  Study reveals how much energy AI uses to answer your questions
  tripscan top
  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.

  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.

  Beirut, Lebanon
  CNN
  —
  A deadly Israeli airstrike on Hezbollah’s stronghold in southern Beirut on Friday has left over a dozen people dead, including a high-ranking Hezbollah commander, sharply escalating the conflict between the two sides and raising fears of all-out war.
  
  Senior Hezbollah commander Ibrahim Aqil, part of Hezbollah’s elite Radwan Force, was assassinated along with “about 10” other commanders, Israel Defense Forces (IDF) spokesperson Daniel Hagari said, accusing them of planning to raid and occupy communities in Galilee in northern Israel.
  
  Hezbollah confirmed Aqil’s death on Friday, saying he was killed “following a treacherous Israeli assassination operation on 09/20/2024 in the southern suburbs of Beirut.”
  
  According to Hagari, the targeted commanders were “underground underneath a residential building in the heart of the Dahiyeh neighborhood, using civilians as a human shield” at the time of the attack.
  
  Lebanon’s health ministry said at least 14 people were killed and 66 others injured in the airstrike, which leveled a multistory building in a densely populated neighborhood.
  
  Aqil had a $7 million bounty on his head from the United States for his suspected involvement in the 1983 strike on the US Embassy in Beirut, which killed 63 people, as well as the bombing of the Beirut Marine barracks, which killed 241 US personnel later that year.
  
  A CNN team on the ground in Beirut saw a frantic effort to rescue people from underneath the rubble and rush the wounded to hospital. Witnesses said nearby buildings shook for nearly half an hour after the strike, which the IDF said it had carried out at around 4 p.m. local time.
  
  
  A week of surprise attacks
  Friday’s strike marked the fourth consecutive day of surprise attacks on Beirut and other sites across the country, even as Israeli forces continued deadly strikes and operations in Gaza and the occupied West Bank.
  
  The first major attack against Hezbollah this week came Tuesday afternoon when pagers belonging to the militant groups’ members exploded near-simultaneously. The pagers had been used by Hezbollah to communicate after the group’s leader, Hassan Nasrallah, encouraged members to switch to low-tech devices to prevent more of them from being assassinated.
  
  Almost exactly 24 hours later, Lebanon was rocked by a second wave of explosions, after Hezbollah walkie-talkies detonated in Beirut and the south of the country on Wednesday.
  
  At least 37 people were killed, including some children, and more than 3,000 were injured in the twin attacks.
  
  In a United Nations Security Council meeting on Friday, UN human rights chief Volker Turk on Friday warned that the detonation of communication devices could violate international human rights law.
  
  Lebanese Foreign Minister Abdallah Bou Habib and Israeli Ambassador to the UN Danny Danon clashed at the heated meeting, with Bou Habib calling on the council to condemn Israel’s actions and Danon slamming the Lebanese envoy for not mentioning Hezbollah.

  ‘Like wildfires underwater’: Worst summer on record for Great Barrier Reef as coral die-off sweeps planet
  tripscan top
  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

  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.

  Despite prepping’s reputation as a form of doomerism, many left-wing preppers say they are not devoid of hope.
  [url=https://tripscan.biz]tripskan[/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.”

  Many left-wing preppers also have guns.
  [url=https://tripscan.biz]tripscan войти[/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.

  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.
