By Lisa Friedman  and  Maxine Joselow , The New York Times.  Excerpt: The Environmental Protection Agency announced on Wednesday that it would delay a requirement that the oil and gas industry limit emissions of methane, a powerful planet-warming gas. Under the requirement, which dates to the Biden administration, oil and gas companies were supposed to start this year reducing the amount of methane they release into the atmosphere. Instead, the Trump administration is giving them until January 2027 and is considering repealing the measure altogether. The move dealt a blow to any remaining effort by the United States to slow Earth’s dangerous warming. It came after the Trump administration  boycotted the United Nations climate summit  this month, the first time that the United States was not present since the annual meetings began 30 years ago....  Full article at https://www.nytimes.com/2025/11/26/climate/epa-delays-methane-oil-gas.html .

By Paul Voosen , Science.  Excerpt: It seems an easy climate solution, almost too good to be true. Greenhouse gas emissions from airplanes are stubbornly difficult to reduce—batteries cannot power a jumbo jet. But in the past few years, scientists and industry have seized on a way to trim airplanes’ climate footprint by limiting the clouds they leave behind. Jet contrails, when they turn into long-lived clouds, trap significant amounts of heat that would otherwise escape Earth—three times more than the carbon dioxide (CO 2 ) emitted by the engines, some studies have suggested. In theory, tweaking flight routes to avoid creating these clouds could slash aviation’s toll on the climate....  Full article at https://www.science.org/content/article/airplane-contrails-may-not-be-climate-villain-once-feared .

As a Navajo citizen and tribal energy expert who used to work in the federal government, he saw it as the ultimate test of how far energy infrastructure had come. Stop by stop, his plans came together until North Dakota, where a dearth of chargers seemed to prevent a Midwest crossing. Then, he spotted it: a level-2 charger at Sitting Bull College on the Standing Rock Reservation. It was more than a lucky break. Over the past three years, Standing Rock has installed chargers across the reservation as part of the Electric Nation project, a regional effort to create an intertribal charging network.

By Brad Plumer , The New York Times.  Excerpt: Global fossil fuel emissions are on track to soar to record highs in 2025 and show no signs of declining overall, although there are indications of a recent slowdown in China’s emissions, researchers said on Wednesday. This year, nations are projected to emit roughly 38.1 billion tons of planet-warming carbon dioxide by burning oil, gas and coal for energy and by manufacturing cement, according to  data from the Global Carbon Project . Those sources are the largest contributors to human-caused climate change. The total is roughly 1.1 percent more than the world emitted in 2024. Not everywhere saw a large increase. Emissions appear to have stayed nearly flat in China and Europe, but rose significantly in the United States and much of the rest of the world. ...A relatively small number of countries account for most of the world’s emissions, with China responsible for 32 percent, the United States at 13 percent, India at 8 percent an...

By Colleen Howe , Reuters.  Excerpt: BEIJING, Nov 12 (Reuters) - China's energy administration said on Wednesday that it will push renewable energy use beyond the power sector over the next five years, aiming to better absorb the country's booming wind and solar output. Provinces and power producers should help local governments to build up their industrial bases for green hydrogen, green ammonia, green methanol, and sustainable aviation fuel during the next five-year plan from 2026-2030, the National Energy Administration (NEA) said in its opinion document on integrating new energy. Green hydrogen ... can serve as a low-carbon fuel for heavy industry and transport, power industrial processes or vehicles, and as a feedstock for ammonia and methanol, which are used in fertilisers, shipping and elsewhere. The department encouraged coastal areas to explore using offshore wind to produce hydrogen, a still nascent production method. The document also called for using renewables to p...

By Somini Sengupta  and  Brad Plumer ,  The New York Times.  ' Excerpt: As the United States  torpedoes climate action  and Europe  struggles to realize its green ambitions , a surprising shift is taking hold in many large, fast-growing economies where a majority of the world’s people live. Countries like Brazil, India, and Vietnam are rapidly expanding solar and wind power. Poorer countries like Ethiopia and Nepal are leapfrogging over gasoline-burning cars to battery-powered ones. Nigeria, a petrostate, plans to  build its first solar-panel manufacturing plant . Morocco is creating a battery hub to supply European automakers. Santiago, the capital of Chile, has electrified more than half of its bus fleet in recent years. Key to this shift is the world’s new renewable energy superpower: China.

But he has also deftly led the I.E.A. through a decade during which energy has re-emerged as a geopolitical weapon. The debate over how to address climate change is upending economic and diplomatic relations around the world — right as the Trump administration works to reverse a global push for a transition to renewable energy by producing, consuming and exporting as much fossil fuel as it can. Mr. Birol, for his part, has repeatedly offered the fossil fuel industry a kind of “adapt or fail” warning, particularly as solar power grows at a pace that even the I.E.A. underestimated. ...The organization’s members, mostly Western countries, have increasingly turned to it for guidance, even if the I.E.A. has occasionall...

By Sachi Kitajima Mulkey , The New York Times.  Excerpt: Hurricane Melissa’s path through the Caribbean last month was made more violent by climate change, according to a scientific analysis released Thursday. Researchers from the group World Weather Attribution found that the storm had 7 percent stronger wind speeds than a similar one in a world that has not been warmed by the burning of fossil fuels. They also found the rate of rainfall inside the eyewall of the storm was 16 percent more intense. Melissa made landfall as a Category 5 storm in Jamaica on Oct. 28 with wind speeds of 185 miles per hour, collapsing buildings and knocking out internet to most of the island. It continued on to Cuba as a Category 3 storm, forcing hundreds to evacuate, and pummeled Haiti with catastrophic flooding. Dozens of people in hard-hit areas have died.

By Hannah Richter , Science.  Excerpt: In 2022, something shocking happened to the Hektoria Glacier, a small river of ice that slips into the sea near the tip of the Antarctic Peninsula. Over 16 months, it retreated by 25 kilometers, and it lost a whopping 8 kilometers in just two of those months—the fastest glacial retreat in the modern record. Now, after  a forensic analysis of the event reported today in  Nature Geoscience , researchers say they have identified the worrisome mechanisms behind it: a combination of glacial earthquakes and a swath of thinned ice popping afloat and breaking apart in a geological instant. If the same processes were to occur at larger Antarctic glaciers, they could rapidly accelerate the retreat of ice sheets and raise global sea levels, says Jeremy Bassis, a glaciologist at the University of Michigan. The study is “telling us that those worst-case scenarios are maybe not as implausible as some people might have thought.” ...[Jeremy] Bassis ...

By Rebecca Owen , Eos/AGU.  Excerpt: Tropical forests are biodiversity hot spots; preserving them is a crucial part of global efforts to mitigate the effects of climate change. When these verdant ecosystems are destroyed, they release  millions  of metric tons of carbon dioxide each year, emissions numbers second only to those driven by fossil fuel consumption. A host of international efforts have emerged to help curb tropical forest loss. The Reducing Emissions from Deforestation and Forest Degradation in Developing Countries ( REDD+ ) program, established in 2005, is a United Nations–supported initiative for countries to sustainably manage and conserve forested land to reduce greenhouse gas emissions. Countries receive financial incentives to preserve and maintain their forests—compensation intended to make forests more valuable intact than cut down. There are more than 350 REDD+ projects worldwide, and in many project locations,  habitats have been protected , and...

By Taylor Mitchell Brown , Science.  Excerpt: About 2200 years ago, a wealthy Han soldier was entombed in a hillside grave on the frontier of the expanding Han Dynasty, in what is now western China. His tomb was filled with gold coins and emblazoned with ornate calligraphy. But what most interested Bao Yang at the Chinese Academy of Sciences (CAS) and head of its Tree-Ring Laboratory was the wood of his coffin. For dendrochronologists like Yang, coffin wood can be a critical source of tree rings, which can help scientists date sites—sometimes to precise calendar years—and offer details about the region’s environment and climate during the tree’s lifetime. The thickness of rings from the Han soldier’s pine coffin and hundreds of others like it, for example,  revealed that from 270 B.C.E. to 77 C.E. average humidity levels were 18% to 34% higher than today’s, which may have allowed the western Han to expand westward  into what before—and is again today—a barren desert.

By Science Advisor.  Excerpt: Researchers have declared  southern Florida’s  Acropora  coral colonies functionally extinct . The death knell for two reef-building species, elkhorn and staghorn, was the 2023 marine heatwave that brought temperatures above 31°C for almost 6 weeks. The event was the ninth mass coral mortality event for the region since 1987. “ This ecosystem is forever transformed ,” lead author Ross Cunning told  Nature . Conservation for these species “needs to fundamentally change.” Acropora  have made Florida and the Caribbean their home for the past 250,000 to 500,000 years. During the heatwave, they bleached in 98% to 100% of their southern Florida range, a process whereby the corals lose the symbiotic algae that feed them and give them color. Previously, scientists had attempted to reintroduce the corals in areas where they had declined. But with the reintroduced organisms now dead, the authors say that efforts must turn to breeding mor...

By Warren Cornwall , Science.  Excerpt: ...the recent fate of snow crabs in much of the Bering Sea. An unprecedented underwater heat wave there in 2018 and ’19 set off a chain reaction that led to the disappearance of an estimated 47 billion crabs, one of the largest marine die-offs ever documented. Suddenly, a $150 million fishery mythologized in the  Deadliest Catch  reality TV show found itself with no catch at all. State regulators for the first time banned Bering Sea snow crab fishing in 2023 and ’24, and the U.S. government declared a federal fishery disaster. The fishery reopened this year.

But what has been a blessing is increasingly a threat, as flooding becomes one of the city’s greatest challenges. Projections that model future flooding in the city show that it will only get worse. By 2080, many areas will face an increased risk of  tidal flooding  because of rising sea levels. At the same time, more neighborhoods will become vulnerable to  extreme rainfall . And wide swaths of the city face increasing peril in the event of  storm surge  from a hurricane. By 2080, nearly 30 percent of the city’s land mass could be  at risk of significant flooding . Some 1.4 million New Yorkers currently live in these areas — 17 percent of the city’s population. New York’s adaptation is a matter of survival. Climate experts have recommended several strategies. The city could increase its ability t...

By By Raymond Zhong , The New York Times.  Excerpt: Fifty miles off the Tuscan coast, in a sparkling blue expanse broken only by rocky, forbidding islets, including the real-life Island of Montecristo, ancient creatures are roosting beneath the waves. They spend their days feasting on an unlikely source of nourishment: methane, a potent greenhouse gas that leaks out of cracks in the seafloor. Lately, researchers have been trying to put these microorganisms to work on an urgent task. If their appetites can be redirected to other sources of their favorite gas — namely, the hundreds of millions of tons of planet-warming methane emitted each year from oil and gas sites, livestock and wetlands — then they might just help slow climate change. First, though, researchers need to better understand these microbes, which have been on this planet for billions of years but remain enigmatic in many ways....  Full article at https://www.nytimes.com/2025/10/06/climate/methane-eating-microbes-...

By Shelby Conn , SFGate.  Excerpt: ...11% of  Siskiyou County  households [are] on the  California FAIR Plan  — a fire-only insurance policy no homeowner wants to turn to. ...the reality for many residents and business owners living in California’s rural, high-fire risk areas, where costly insurance rates are forcing homeowners who own their properties outright to forgo insurance altogether. ...“The FAIR Plan is not intended to compete with or replace insurers in the voluntary market.” Rather, it is meant to provide “basic fire insurance coverage for high-risk properties when traditional insurance companies will not,” she said.  The state’s escalating wildfire risk has driven more and more insurers  out of the market  in California. A study funded by the  National Integrated Drought Information System  estimated that, between 1971 and 2021, the number of acres burned in California rose by 172%.

By Antonio Piemontese , Wired.  Excerpt: Speaking by video  at the UN Climate Summit in New York last week,  China's  president Xi Jinping laid out his country's  climate  ambitions. While the stated goals may not have been aggressive as some environmentalists would like, Xi at least reaffirmed China's green commitment. “Despite some countries going against the trend, the international community should stay on the right track, maintain unwavering confidence, unwavering action, and undiminished efforts,” he said. Any reference to Donald Trump and the United States was surely intended (though not explicit). ...Xi Jinping's speech included a commitment to reach 3,600 gigawatts (GW) of installed wind and solar capacity by 2035, six times the country's 2020 figures. This is already the leading country in terms of installed renewable power, and a giant on the technology front as well, with universities churning out environmental and climate tech research at full ...

By Kaja Šeruga , Eos/AGU.  Excerpt: The towering trees of old forests store massive amounts of carbon in their trunks, branches, and leaves. When these ancient giants are replaced by a younger cohort after logging, wildfire, or other disturbances, much of this carbon stock is lost. ...The resulting study, published in  Nature Ecology and Evolution , measured the regional net aging of forests around the world across all age classes between 2010 and 2020, as well as the impact of these changes on aboveground carbon. ...On average, forests that are at least 200 years old store 77.8 tons of carbon per hectare, compared to 23.8 tons per hectare in the case of forests younger than 20 years old. The implications for carbon sequestration are more nuanced, however. Fast-growing young forests, for instance, can absorb carbon much more quickly than old ones, especially in the tropics, where the difference is 20-fold. But even this rate of sequestration is not enough to replace the old fo...

By Nicolás Rivero  and  Jake Spring , Washington Post.  Excerpt: The Energy Department on Wednesday canceled $7.56 billion in funding for 223 projects aimed at research and deployment of clean energy and other climate-friendly technology mainly in Democratic-led states. The cuts are the latest in President Donald Trump’s efforts to undercut renewable energy and other efforts to reduce the emissions driving climate change. The administration has already sought to claw back funding allotted under President Joe Biden’s signature climate law, the Inflation Reduction Act. That includes  $20 billion from the Greenhouse Gas Reduction Fund , which supported investments in green technology like heat pumps and electric vehicles, and  $7 billion in the Solar for All program  to help low- and middle-income families install rooftop solar. The latest cuts include a  $1.2 billion award for ARCHES H2 , ...aimed at kick-starting the hydrogen industry in California.... ...

By Brad Plumer  and  Lisa Friedman , The New York Times.  Excerpt: The Trump administration on Monday outlined a coordinated plan to revive the mining and burning of coal, the largest contributor to climate change worldwide. Coal use has been declining sharply in the United States since 2005, displaced in many cases by cheaper and cleaner natural gas, wind and solar power. But in a series of steps aimed at improving the economics of coal, the Interior Department  said it would open  13.1 million acres of federal land for coal mining and reduce the royalty rates that companies would need to pay to extract coal. The Energy Department  said it would offer $625 million  to upgrade existing coal plants around the country, which have been closing at a fast clip, in order to extend their life spans. The Environmental Protection Agency said it would repeal dozens of regulations set by the Biden administration to curb carbon dioxide, mercury and other pollutant...

By ScienceAdviser.  Excerpt: Polyethylene terephthalate or PET is one of the most widely used plastics, and therefore, a big contributor to plastic waste. But a team of researchers  has an idea for how to beat the trash—and help tackle climate change at the same time . In a recent paper, they described a simple process that turns PET into bis-aminoamide (BAETA), a compound that chemically binds carbon dioxide (CO 2 ), effectively pulling it from the air. “ Any useful carbon capture material needs to be made in the millions of tons per year from cheap and abundant sources ,” co-author Ji-Woong Lee told  Chemical & Engineering News . “Plastic waste is a cheap and abundant source.” Lee and colleagues detailed how, simply by mixing PET with 1,2-ethylenediamine (EN) at 60°C for 24 hours or room temperature for 2 weeks, they could turn the plastic into CO 2  -absorbing BAETA. ...“ The beauty of this method is that we solve a problem without creating a new one ,” lead a...
