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

    “AI expends a lot of energy being polite especially if the user is polite saying ‘please’ and ‘thank you’” трипскан сайт 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 tripscan войти 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.

    “Generally if people were more informed about the average tripscan top 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.” https://tripscan.biz трип скан 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.” Sign up for CNN’s Life But Greener newsletter.

    “We’re asking everyone to take it slow avoid driving through standing water and use alternate routes when possible” Rosenlund urged. трипскан сайт Rainfall in Grand Island began Wednesday afternoon but the intensity picked up quickly after dark falling at more than an inch per hour at times. A total of 6.41 inches of rain fell by midnight which made it the rainiest June day and the second rainiest day of any month in the city’s 130-year history of weather records. The National Weather Service issued a flash flood emergency — the most severe form of flood warning — at 11:45 p.m. CDT Wednesday for Grand Island that continued for several hours into Thursday morning continuously warning of “extensive flash flooding.” https://tripscan.biz tripscan Multiple rounds of heavy storms tracked over the area late Wednesday into early Thursday morning and ultimately dumped record amounts of rainfall. A level 2-of-4 risk of flooding rainfall was in place for Grand Island at the time according to the Weather Prediction Center. More than a month’s worth of rain – nearly 4.5 inches – fell in only three hours between 10 p.m. CDT Wednesday and 1 a.m. CDT Thursday. Rainfall of this intensity would only be expected around once in 100 years according to National Oceanic and Atmospheric Administration data. Climate change is making heavy rainfall events heavier. As the world warms due to fossil fuel pollution a warmer atmosphere is able to soak up more moisture like a sponge only to wring it out in heavier bursts of rain. Hourly rainfall rates have intensified in nearly 90 of large US cities since 1970 a recent study found.

    Despite prepping’s reputation as a form of doomerism many left-wing preppers say they are not devoid of hope. tripscan 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 tripscan 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.”

    Many left-wing preppers also have guns. трип скан 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.
