Deep below the surface of the ground in one of the driest parts of the country, there is a looming problem: The water is running out — but not the kind that fills lakes, streams and reservoirs.
[url=https://kra34c.cc]Площадка кракен[/url]
The amount of groundwater that has been pumped out of the Colorado River Basin since 2003 is enough to fill Lake Mead, researchers report in a study published earlier this week. Most of that water was used to irrigate fields of alfalfa and vegetables grown in the desert Southwest.
No one knows exactly how much is left, but the study, published in the journal Geophysical Research Letters, shows an alarming rate of withdrawal of a vital water source for a region that could also see its supply of Colorado River water shrink.
“We’re using it faster and faster,” said Jay Famiglietti, an Arizona State University professor and the study’s senior author.
In the past two decades, groundwater basins – or large, underground aquifers – lost more than twice the amount of water that was taken out of major surface reservoirs, Famiglietti’s team found, like Mead and Lake Powell, which themselves have seen water levels crash.
The Arizona State University research team measured more than two decades of NASA satellite observations and used land modeling to trace how groundwater tables in the Colorado River basin were dwindling. The team focused mostly on Arizona, a state that is particularly vulnerable to future cutbacks on the Colorado River.
Groundwater makes up about 35% of the total water supply for Arizona, said Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University, who was not directly involved in the study.
The study found groundwater tables in the Lower Colorado River basin, and Arizona in particular, have declined significantly in the last decade. The problem is especially pronounced in Arizona’s rural areas, many of which don’t have groundwater regulations, and little backup supply from rivers. With wells in rural Arizona increasingly running dry, farmers and homeowners now drill thousands of feet into the ground to access water.
Scientists don’t know exactly how much groundwater is left in Arizona, Famiglietti added, but the signs are troubling.
“We have seen dry stream beds for decades,” he said. “That’s an indication that the connection between groundwater and rivers has been lost.”

Despite prepping’s reputation as a form of doomerism, many left-wing preppers say they are not devoid of hope.
[url=https://tripscan.biz]tripscan top[/url]
Shonkwiler believes there will be an opportunity to create something new in the aftermath of a crisis. “It begins with preparedness and it ends with a better world,” he said.
Some also say there’s less tension between left- and right-wing preppers than people might expect. Bounds, the sociology professor, said very conservative preppers she met during her research contacted her during the Covid-19 pandemic to offer help.

There is a natural human solidarity that emerges amid disaster, Killjoy said. She recalls a cashier giving her a deep discount on supplies she was buying to take to Asheville post-Helene. “I have every reason to believe that that man is right-wing, and I do think that there is a transcending of political differences that happens in times of crisis,” she said.
As terrifying events pile up, from the wars in Ukraine and the Middle East to deadly extreme weather, it’s hard to escape the sense we live in a time of rolling existential crises — often a hair’s breadth from global disaster.
People are increasingly beginning to wonder whether their views on preppers have been misconceived, Mills said. “There is a bigger question floating in the air, which is: Are preppers crazy, or is everyone else?”
Killjoy has seen a huge change over the last five years in people’s openness to prepping. Those who used to make fun of her for her “go bag” are now asking for advice.
It’s not necessarily the start of a prepping boom, she said. “I think it is about more and more people adopting preparedness and prepper things into a normal life.”
Evidence already points this way. Americans stockpiled goods in advance of Trump’s tariffs and online sales of contraceptives skyrocketed in the wake of his election, amid concerns he would reduce access. Shows like “The Walking Dead,” meanwhile, have thrust the idea of prepping into popular culture and big box stores now sell prepping equipment and meal kits.
People are hungry to learn about preparedness, said Shonkwiler. “They have the understanding that the world as we knew it, and counted on it, is beginning to cease to be. … What we need to be doing now is figuring out how we can survive in the world that we’ve created.”

These preppers have ‘go bags,’ guns and a fear of global disaster. They’re also left-wing
[url=https://tripscan.biz]tripscan top[/url]
The day after President Donald Trump was elected in 2016, Eric Shonkwiler looked at his hiking bag to figure out what supplies he had. “I began to look at that as a resource for escape, should that need to happen,” he said.
He didn’t have the terminology for it at the time, but this backpack was his “bug-out bag” — essential supplies for short-term survival. It marked the start of his journey into prepping. In his Ohio home, which he shares with his wife and a Pomeranian dog, Rosemary, he now has a six-month supply of food and water, a couple of firearms and a brood of chickens. “Resources to bridge the gap across a disaster,” he said.

Margaret Killjoy’s entry point was a bleak warning in 2016 from a scientist friend, who told her climate change was pushing the global food system closer than ever to collapse. Killjoy started collecting food, water and generators. She bought a gun and learned how to use it. She started a prepping podcast, Live Like the World is Dying, and grew a community.
Prepping has long been dominated by those on the political right. The classic stereotype, albeit not always accurate, is of the lone wolf with a basement full of Spam, a wall full of guns, and a mind full of conspiracy theories.
Shonkwiler and Killjoy belong to a much smaller part of the subculture: They are left-wing preppers. This group is also preparing for a doom-filled future, and many also have guns, but they say their prepping emphasizes community and mutual aid over bunkers and isolationism.
In an era of barreling crises — from wars to climate change — some say prepping is becoming increasingly appealing to those on the left.
The roots of modern-day prepping in the United States go back to the 1950s, when fears of nuclear war reached a fever pitch.
The 1970s saw the emergence of the survivalist movement, which dwindled in the 1990s as it became increasingly associated with an extreme-right subculture steeped in racist ideology.
A third wave followed in the early 2000s, when the term “prepper” began to be adopted more widely, said Michael Mills, a social scientist at Anglia Ruskin University, who specializes in survivalism and doomsday prepping cultures. Numbers swelled following big disasters such as 9/11, Hurricane Katrina in 2005 and the 2008 financial crisis.
A watershed moment for right-wing preppers was the election of Barack Obama in 2008, Mills said. For those on the left, it was Trump’s 2016 election.
Preppers of all political stripes are usually motivated by a “foggy cloud of fear” rather than a belief in one specific doomsday scenario playing out, Mills said. Broad anxieties tend to swirl around the possibility of economic crises, pandemics, natural disasters, war and terrorism.
“We’ve hit every one of those” since the start of this century, said Anna Maria Bounds, a sociology professor at Queens College, who has written a book about New York’s prepper subculture. These events have solidified many preppers’ fears that, in times of crisis, the government would be “overwhelmed, under-prepared and unwilling to help,” she said.

‘Like wildfires underwater’: Worst summer on record for Great Barrier Reef as coral die-off sweeps planet
[url=https://tripscan.biz]tripscan[/url]
Great Barrier Reef, Australia
CNN
—
As the early-morning sun rises over the Great Barrier Reef, its light pierces the turquoise waters of a shallow lagoon, bringing more than a dozen turtles to life.
These waters that surround Lady Elliot Island, off the eastern coast of Australia, provide some of the most spectacular snorkeling in the world — but they are also on the front line of the climate crisis, as one of the first places to suffer a mass coral bleaching event that has now spread across the world.

The Great Barrier Reef just experienced its worst summer on record, and the US-based National Oceanic and Atmospheric Administration (NOAA) announced last month that the world is undergoing a rare global mass coral bleaching event — the fourth since the late 1990s — impacting at least 53 countries.
The corals are casualties of surging global temperatures which have smashed historical records in the past year — caused mainly by fossil fuels driving up carbon emissions and accelerated by the El Nino weather pattern, which heats ocean temperatures in this part of the world.
CNN witnessed bleaching on the Great Barrier Reef in mid-February, on five different reefs spanning the northern and southern parts of the 2,300-kilometer (1,400-mile) ecosystem.
“What is happening now in our oceans is like wildfires underwater,” said Kate Quigley, principal research scientist at Australia’s Minderoo Foundation. “We’re going to have so much warming that we’re going to get to a tipping point, and we won’t be able to come back from that.”

Bleaching occurs when marine heatwaves put corals under stress, causing them to expel algae from their tissue, draining their color. Corals can recover from bleaching if the temperatures return to normal, but they will perish if the water stays warmer than usual.
“It’s a die-off,” said Professor Ove Hoegh-Guldberg, a climate scientist at the University of Queensland in Australia and chief scientist at The Great Barrier Reef Foundation. “The temperatures got so warm, they’re off the charts … they never occurred before at this sort of level.”
The destruction of marine ecosystems would deliver an effective death sentence for around a quarter of all species that depend on reefs for survival — and threaten an estimated billion people who rely on reef fish for their food and livelihoods. Reefs also provide vital protection for coastlines, reducing the impact of floods, cyclones and sea level rise.
“Humanity is being threatened at a rate by which I’m not sure we really understand,” Hoegh-Guldberg said.

This company says its technology can help save the world. It’s now cutting 20% of its staff as Trump slashes climate funding
[url=https://trip-scan.top]трипскан сайт[/url]
Two huge plants in Iceland operate like giant vacuum cleaners, sucking in air and stripping out planet-heating carbon pollution. This much-hyped climate technology is called direct air capture, and the company behind these plants, Switzerland-based Climeworks, is perhaps its most high-profile proponent.
But a year after opening a huge new facility, Climeworks is straining against strong headwinds. The company announced this month it would lay off around 20% of its workforce, blaming economic uncertainties and shifting climate policy priorities.

“We’ve always known this journey would be demanding. Today, we find ourselves navigating a challenging time,” Climeworks’ CEOs Christoph Gebald and Jan Wurzbacher said in a statement.
This is particularly true of its US ambitions. A new direct air capture plant planned for Louisiana, which received $50 million in funding from the Biden administration, hangs in the balance as President Donald Trump slashes climate funding.
Climeworks also faces mounting criticism for operating at only a fraction of its maximum capacity, and for failing to remove more climate pollution than it emits.
The company says these are teething pains inherent in setting up a new industry from scratch and that it has entered a new phase of global scale up. “The overall trajectory will be positive as we continue to define the technology,” said a Climeworks spokesperson.
For critics, however, these headwinds are evidence direct air capture is an expensive, shiny distraction from effective climate action.

“Generally, if people were more informed about the average

(environmental) cost of generating a response, people would maybe start thinking, ‘Is it really necessary to turn myself into an action figure just because I’m bored?’ Or ‘do I have to tell ChatGPT jokes because I have nothing to do?’” Dauner said.
Additionally, as more companies push to add generative AI tools to their systems, people may not have much choice how or when they use the technology, Luccioni said.
“We don’t need generative AI in web search. Nobody asked for AI chatbots in (messaging apps) or on social media,” Luccioni said. “This race to stuff them into every single existing technology is truly infuriating, since it comes with real consequences to our planet.”

With less available information about AI’s resource usage, consumers have less choice, Ren said, adding that regulatory pressures for more transparency are unlikely to the United States anytime soon. Instead, the best hope for more energy-efficient AI may lie in the cost efficacy of using less energy.
“Overall, I’m still positive about (the future). There are many software engineers working hard to improve resource efficiency,” Ren said. “Other industries consume a lot of energy too, but it’s not a reason to suggest AI’s environmental impact is not a problem. We should definitely pay attention.”
