- “It’s true that both plants are not yet operating at the capacity we originally targeted,” said the Climeworks spokesperson. [url=https://tripscan.biz]tripskan[/url] “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. https://tripscan.biz tripscan top 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.”

- 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. https://trip-scan.top tripscan “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.

- Many left-wing preppers also have guns.

- Many left-wing preppers also have guns. [url=https://tripscan.biz]трипскан сайт[/url] Killjoy is open about the fact she owns firearms but calls it one of the least important aspects of her prepping. She lives in rural Appalachia and, as a transgender woman, says the way she’s treated has changed dramatically since Trump’s first election. For those on the left, guns are “for community and self-defense,” she said. Left-wing preppers consistently say the biggest difference between them and their right-wing peers is the rejection of “bunker mentality” — the idea of filling a bunker with beans, rice, guns and ammo and expecting to be able to survive the apocalypse alone. Shonkwiler gives an example of a right-wing guy with a rifle on his back, who falls down the stairs and breaks a leg. If he doesn’t have medical training and a community to help, “he’s going to die before he gets to enjoy all his freeze-dried food.” “People are our greatest asset,” Killjoy said. When Hurricane Helene carved a path of destruction through Asheville, North Carolina in 2024, Killjoy, who used to live in the city, loaded her truck with food and generators and drove there to help. https://tripscan.biz трипскан вход Inshirah Overton also subscribes to the idea of community. The attorney, who came to prepping after enduring Hurricane Irene in 2011, owns a half-acre plot of land in New Jersey where she grows food and has beehives. She stores fruit, vegetables and honey but also gives them to friends and neighbors. “My plan is to create a community of people who have a vested interest in this garden,” she said. At one point, Overton toyed with the idea of buying a “bug-out” property in Vermont, somewhere to escape to, but desire for community for her and her two daughters stopped her. In Vermont, “no one knows me and I’m just a random Black lady, and they’ll be like: ‘Oh, OK, right, sure. You live here? Sure. Here’s the barrel of my shotgun. Turn around.’” This focus on community may stem in part from left-wing preppers’ growing fears around the climate crisis, predicted to usher in far-reaching ecological, social and economic breakdown. It cannot be escaped by retreating to a bunker for a few weeks. As Trump guts weather agencies, pledges to unwind the Federal Emergency Management Administration and slashes climate funding — all while promising to unleash the fossil fuel industry — climate concerns are only coming into sharper focus. They’re top of mind for Brekke Wagoner, the creator and host of the Sustainable Prepping YouTube channel, who lives in North Carolina with her four children. She fears increasingly deadly summer heat and the “once-in-a-lifetime” storms that keep coming. Climate change “is just undeniable,” she said. Her prepping journey started during Trump’s first term. She was living in California and filled with fear that in the event of a big natural disaster, the federal government would simply not be there. Her house now contains a week’s worth of water, long-term food supplies, flashlights, backup batteries and a solar generator. “My goal is for our family to have all of our needs cared for,” she said, so in an emergency, whatever help is available can go to others. “You can have a preparedness plan that doesn’t involve a bunker and giving up on civilization,” she said.

- 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 войти[/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. https://tripscan.biz трипскан 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.”

- Study reveals how much energy AI uses to answer your questions

- Study reveals how much energy AI uses to answer your questions [url=https://tripscan.biz]трипскан вход[/url] Whether it’s answering work emails or drafting wedding vows, generative artificial intelligence tools have become a trusty copilot in many people’s lives. But a growing body of research shows that for every problem AI solves, hidden environmental costs are racking up. Each word in an AI prompt is broken down into clusters of numbers called “token IDs” and sent to massive data centers — some larger than football fields — powered by coal or natural gas plants. There, stacks of large computers generate responses through dozens of rapid calculations. The whole process can take up to 10 times more energy to complete than a regular Google search, according to a frequently cited estimation by the Electric Power Research Institute. https://tripscan.biz tripscan So, for each prompt you give AI, what’s the damage? To find out, researchers in Germany tested 14 large language model (LLM) AI systems by asking them both free-response and multiple-choice questions. Complex questions produced up to six times more carbon dioxide emissions than questions with concise answers. In addition, “smarter” LLMs with more reasoning abilities produced up to 50 times more carbon emissions than simpler systems to answer the same question, the study reported. “This shows us the tradeoff between energy consumption and the accuracy of model performance,” said Maximilian Dauner, a doctoral student at Hochschule Munchen University of Applied Sciences and first author of the Frontiers in Communication study published Wednesday. Typically, these smarter, more energy intensive LLMs have tens of billions more parameters — the biases used for processing token IDs — than smaller, more concise models. “You can think of it like a neural network in the brain. The more neuron connections, the more thinking you can do to answer a question,” Dauner said. What you can do to reduce your carbon footprint Complex questions require more energy in part because of the lengthy explanations many AI models are trained to provide, Dauner said. If you ask an AI chatbot to solve an algebra question for you, it may take you through the steps it took to find the answer, he said.

- The CO2 that is extracted from the water is run through a purification process that uses activated carbon in the form of charred coconut husks, and is then ready to be stored. [url=https://tripscan.biz]tripscan[/url] In a scaled up system, it would be fed into geological CO2 storage. Before the water is released, its acidity is restored to normal levels, making it ready to absorb more carbon dioxide from the air. “This discharged water that now has very low carbon concentrations needs to refill it, so it’s just trying to suck CO2 from anywhere, and it sucks it from the atmosphere,” says Halloran. “A simple analogy is that we’re squeezing out a sponge and putting it back.” While more tests are needed to understand the full potential of the technology, Halloran admits that it doesn’t “blow direct air capture out the water in terms of the energy costs,” and there are other challenges such as having to remove impurities from the water before releasing it, as well as the potential impact on ecosystems. But, he adds, all carbon capture technologies incur high costs in building plants and infrastructure, and using seawater has one clear advantage: It has a much higher concentration of carbon than air does, “so you should be able to really reduce the capital costs involved in building the plants.” https://tripscan.biz tripscan top Mitigating impacts One major concern with any system that captures carbon from seawater is the impact of the discharged water on marine ecosystems. Guy Hooper, a PhD researcher at the University of Exeter, who’s working on this issue at the SeaCURE site, says that low-carbon seawater is released in such small quantities that it is unlikely to have any effect on the marine environment, because it dilutes extremely quickly. However, that doesn’t mean that SeaCURE is automatically safe. “To understand how a scaled-up version of SeaCURE might affect the marine environment, we have been conducting experiments to measure how marine organisms respond to low-carbon seawater,” he adds. “Initial results suggest that some marine organisms, such as plankton and mussels, may be affected when exposed to low-carbon seawater.” To mitigate potential impacts, the seawater can be “pre-diluted” before releasing it into the marine environment, but Hooper warns that a SeaCURE system should not be deployed near any sensitive marine habitats. There is rising interest in carbon capture from seawater — also known as Direct Ocean Capture or DOC — and several startups are operating in the field. Among them is Captura, a spin off from the California Institute of Technology that is working on a pilot project in Hawaii, and Amsterdam-based Brineworks, which says that its method is more cost-effective than air carbon capture. According to Stuart Haszeldine, a professor of Carbon Capture and Storage at the University of Edinburgh, who’s not involved with SeaCURE, although the initiative appears to be more energy efficient than current air capture pilot tests, a full-scale system will require a supply of renewable energy and permanent storage of CO2 by compressing it to become a liquid and then injecting it into porous rocks deep underground. He says the next challenge is for SeaCURE to scale up and “to operate for longer to prove it can capture millions of tons of CO2 each year.” But he believes there is huge potential in recapturing carbon from ocean water. “Total carbon in seawater is about 50 times that in the atmosphere, and carbon can be resident in seawater for tens of thousands of years, causing acidification which damages the plankton and coral reef ecosystems. Removing carbon from the ocean is a giant task, but essential if the consequences of climate change are to be controlled,” he says.
