These preppers have ‘go bags,’ guns and a fear of global disaster. They’re also left-wing
трипскан
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.

This company says its technology can help save the world. It’s now cutting 20% of its staff as Trump slashes climate funding
трипскан сайт
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.

‘Extraordinary rainstorm’ floods Nebraska city, triggers water rescues
трипскан
An entire June’s worth of rain fell in just a few hours over Grand Island, Nebraska, Wednesday night, triggering life-threatening flash flooding that inundated neighborhoods, stranded motorists and forced water rescues.

Crews have responded to dozens of calls to assist motorists stuck in flooded roads since torrential rain began Wednesday night, according to Spencer Schubert, the city’s communications manager. The flooding has also displaced an unspecified number of residents from their homes.

“At this time we have no injuries to report,” Schubert said early Thursday morning, noting some rescues were ongoing.

Torrential rain caused sewers to back up into several homes and sent floodwater running into basements, according to a Thursday news release from the city. Some affected residents took shelter at local hotels or with friends and family.

“This was an extraordinary rainstorm and is very similar to the historic rains seen in the 2005 floods,” Jon Rosenlund, the city’s emergency director said. “We will be actively monitoring rivers, creeks and other drainage areas over the next few days for future flooding issues.”

Flooding in 2005 turned streets into rivers in Grand Island. At one point, the city tore up a major road to open up a channel to drain flooding away from homes, CNN affiliate KHGI reported.

The central Nebraskan city is home to around 53,000 people and is about 130 miles southwest of Omaha. The rain came to an end around sunrise Thursday, but the danger remains, with a flood warning in effect until 7 p.m. CDT.

A nuclear fusion power plant prototype is already being built outside Boston. How long until unlimited clean energy is real?
гей член
In an unassuming industrial park 30 miles outside Boston, engineers are building a futuristic machine to replicate the energy of the stars. If all goes to plan, it could be the key to producing virtually unlimited, clean electricity in the United States in about a decade.

The donut-shaped machine Commonwealth Fusion Systems is assembling to generate this energy is simultaneously the hottest and coldest place in the entire solar system, according to the scientists who are building it.

It is inside that extreme environment in the so-called tokamak that they smash atoms together in 100-million-degree plasma. The nuclear fusion reaction is surrounded by a magnetic field more than 400,000 times more powerful than the Earth’s and chilled with cryogenic gases close to absolute zero.

The fusion reaction — forcing two atoms to merge — is what creates the energy of the sun. It is the exact opposite of what the world knows now as “nuclear power” — a fission reaction that splits atoms.

Nuclear fusion has far greater energy potential, with none of the safety concerns around radioactive waste.

SPARC is the tokamak Commonwealth says could forever change how the world gets its energy, generating 10 million times more than coal or natural gas while producing no planet-warming pollution. Fuel for fusion is abundant, derived from deuterium, found in seawater, and tritium extracted from lithium. And unlike nuclear fission, there is no atomic waste involved.

The biggest hurdle is building a machine powerful and precise enough to harness the molten, hard-to-tame plasma, while also overcoming the net-energy issue – getting more energy out than you put into it.
“Basically, what everybody expects is when we build the next machine, we expect it to be a net-energy machine,” said Andrew Holland, CEO of the Fusion Industry Association, a trade group representing fusion companies around the globe. “The question is, how fast can you build that machine?”

Commonwealth’s timeline is audacious: With over $2 billion raised in private capital, its goal is to build the world’s first fusion-fueled power plant by the early 2030s in Virginia.

“It’s like a race with the planet,” said Brandon Sorbom, Commonwealth’s chief science officer. Commonwealth is racing to find a solution for global warming, Sorbom said, but it’s also trying to keep up with new power-hungry technologies like artificial intelligence. “This factory here is a 24/7 factory,” he said. “We’re acutely aware of it every minute of every hour of every day.”

“It’s true that both plants are not yet operating at the capacity we originally targeted,” said the Climeworks spokesperson.

“Like all transformative innovations, progress is iterative, and some steps may take longer than anticipated,” they said.

The company’s prospective third plant in Louisiana aims to remove 1 million tons of carbon a year by 2030, but it’s uncertain whether construction will proceed under the Trump administration.

A Department of Energy spokesperson said a department-wide review was underway “to ensure all activities follow the law, comply with applicable court orders and align with the Trump administration’s priorities.” The government has a mandate “to unleash ‘American Energy Dominance’,” they added.

Direct air capture’s success will also depend on companies’ willingness to buy carbon credits.

Currently companies are pretty free to “use the atmosphere as a waste dump,” said Holly Buck, assistant professor of environment and sustainability at the University at Buffalo. “This lack of regulation means there is not yet a strong business case for cleaning this waste up,” she told CNN.

Another criticism leveled at Climeworks is its failure to offset its own climate pollution. The carbon produced by its corporate activities, such as office space and travel, outweighs the carbon removed by its plants.

The company says its plants already remove more carbon than they produce and corporate emissions “will become irrelevant as the size of our plants scales up.”

Some, however, believe the challenges Climeworks face tell a broader story about direct air capture.

This should be a “wake-up call,” said Lili Fuhr, director of the fossil economy program at the Center for International Environmental Law. Climeworks’ problems are not “outliers,” she told CNN, “but reflect persistent technical and economic hurdles faced by the direct air capture industry worldwide.”

“The climate crisis demands real action, not speculative tech that overpromises and underdelivers.” she added.

Some of the Climeworks’ problems are “related to normal first-of-a-kind scaling challenges with emerging complex engineering projects,” Buck said.

But the technology has a steep path to becoming cheaper and more efficient, especially with US slashing funding for climate policies, she added. “This kind of policy instability and backtracking on contracts will be terrible for a range of technologies and innovations, not just direct air capture.”

Direct air capture is definitely feasible but its hard, said MIT’s Buck. Whether it succeeds will depend on a slew of factors including technological improvements and creating markets for carbon removals, he said.

“At this point in time, no one really knows how large a role direct air capture will play in the future.”

‘Like wildfires underwater’: Worst summer on record for Great Barrier Reef as coral die-off sweeps planet
трипскан вход
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.
https://tripscan.biz
tripscan
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.

“AI expends a lot of energy being polite, especially if the user is polite, saying ‘please’ and ‘thank you,’”
трипскан
Dauner explained. “But this just makes their responses even longer, expending more energy to generate each word.”

For this reason, Dauner suggests users be more straightforward when communicating with AI models. Specify the length of the answer you want and limit it to one or two sentences, or say you don’t need an explanation at all.

Most important, Dauner’s study highlights that not all AI models are created equally, said Sasha Luccioni, the climate lead at AI company Hugging Face, in an email. Users looking to reduce their carbon footprint can be more intentional about which model they chose for which task.

“Task-specific models are often much smaller and more efficient, and just as good at any context-specific task,” Luccioni explained.
https://tripscan.biz
tripskan
If you are a software engineer who solves complex coding problems every day, an AI model suited for coding may be necessary. But for the average high school student who wants help with homework, relying on powerful AI tools is like using a nuclear-powered digital calculator.

Even within the same AI company, different model offerings can vary in their reasoning power, so research what capabilities best suit your needs, Dauner said.

When possible, Luccioni recommends going back to basic sources — online encyclopedias and phone calculators — to accomplish simple tasks.

Why it’s hard to measure AI’s environmental impact
Putting a number on the environmental impact of AI has proved challenging.

The study noted that energy consumption can vary based on the user’s proximity to local energy grids and the hardware used to run AI models.
That’s partly why the researchers chose to represent carbon emissions within a range, Dauner said.

Furthermore, many AI companies don’t share information about their energy consumption — or details like server size or optimization techniques that could help researchers estimate energy consumption, said Shaolei Ren, an associate professor of electrical and computer engineering at the University of California, Riverside who studies AI’s water consumption.

“You can’t really say AI consumes this much energy or water on average — that’s just not meaningful. We need to look at each individual model and then (examine what it uses) for each task,” Ren said.

One way AI companies could be more transparent is by disclosing the amount of carbon emissions associated with each prompt, Dauner suggested.
