’t be here,” said Jeff Dudek, a tourist from Prairieville, Louisiana, “unless something drastic happens.”
Will hydropower survive the crisis?

More than 4 million Americans who buy Glen Canyon Dam’s power also stand to lose as the water recedes. Consumer-owned utilities from Arizona to Wyoming, including Native American entities like the Navajo Tribal Utility Authority, will need to add new and likely costlier sources to their mix.
Supplemental sources could include solar, pumped-storage hydro projects or even small, modular nuclear plants, said Leslie James, who directs the Colorado River Energy Distributors Association. If Glen Canyon loses all of its power-generating capacity, it would shut off the primary revenue source that pays for the dam’s operations and maintenance. The dam accounts for $119 million of the $150 million that electric generation pumps into a basin fund that also aids environmental initiatives on the river.
Looking at the government’s current projections for flows and reservoir levels, she fears Glen Canyon water will dip below the minimum level for power production by 2024.
Before then, James hopes, a bill proposed by Sen. Mark Kelly, D-Ariz., could help limit the pain. Kelly’s bill would keep the government from collecting standard operations and maintenance or dam financing fees from hydropower customers when the dam isn’t actually churning out electricity because of drought.
Improved forecasting technology could help the Bureau of Reclamation fine-tune releases from upstream reservoirs such as Navajo or Flaming Gorge to maximize their effect. Ultimately, though, the river’s hydropower users are at nature’s mercy.
“It needs to rain and snow,” James said.

Learning to live with less
At the Navajo community of Lechee, outside of Page, coping with drought is a way of life. The houses, many of them mobile homes, have brown yards. Rural residents beyond the village have cut back on sheep and cow herds, partly to offset the cost of hauling water and partly because there’s little grass for the livestock to eat.
And yet, like Page, Lechee exists as a population center because of Lake Powell and access to its water.
Jimmy Shaw of White Mesa fills the 55-gallon barrels in the back of his truck at the Marathon water station in Page on May 26, 2022. Shaw hauls water for his sheep, goats and cattle.
“My parents remember when it was just a little bitty stream, before the dam came,” said JoAnne Yazzie-Pioche, who heads local government as the Lechee chapter president. Navajos made do with groundwater pumped by windmills, and did not build their homes next to each other.
Then Page tapped the dam, and Lechee got access to water piped from the same intake. With that, some congregated around the village water tower, while others remained in rural homes but trucked water from a filing station in town. They brought water to maintain livestock, but are now culling herds because of both the expense of hauling and the drought-stricken forage.
Watching Lake Powell’s decline has been painful for Yazzie-Pioche, for multiple reasons.
For one, her dad was a laborer who helped build Glen Canyon Dam during her childhood. She frequently boated and camped on the lake for recreation while raising her own children, back when the monolith Lone Rock on the lake’s south end was surrounded by water.
“We love Lake Powell,” she said, though her children have grown and moved to metro Phoenix, and the lower water has reduced the draw for her personally. “It’s sad to see. And not a whole lot of beaches. But still, people do come.”
Her community, like neighboring Page, is hoping for a new water source that draws from deeper than the dam’s hydropower intakes. The Navajo Nation has begun work on a pipeline from the pump upstream of the dam that supplied cooling water to the now demolished coal-fired Navajo Generating Station.
Even before it comes online, the plunging water line is raising questions about this new source’s viability.
“We’re just like, ‘Great. We finally have access to Lake Powell on this side, on the (Navajo) Nation’s side, but the water’s going down,” Yazzie-Pioche said.
The Southwest must learn to live with less, she said, from the lawns of Phoenix to the farms of Yuma. Whatever happens along the Colorado, though, there will still be windmills around Lechee.
“We’re always going to be here,” she said. “We were here prior. Even when we had no water, people still lived here.”
Marjorie Bigman shears a sheep on May 24, 2022, near Coppermine on the Navajo Nation.
Page was not there before the big water. It was founded in the 1950s to house the workers who built Glen Canyon Dam. They came to improve on nature.
“The federal government built Page,” said Hill, the city’s utility director. ‘Yea verily,’ in 1957 they said, ‘There shall be Page.’”
It was a proclamation with echoes across the Colorado River’s 1,450-mile length, not least along the federally backed projects importing water to Phoenix and Los Angeles.
What the government created, Hill said, the government should fix. Page needs a new and deeper intake beyond the quick fix that the Bureau of Reclamation is planning within the dam. A new intake outside of the dam would protect the city’s supply of drinking water even if drought pushes the lake to “dead pool,” lower than the dam’s bypass tunnels. But it will cost $40 million, he said. The city is angling for federal funds to build it.
Whatever identity Lake Powell ultimately assumes, the costs will ripple far beyond its waters.

Chinese Rocket Stage Now a Cloud of Orbital Debris After Disintegrating in Space
Passant Rabie – December 13, 2022
China’s Long March-5B Y3 rocket carried the Wentian lab module to China’s space station in July.
On November 12, China’s Long March 6A rocket broke apart after launch, scattering debris in low Earth orbit. Now, reports suggest that the disintegrated upper stage of the rocket has grown to a cloud of 350 pieces of space debris.
The rocket launched at 5:52 p.m. ET on November 11 from Taiyuan Satellite Launch Center in north China, carrying the Yunhai 3 environmental monitoring satellite.
Shortly after delivering the satellite to low Earth orbit, the upper stage of the Long March 6A rocket broke apart, the South China Morning Post reported at the time. The U.S. Space Force’s 18th Space Defense Squadron tracked 50 pieces of space debris resulting from the rocket’s break up at an estimated altitude of 310 miles to 435 miles (500 to 700 kilometers), the squadron announced on November 13.
Nearly a month later, experts are still tracking the disintegrated pieces from the rocket. “There are now 350 debris objects cataloged from the Nov 12 disintegration of a Chinese rocket stage (CZ-6A Y2), in sun-sync orbit,” Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, wrote on Twitter based on ongoing tracking by the Space Defense Squadron.
China has been reckless with its rockets before, but the Long March 6A rocket breakup wasn’t meant to happen. The rocket’s upper stage was supposed to reenter Earth’s atmosphere in one piece, and burn up during reentry. It’s not clear what went wrong to cause the rocket to break up before its reentry.
The rocket breakup sent debris flying near Starlink’s internet satellites, but Chinese officials are claiming that pieces of the rocket will not threaten other low Earth orbit assets. “As far as we know, the relevant incident will not affect the Chinese space station or the International Space Station,” Mao Ning, spokesperson for China’s Foreign Ministry, is quoted in the South China Morning Post as saying during a press conference.
As of last year, more than 27,000 pieces of space debris were being tracked in orbit by the Department of Defense’s global Space Surveillance Network, with lots of smaller pieces also floating around undetected.
Tempted to joke about global warming amid a blizzard? Here’s what experts say about that.
Elizabeth Weise, USA TODAY – December 13, 2022
Winter storms are pummeling the United States, snow is piling up, temperatures are dropping, traffic is snarling and there’s always the threat of thunderstorms and thundersnow.
Just like clockwork, the emails, tweets and Facebook posts start flowing. Maybe it’s a joke, maybe it’s a snarky critique, maybe it’s a meme. The words change, but the format is familiar: If global warming is real, why is it so cold out?
Scientists likely don’t think that joke is as funny as another familiar climate change quip: Never argue about climate change – it always turns into a heated debate.
But we asked experts to weigh in on the winter weather trope. Here’s a few thoughts on what winter means in an era of global warming.
Cold winters don’t mean there’s no global warming
Atmospheric science professor Dan Chavas at Purdue University in Indiana says these arguments don’t frustrate him because they’re a chance to engage.
“I think most of the time when people say that, they are joking and do not seriously believe that the occurrence of winter disproves climate change,” he said. “For me personally as a scientist, I see that type of comment as a potential opportunity to talk about climate, the seasons, and climate change if they seem interested.”
He starts that conversation by agreeing that climate has always had seasons, but notes climate change is a gradual warming – on top of the seasons – that’s making winters, springs, summers and falls all warmer over time.
Higher temperatures don’t mean it’s hotter everywhere all the time
Global temperatures have risen 1.9 degrees Fahrenheit since 1880. That doesn’t mean it’s hotter everywhere all at once but that the entire system is becoming more volatile.
“As you add energy to the system, both extremes grow. You can have Texas ice storms as well as 33 million people displaced in Pakistan due to heat and flooding,” said Julio Friedmann, chief scientist at Carbon Direct, a carbon-management firm and a former professor at Columbia University. “These sorts of changes were predicted in 1996, it’s not news that this is happening.”
That said, winters are indeed getting warmer.
Since 1896, average winter temperatures across the lower 48 states have increased by nearly 3 degrees, according to the Environmental Protection Agency. Nationally, 57% of US Weather Service stations have shown a decline in snowfall since the 1930s.
Winter weather is now on average 14-and-a-half days shorter and summers are seven and a half days longer, according to Brian Brettschneider, a climate scientist with the University of Alaska at Fairbanks
“Global warming will not stop the seasons, but it is causing long-term trends in winter conditions that are robust and accelerating,” said Jason Smerdon, a climate physicist at Columbia University.
The odds are shifting to hotter extremes
But climate change is never all one thing or another. Rather it is a shift in the odds of occurrences of extremes, said Gerald Meehl, a senior scientist with the National Center for Atmospheric Research.
Over the U.S. during the past decade, it is twice as likely that a daily record high maximum temperature occurred at a given location compared to a daily record low minimum, he said.
“For every two daily record high maximums that are set, there is only one daily record low minimum. This is climate change happening before our eyes,” he said. “If the climate wasn’t warming, there would be an equal chance of a daily record high temperature being set compared to a daily record low minimum.”
Over the rest of this century, the number of extreme heat events will rise, even though there are a few extreme cold events.
“I’ve said that the scientist sitting at my desk in the year 2100 will get a phone call on a cold day in January 2100 when a daily record low minimum temperature is set in Denver,” he said.
That caller will want to know what happened to global warming because a record cold temperature has just been recorded.
“That scientist in my seat will answer that yes, it was cold on that one day,” he said. “But think back to the previous summer when nearly every day set a daily record high maximum temperature.
Bombing of Putin’s Most Feared Fighters Infuriates Russia
Allison Quinn – December 13, 2022

The Russian mercenaries hailed by their leader as the most skilled and experienced soldiers in the war against Ukraine have gotten themselves blown up over the weekend.
Pro-Kremlin Russian media channels were the first to reveal the strike Sunday on a hotel in the occupied Luhansk region, furiously noting that “the enemy used HIMARS to hit the hotel in Kadiivka where Wagner fighters were located.”
Photos showed the building, a hotel called “Zhdanov’s Guest House,” blown to smithereens, though no details were immediately given on how many Wagner fighters were killed. Russian state-run media was largely mum on the whole affair (with the exception of a Kremlin-friendly tabloid saying the site had been targeted because the U.S. knew Wagner founder Yevgeny Prigozhin frequented the private army’s headquarters there.)
Ukrainian authorities say the Russian military is “carefully concealing” its losses in the strike. Serhiy Haidai, the Ukrainian governor of Luhansk, confirmed the strike and quipped on Telegram that “many” Wagner mercenaries would undoubtedly be absent for their next roll call.
On Tuesday, Haidai issued a statement saying “hundreds” of Wagnerites have been killed before reaching the frontline in the last week and a half, either by “‘explosions’ caused by smoking in their headquarters or their barracks.”
Meanwhile, Bildreported Tuesday that a selfie taken in front of the hotel in Kadiivka may have alerted Ukraine’s military to the Wagner fighters’ whereabouts and sealed their fate. Russian media channels circulated the photo, speculating that the Russian soldier shown grinning in front of “Zhdanov’s Guest House” was none other than Pavel Prigozhin, the son of the Wagner founder, who previously said his son was serving in the ranks of the private army.
It was not immediately clear when the selfie was taken, and Prigozhin himself denied that his son had been impacted by the HIMARS strike. The Daily Beast has not independently verified the authenticity of the photo and its potential links to the bombing.
“Don’t worry, my son is fine,” the Putin-friendly businessman said in a statement Sunday.
How nuclear fusion works, and why it’s a big deal for green energy that scientists made a ‘breakthrough’

Scientists produced a nuclear fusion reaction that created a net energy gain, preliminary results suggest.
The Department of Energy is expected to make an official announcement about the finding on Tuesday.
Fusion energy advocates say it’s a step forward in clean, cheap, and almost limitless electricity.
Scientists have reportedly made a “breakthrough” in their quest to harness nuclear fusion.
The US Department of Energy is expected to make an official announcement regarding the milestone in fusion energy research on Tuesday, the the Financial Times reported.
For the first time, researchers created a nuclear fusion reaction that produced more energy than they put into it, FT and the Washington Post reported.
The experiment, conducted within the last two weeks at Lawrence Livermore National Laboratory in California, generated 2.5 megajoules of energy, 120% more than the 2.1 megajoules put into creating it, FT reported, citing preliminary data.
“Scientifically, this is the first time that they showed that this is possible,” Gianluca Sarri, a physicist at Queen’s University Belfast, told New Scientist. “From theory, they knew that it should happen, but it was never seen in real life experimentally.”
What is fusion energy and why is it a big deal?

Nuclear fusion works by forcing together two atoms — most often hydrogen — to make a heavier one — like helium.
This explosive process releases massive amounts of energy, the Department of Energy explains. Fusion is the opposite of fission, the reaction that powers nuclear reactors used commercially today.
Fusion occurs naturally in the heart of the sun and the stars, providing these cosmic objects with fuel.
Since the 1950s, scientists have been trying to replicate it on Earth in order to tap into what nuclear energy advocates suggest is clean, cheap, and almost limitless electricity.
According to the International Atomic Energy Agency, fusion generates four times more energy per kilogram than the fission used to power nuclear plants, and nearly 4 million times more energy than burning oil or coal.
What’s more, unlike fossil fuels, fusion doesn’t release carbon dioxide — the greenhouse gas that’s the main driver of climate change — into the atmosphere. And unlike nuclear fission, fusion doesn’t create long-lived radioactive waste, according to the Department of Energy.

But so far, nuclear fusion hasn’t solved our energy problems on a grand scale.
What Tuesday’s ‘breakthrough’ announcement means for the future
Tuesday’s announcement is likely a huge step forward in nuclear fusion energy, but applying the technology at commercial scale is likely still years away.
Chanda Prescod-Weinstein, a theoretical physicist, pointed out that the process the Department of Energy uses requires tritium, a rare and radioactive isotope of hydrogen.
“It may yet yield important information that is ultimately transformative. We don’t know yet,” Prescod-Weinstein tweeted on Monday. “Being able to do this once a day with a laser does not at all mean that this mechanism will scale!”
What is nuclear fusion, and could it power our future?
Haley Ott – December 12, 2022
What is nuclear fusion, and could it power our future?
Scientists, governments, and companies from around the world have been increasingly investing in a potential source of energy that could provide unlimited, clean power to everyone on Earth: nuclear fusion. Fusion is the process that powers the sun and the stars. It’s the opposite of nuclear fission, the process used in today’s nuclear power plants, which splits atoms apart.
U.S. Department of Energy was expected to announce in mid-December a major breakthrough in the quest to harness the power of nuclear fusion. The Financial Times reported that scientists at the government-run Lawrence Livermore National Laboratory (LLNL) in California had managed for the first time ever to create more energy in a fusion reactor than was required to drive the process — a “net energy gain.”
U.S. Rep. Ted Lieu, a California Democrat, said if confirmed it “could be a game changer for the world” in the bid to create sustainable electricity.

In fusion, two atomic nuclei are combined to create a heavier nucleus, and the process releases energy. The reaction takes place in a state of matter called plasma, which is distinct from liquids, solids or gasses.
In the sun, nuclei collide at hot enough temperatures to overcome the electric repulsion that would normally keep them apart. When they are very close together, the attractive nuclear force between them becomes stronger than the electric repulsion, and they are able to fuse. The gravity of the sun ensures that nuclei are kept close enough together to increase their chances of colliding.
If humans can harness the power of fusion on an industrial scale, it could help create a virtually limitless source of clean energy on earth, with the power to generate four million times more energy than burning coal or oil, according to the U.N.’s International Atomic Energy Agency.
Scientists believe fusion plants would be much safer than today’s nuclear fission plants — if the process can be mastered.

“It can’t run away. It’s a very difficult reaction to sustain; it needs to be driven. Whereas fission can run on a chain reaction, and it has to be controlled,” Tim Luce, the head of science at ITER, told CBS News.
Fusion also creates much less radioactive byproduct than fission, and what it does leave behind is “not water soluble — they won’t get into the food supply, the water supply,” Luce said.
Some concepts for fusion reactors being developed today will use two types of hydrogen atoms, deuterium and tritium, for fuel.
Deuterium can be easily and cheaply extracted from sea water. Tritium, which does not exist abundantly in nature, could potentially be produced by a reaction between fusion-generated neutrons and lithium. It is also a byproduct of the nuclear fission process used in power plants around the world today.
Scientists have already managed to produce fusion reactions, but not without using more energy to trigger the process than they were able to produce through it.
Assuming scientists are able to achieve “net energy” — producing more energy than they use to create the fusion reaction — other things will still need to fall in place for fusion to become a secure, viable energy source for the world.
“We must also prepare the path broadly for fusion commercialization, going well beyond R&D,” Dr. Scott C. Hsu, lead fusion coordinator in the Office of the Undersecretary for Science and Innovation at the U.S. Department of Energy, said in a Senate hearing last month.
“This includes public engagement and energy justice, diverse workforce development, a regulatory framework that engenders public trust and supports timely deployment, market identification, attracting investment and commercialization partners, export controls, nuclear nonproliferation, cybersecurity, international coordination, building critical supply chains and manufacturing capabilities, and waste disposition,” Hsu said.
Here’s the Healthiest Way to Drink Alcohol, According to a Dietitian
Erica Sweeney – December 12, 2022
“Hearst Magazines and Yahoo may earn commission or revenue on some items through the links below.”
ENJOYING A NICE glass of red wine with dinner, sipping a tumbler of bourbon after a long day, trying a new craft beer, or mixing up your own cocktail. Everyone loves a good drink from time to time. Though drinking too much (and, we’ve all been there) isn’t good for you, it is possible to incorporate your favorite alcoholic beverage into a healthy lifestyle.
So, what is healthy drinking? “Moderation is key,” says Brittany Kunza, M.D., a medical director at virtual health platform PlushCare. “Alcohol really shouldn’t be considered ‘healthy,’ but it certainly can be part of social gatherings.”
The Centers for Disease Control and Prevention (CDC) recommends no more than two drinks a day for men and one for women. But, two-thirds of adults say they drink more than that at least once a month.
Drinking too much long-term can bring many health consequences, such as high blood pressure, heart disease, liver disease, and stomach problems. It can also weaken your immune system and increase your risk for certain cancers.
Either inspired by these health risks or striving to cut back for other reasons, many people are partaking in Dry January or permanently embracing a “sober curious” lifestyle. And, non-alcoholic, booze-inspired drinks are becoming more popular.
Many aspects of drinking can affect your health—how much you drink, how often, and your beverages of choice. A healthy approach to drinking alcohol is part of a healthy approach to life. Often, that means choosing drinks that are lower in sugar and calories, such as skipping sugary mixers and using seltzer in place of tonic.
What’s the best way to balance drinking and a healthy lifestyle?
It’s best not to overdo it when it comes to alcohol and stick to two drinks or less a day. But, having a few more from time to time likely won’t harm your health—just don’t drive when you’re drinking.
Plan Shooting 2 / Imazins
Everyone is different in terms of how they handle alcohol. Some people can drink more than others before they feel drunk.
“Alcohol impairment is an individual number that is different from person to person,” says Ernest Gelb, D.O., president of the American Osteopathic Association. “The legal limit is 0.08, but there are many individuals who can’t tolerate that much alcohol. The end result of impairment is the same and will not end well.”
It’s a good idea to understand what’s considered a “standard drink,” too, says Dr. Kunza. According to the CDC, standard drink sizes include:
12 ounces of beer
8 ounces of malt liquor
5 ounces of wine
1.5 ounces of distilled spirits, like gin, vodka, or whiskey
What Kinds of Alcohol Are the Healthiest Options?
Ignore the myths you heard in high school about your body processing certain alcoholic beverages in different ways. Your liver doesn’t recognize wine from beer from a Long Island Iced Tea—it only processes alcohol.
That said, if a drink is higher in alcohol, your liver has to work hard. So if you’re drinking a finger of Scotch whisky neat (typically about 40% alcohol by volume, or ABV), your liver is going to have an easier time than with that Long Island Iced Tea (typically four shots of alcohol—all of which are roughly 40% ABV).
So, usually, the simpler the drink—and the less of it that you’re drinking—the better off your liver (and you!) will be. Here’s what to know about drinking different kinds of booze.
Beer
Beer can contain anywhere from 103 to 350 calories per 12 ounces. Craft beers often have a higher ABV than traditional macro-beers. And more alcohol means more calories.
For example, a 12-ounce beer with 9% ABV (typical for craft brews) has about 270 calories. But because craft breweries don’t have to list the calorie count on their beers, you can use this handy equation to estimate the number of calories in your beer: Multiply the ABV by 2.5, then multiply that by the number of ounces in your beer.
Vodka, tequila, and other spirits
Put this in the myth category. Tequila—as well as vodka, rum, and gin—all have zero grams of carbs, so they won’t raise your blood sugar if you drink them straight up. If you have diabetes, you should count your drink as two fat exchanges.

But don’t fall for the hype that choosing a tequila made from 100 percent agave changes the impact. All of the health attributes of agave (aka lower glycemic index, etc.) are gone once it’s been distilled into tequila. That said, choosing pure, agave tequila means you’ll typically skip unnecessary additives like caramel coloring. It’s also gluten-free.
Most hard seltzers are lower in alcohol, ranging from 4% to 6% ABV. But, they can contain added sugar.
Look for brands that offer very little sugar per serving. Otherwise, you’ll take in an overload of calories, mainly from the sweet stuff. Spiked seltzers, on the other hand, aren’t a bad option. Ideally, you want one that’s zero-calorie flavored sparkling water with booze added.
Wine
Most wines contain 120-130 calories per 5-ounce glass. But, the sugar content can vary. A glass of red table wine contains about 0.9 grams of sugar, according to the U.S. Department of Agriculture. Some white wines, like chardonnay, can contain 1.4 grams of sugar, and super-sweet dessert wines can have 7 grams.
Cocktails
Determining the calorie and sugar content of a cocktail is tricky, as it depends on what ingredients they contain. A simple vodka soda with seltzer and a squeeze of lime would be a low-calorie, low-sugar option.
But, sweet cocktails like a mai tai can have as much as 300 calories and loads of sugar. Creamy drinks like a White Russian or Piña Colada can clock in at more than 500 calories.
It’s always a good idea to opt for low-calorie mixers and avoid drinks overflowing with sugar, Dr. Gelb says.
You also need to drink plenty of water, too
Alcohol is a dehydrator. So, it’s crucial to drink plenty of water while you’re enjoying a beer or cocktail.

“Physicians recommend a one-for-one ratio, which is one 8-ounce glass of water for every alcoholic drink,” says Brian Fiani, D.O., attending neurosurgeon at Weill Cornell Medicine/NewYork-Presbyterian Hospital and vice chair of the American Osteopathic Association Bureau of Emerging Leaders.
Drinking alcohol can also irritate the stomach, worsen acid reflux, and contribute to gastritis, Dr. Kunza says. So, it’s a good idea to eat something before you drink or while you’re drinking.
How Drinking Too Much Affects Your Body
Having a few too many glasses of wine or overdoing it on the beer is OK every so often. Drinking too much of even low-calorie alcohol long-term can be detrimental to your health.
For one, it can affect the brain and spine. “Specifically, regarding the central nervous system, alcohol slows down the cerebral cortex process, which can lead to poor judgment,” Dr. Fiani says.
Long-term drinking can damage the brain’s frontal lobes, which can affect decision-making, memory, judgment, and impulses, he adds. It can also lead to degenerative disc disease of the spine and cause back pain.
Excessive alcohol intake over a long time period can cause a thiamine deficiency, which might lead to someone developing the brain disorder Wernicke-Korsakoff Syndrome, Fiani says. “This condition can cause irreversible mental confusion, loss of coordination, and memory problems similar to dementia.”
Overdoing it on alcohol can cause (or increase your risk for) a number of other health problems, like liver disease, pancreatitis, cancer, high blood pressure, anemia, GI problems, and other conditions.
Signs You Might Be Drinking Too Much
Excessive daily drinking could signal a drinking problem. “Individuals who can’t just have one drink would be a warning sign,” Dr. Gelb says.
The bottom line is: When alcohol or any substance use begins to interfere with your life, it’s problematic, says Lea McMahon, LPC, Ed.D., chief clinical officer at Symetria Recovery.
Mental health and addiction professionals use criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to assess substance use and how it affects someone’s life, she says. Patients are asked a series of questions, including:
Do you drink more than you mean to?
Do you want to stop but can’t?
Is drinking taking over your life?
Is drinking getting in the way of day-to-day activities?
Is drinking getting in the way of your relationships?
Do you need to drink more than you used to?
“The number of yes answers determines the degree to which one’s substance use is problematic,” McMahon says. For example, two or three yeses might signal a mild alcohol use disorder, four or five a moderate disorder, and six or more a severe disorder.
Health Experts Say This Is The One Type Of Carb You Should Stop Eating Because It Leads To Inflammation
Faith Geiger – December 11, 2022
woman holding jelly donut and to-go coffee cup outside
Ah, carbs—one of the most deviously delicious food groups. From pasta to bread to potato chips, who among us can resist the pull of these foods? It is worth noting that, fortunately, not all carbohydrates are bad for you. In fact, healthy carbs are an essential part of any balanced diet. However, there’s one specific variety that health experts agree you should avoid as much as possible if you care about your overall health: refined carbs.
To learn more about the affect an excessive intake of refined carbs can have on your body, we spoke to registered dietitian Trista Best from Balance One Supplements. She told us all about how these foods can lead to chronic inflammation, gut issues, weight gain, and more. Find all of her insight below!
Refined carbs
Refined carbs are a type of carb that have been stripped of their nutrients, making them a bad choice for your overall health. These include options like breakfast pastries, cereal, bagels, white bread, and more. “Foods made with refined carbohydrates are those that have undergone a processing step which removes portions of the grain’s nutrients and adds them back in synthetically,” Best tells us, explaining that “this process lessens beneficial nutrients and causes it to take a form that the body processes quickly.” And when your body can easily process the food you eat, it sets you up for a range of health issues, including blood sugar spikes, insulin resistance, increased cravings, a slower metabolism, and, ultimately, weight gain.
Weight gain isn’t the only risk posed by refined carbs and other processed foods, though. They can also be highly inflammatory and take a serious toll on your gut. As Best points out, refined carbs “wreak havoc on the body through gut dysbiosis and inflammation.” Gut dysbiosis is an imbalance of good and bad bacteria in your gut microbiome, which can lead to an array of digestive issues such as leaky gut, diarrhea, irritable bowel syndrome, and more, as your gut fights against the chronic inflammation.
