      Scientists Predict Most Extensive Coral Bleaching Event on Record

      by

      Rising sea temperatures around the planet have caused a bleaching event that is expected to be the most extensive on record.The world’s coral reefs are in the throes of a global bleaching event caused by extraordinary ocean temperatures, the National Oceanic and Atmospheric Administration and international partners announced Monday.It is the fourth such global event on record and is expected to affect more reefs than any other. Bleaching occurs when corals become so stressed that they lose the symbiotic algae they need to survive. Bleached corals can recover, but if the water surrounding them is too hot for too long, they die.Coral reefs are vital ecosystems: limestone cradles of marine life that nurture an estimated quarter of ocean species at some point during their life cycles, support fish that provide protein for millions of people and protect coasts from storms. The economic value of the world’s coral reefs has been estimated at $2.7 trillion annually.For the last year, ocean temperatures have been off the charts.“This is scary, because coral reefs are so important,” said Derek Manzello, the coordinator of NOAA’s Coral Reef Watch program, which monitors and predicts bleaching events.The news is the latest example of climate scientists’ alarming predictions coming to pass as the planet heats. Despite decades of warnings from scientists and pledges from leaders, nations are burning more fossil fuels than ever and greenhouse gas emissions continue to rise.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      PFAS ‘Forever Chemicals’ Are Pervasive in Water Worldwide, Study Finds

      by

      A global survey found harmful levels even in water samples taken far any obvious source of contamination.They’re in makeup, dental floss and menstrual products. They’re in nonstick pans and takeout food wrappers. Same with rain jackets and firefighting equipment, as well as pesticides and artificial turf on sports fields.They’re PFAS: a class of man-made chemicals called per- and polyfluoroalkyl substances. They are also called “forever chemicals” because the bonds in their chemical compounds are so strong they don’t break down for hundreds to thousands of years, if at all.They’re also in our water.A new study of more than 45,000 water samples around the world found that about 31 percent of groundwater samples tested that weren’t near any obvious source of contamination have PFAS levels considered harmful to human health by the Environmental Protection Agency. About 16 percent of surface water samples tested, which were also not near any known source, have similarly hazardous PFAS levels.This finding “sets off alarm bells,” said Denis O’Carroll, a professor of civil and environmental engineering at the University of New South Wales and one of the authors of the study, which was published on Monday in Nature Geoscience. “Not just for PFAS, but also for all the other chemicals that we put out into the environment. We don’t necessarily know their long-term impacts to us or the ecosystem.”High levels of exposure to some PFAS chemicals have been linked to higher cholesterol, liver and immune system damage, hypertension and pre-eclampsia during pregnancy, as well as kidney and testicular cancer.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      They Came From Outer Space. Now, They’re Going Into Hiding.

      by

      Rising temperatures in Antarctica are making meteorites sink out of view before researchers can collect them.If you’re looking for meteorites, here’s a tip: Go south. All the way south. And do it soon.In some parts of Antarctica, there’s a good chance that what looks like a regular old rock could actually be a chunk of an asteroid, the moon, or even Mars. Roughly 60 percent of all known meteorites have been collected there.But scientific sleuthing for such extraterrestrial material, which can shed light on how the solar system formed billions of years ago, will probably get more difficult in Antarctica in the coming decades. That’s because, as temperatures rise, thousands of meteorites will sink into the continent’s ice and disappear from sight every year, according to a new study published on Monday.Antarctica’s meteorite largess isn’t because more extraterrestrial stuff is falling there, Cari Corrigan, a geologist at the Smithsonian Institution and a curator of the National Museum of Natural History’s meteorite collection, said.Rather, meteorites simply tend to be more visible on the Antarctic ice sheet than they would be, say, in your backyard. “Your eye can pick out a dark rock on a white surface super easily,” said Dr. Corrigan, who was not involved in the new research.The continent also has places known as blue-ice areas, that are particularly good for finding meteorites. These regions are often near geographic obstructions like mountains, where layers of ice tend to pile up and strong winds continuously erode the surface. Those conditions are ideal for concentrating, and revealing, meteorites that have fallen over millenniums.But warming temperatures could send many meteorites out of sight. In recent years, researchers have spotted specimens in Antarctica that have been partially encrusted in ice rather than sitting exposed on the surface.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      The Last Coal-Fired Power Plants in New England Are to Close

      by

      The company that owns the Merrimack and Schiller stations in New Hampshire plans to turn them into solar farms and battery storage for offshore wind.The last two coal-fired power plants in New England are set to close by 2025 and 2028, ending the use of a fossil fuel that supplied electricity to the region for more than 50 years.The decision to close the Merrimack and Schiller stations, both in New Hampshire, makes New England the second region in the country, after the Pacific Northwest, to stop burning coal.Environmentalists waged a five-year legal battle against the New Hampshire plants, saying that the owner had discharged warm water from steam turbines into a nearby river without cooling it first to match the natural temperature.In a settlement reached on Wednesday with the Sierra Club and the Conservative Law Foundation, Granite Shore Power, the owner of the plants, agreed that Schiller would not run after Dec. 31, 2025 and that Merrimack would cease operations no later than June 2028.“This announcement is the culmination of years of persistence and dedication from so many people across New England,” said Gina McCarthy, a former national climate adviser to President Biden and former administrator of the Environmental Protection Agency during the Obama administration who is now a senior adviser at Bloomberg Philanthropies, which supports efforts to phase out coal.“I’m wicked proud to live in New England today and be here,” Ms. McCarthy said. “Every day, we’re showing the rest of the country that we will secure our clean energy future without compromising.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      A New Law Would Remove Many Architectural Protections in Miami Beach

      by

      Lawmakers say preservationists held too much power over decisions on whether buildings should be demolished and what should be allowed to replace them.The oceanfront Eden Roc Hotel is an icon of Miami Modernist architecture, a style that epitomized the postwar glamour and grandeur of Miami Beach. Two turquoise panels wrap the white facade. The oval canister perched atop the building resembles a cruise ship’s funnel. Crooners like Frank Sinatra, Harry Belafonte, and Sammy Davis, Jr., stayed and played there.But a new Florida law could make it easier for hotels like the Eden Roc and other architectural icons along Miami Beach’s coastline to be demolished. The battle pits the pressures of development and climate change against the benefits of historical preservation, in a city that has long paved over its past and prizes the new, shiny, and glitzy.Supporters say the law addresses environmental and safety challenges of aging properties after the deadly 2021 collapse of the Champlain Towers South condo. But critics believe the legislation is a pretext to facilitate the demolition of historical buildings — ones that give Miami Beach its distinct look — to make way for high-rise luxury condos.The new law effectively strips Miami Beach Historic Preservation Board of its long-held power to say whether historic structures can be demolished and, if a structure is knocked down, to ensure that at least some elements of its design are preserved or replicated. “Let’s just bulldoze the past — that’s their idea,” said Daniel Ciraldo, the executive director of the nonprofit Miami Design Preservation League. “I don’t think we’ve seen such an attack on our local controls since the 1980s, back when the city first started to do historic preservation.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      How the New E.P.A. Rules Affect Toyota and Their Hybrid Cars

      by

      The auto giant lobbied hard against tougher pollution rules. This week, the E.P.A.’s new rules proved favorable to hybrid technology, an area that Toyota dominates.The breakfast at Toyota’s annual dealership gathering in Las Vegas last fall was an exclusive, invite-only affair, where attendees were told to cover their cellphone cameras with red stickers.Speaking was Stephen Ciccone, Toyota’s top lobbyist. He said the industry was facing an existential crisis — not because of the economy or fuel prices, but because of stronger tailpipe pollution limits being proposed in the United States. The rules were “bad for the country, bad for the consumer, and bad for the auto industry,” he said, according to a memo he later circulated among Toyota dealerships that was reviewed by The New York Times.“For more than two years, Toyota and our dealer partners have stood alone in the fight against unrealistic BEV mandates,” he wrote, using the acronym for battery-electric vehicles. “We have taken a lot of hits from environmental activists, the media, and some politicians. But we have not — and we will not — back down.”On Wednesday, the Environmental Protection Agency finalized tailpipe emissions rules that require car makers to meet tough new average emissions limits. The rules are some of the most significant aimed at fighting climate change in United States history.But the rules relaxed major elements of an earlier, more stringent proposal. In particular, the final regulations were favorable to hybrid cars, those that run both on gasoline and electricity — giving a bigger role to a market that Toyota dominates.Toyota, it appeared, had come out on top.Once a leader in clean cars, Toyota has cemented its role as the voice of caution against electrifying the auto industry too quickly, using its lobbying and public relations muscle to oppose a rapid shift that experts say is critical to fighting climate change.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Sixteen States Sue Biden Administration Over Gas Permit Pause

      by

      President Biden halted approvals for new exports of liquefied natural gas to study its effect on the climate, national security and the economy. Major oil- and gas-producing states are angry.Louisiana and 15 other Republican-led states sued the Biden administration on Thursday over its decision to temporarily stop approving new permits for facilities that export liquefied natural gas.The lawsuit contends that the Biden administration acted illegally when it decided in January to pause the approvals so it could study how gas exports affect climate change, the economy and national security.Filed in the United States District Court for the Western District of Louisiana, the lawsuit asks a judge to end the pause, arguing that the White House had flouted the regulatory process and instead taken action “by fiat.”“There is no legal basis for the pause,” Elizabeth B. Murrill, the attorney general of Louisiana, which led the legal challenge, said in an interview.Ms. Murrill, who referred to the pause as a ban, said halting permits for any amount of time would hurt states’ economies and would have significant long-term consequences abroad by restricting supplies of gas from the United States to Europe.The United States is the world’s top exporter of natural gas. Liquefied natural gas is a gas that has been cooled to a liquid state to allow for shipping and storage. Even with the pause, the country is still on track to nearly double its export capacity by 2027 because of projects already permitted and under construction. But any expansions beyond that are now in doubt.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      In Paris, the Olympics Clean Up Their Act

      by

      How do you produce a global sporting event, with millions of people swooping down on one city, in the age of global warming?That is the test for the Paris Olympics this summer.The organizers say they’re putting the games on a climate diet. These Olympics, they say, will generate no more than half the greenhouse gas emissions of recent Olympics. That means tightening the belt on everything that produces planet-warming emissions: electricity, food, buildings, and transportation, including the jet fuel that athletes and fans burn traveling the world to get there.An event that attracts 10,500 athletes and an estimated 15 million spectators is, by definition, going to have an environmental toll. And that has led those who love the games but hate the pollution to suggest that the Olympics should be scattered around the world, in existing facilities, to eliminate the need for so much new construction and air travel. That’s why Paris is being watched so closely.It is making more space for bikes and less for cars. It’s doing away with huge, diesel-powered generators, a fixture of big sporting events. It’s planning guest menus that are less polluting to grow and cook than typical French fare: more plants, less steak au poivre. Solar panels will float, temporarily, on the Seine.But the organizers’ most significant act may be what they are not doing: They aren’t building. At least, not as much.Construction of bike lanes at Boulevard Haussman.Yulia Grigoryants for The New York TimesWe are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
