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 .

By Paul Voosen , Science.  Excerpt: Global greenhouse emissions will soon flatten or decline—a historic moment driven by China’s surge in renewable energy. In July, a team of scientists assembled...to study an anomalous wobble in a data curve. ...it was a surprising decline in a quantity that has grown relentlessly throughout the Industrial Age: the amount of planet-warming greenhouse gases dumped by humanity into the atmosphere each year. The researchers were members of Climate TRACE, a collaboration of academics, environmental think tanks, and companies that tracks how much coal, oil, and natural gas the world is burning—and where—using a mix of energy statistics, satellite observations, and artificial intelligence (AI). As the group began to push out monthly estimates for January, February, and March, it was unmistakable that levels were lower than at the same time last year. ...overall emissions have crept up by some 1% each year. Although Europe and the United States reached p...

By Cara Buckley , The New York Times.  Excerpt: Iowa City eliminated bus fares in August 2023 with a goal of lowering emissions from cars and encouraging people to take public transit. The two-year pilot program proved so popular that the City Council voted this summer to extend it another year, paying for it with a 1 percent increase in utility taxes and by doubling most public parking rates to $2 from $1. Ridership has surpassed prepandemic levels by 18 percent. Bus drivers say they’re navigating less congested streets. People drove 1.8 million fewer miles on city streets, according to government calculations, and emissions dropped by 24,000 metric tons of carbon dioxide a year. That’s the equivalent of taking 5,200 vehicles off the roads....  Full article at https://www.nytimes.com/2025/11/18/climate/iowa-city-free-buses.html . 

By Paul Voosen , Science.  Excerpt: For all their usefulness in forecasting global warming, climate models tend to paint the future in the broad strokes of an Impressionist artist. ...Now, a new high-resolution modeling project called MESACLIP, run at great computational expense over the past 5 years, is putting Earth’s future into sharper focus by simulating the churning of the atmosphere and ocean at a level of detail similar to the scale of weather forecasts. The project reveals heightened risks for regions like the Gulf Coast and coastal California, where extreme rainfall could occur far more often than traditionally projected. The trends, published today in  Nature Geoscience ,  show the benefit of high-resolution models , which better capture shifts in wind patterns that lead to the downpours....  Full article at https://www.science.org/content/article/high-resolution-climate-model-forecasts-wet-turbulent-future .

By Anupreeta Das , T he New York Times. Excerpt: India is getting hotter, faster. The grim present presages a grimmer future for the world’s most populous country, which is experiencing more frequent and severe heat waves. But India — with 1.4 billion people, many of whom are impoverished and particularly vulnerable to climate change — has yet to grasp the magnitude of the problem and may be underequipped to deal with it, public health experts and scientists say. ...Numerous studies suggest that India undercounts such deaths. In part, that is because most government doctors follow a narrow definition of what classifies as a heat-related death, sticking to easily identifiable causes like heat stroke, experts say....  Full article at https://www.nytimes.com/2025/11/16/world/asia/india-heat-wave-deaths.html .  See also Women Toiling in India’s Insufferable Heat Face Mounting Toll on Health . 

By Robert Sanders , UC Berkeley News.  Excerpt: Sea urchins are a key but often destructive part of the kelp forest ecosystem along the Pacific Coast, and in boom years can often turn these forests into barrens devoid of marine life. But it remains a mystery what causes urchin boom and bust cycles and how sea urchins are affected by increasingly common marine heat waves. A new study by marine biologists at the University of California, Berkeley, now suggests that sea urchin populations along the Pacific Coast are more susceptible to heat waves than once thought, because the animals ramp down reproduction at temperatures substantially below levels that kill them. ...The study,  published last week  in the journal  Communications Biology , a  Nature  journal, was conducted in cooperation with the Hakai Institute in British Columbia, Canada, and UC Davis’s Bodega Marine Laboratory in California....  Full article at https://news.berkeley.edu/2025/11/14/ev...

By Hannah Richter , Eos/AGU.  Excerpt: More than 75 million people work in the garment industry, many of them in the world’s hottest countries. As climate change warms the air and oceans, so too does it seep into the stuffy chambers of garment factories, where conditions are highly uncomfortable if not downright unsafe. In  research recently published in  The Lancet , scientists tested different interventions for protecting workers from rising temperatures in Bangladesh, a nation where 80% of its export revenue comes from the garment industry. The 4 million Bangladeshi people, mostly women, who sew ready-made garments often work 12-hour shifts 6 days a week in humid and poorly ventilated buildings. Prolonged heat stress can put strain on their cardiovascular systems and increase their risk of heat stroke, especially because many workers have existing kidney and cardiovascular issues....  Full article at https://eos.org/articles/garment-factories-are-heating-up-heres-...

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  Erin Douglas ,  Inside Climate News .  Excerpt: This mosquito species is native to tropical and subtropical climates, but as climate change pushes up temperatures and warps precipitation patterns, the  Aedes aegypti   —  which can spread Zika, dengue, chikungunya and other potentially deadly viruses — is on the move. It’s popping up all over the Mountain West, where conditions have historically been far too harsh for it to survive. In the last decade, towns in  New Mexico  and  Utah  have begun catching  Aedes aegypti  in their traps year after year, and just this summer, one was found for the  first time in Idaho . ...as climate change allows the  Aedes aegypti  to move northward, survive at higher elevations and stay active for longer into the fall, dengue virus is fast emerging as one of the most dangerous of the world’s diseases transmitted by mosquitoes and  ticks , researchers say.......

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. Having  saturated its own market  with solar panels, wind turbines and batteries, Chinese companies are now exporting their wares to energy-hungr...

By Max Bearak , The New York Times.  Excerpt: ...Fatih Birol... has led out of obscurity over the past decade, the International Energy Agency [IEA]. ...Mr. Birol likes to joke that he is “the world’s most boring man.” He certainly exudes a kind of bureaucratic plainness. 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. Even a small increase in wind speed can cause substantial damage, said Friederike Otto, one of the group’s founders and a climatologist at Imperia...

By Paul Voosen , Science.  Excerpt: It’s a hallmark prediction of climate change: As the world warms, trees will migrate not just toward the poles, but also up the slopes of mountains, eating away at fragile alpine ecosystems. Although advancing tree lines have been tracked at individual mountains, a new large-scale study  has found something surprising : Over a span of 4 decades, the largest upward movement of these forests has come not near the poles, as one might expect, but instead in the tropics, where monitoring has been far more limited....  Full article at https://www.science.org/content/article/forests-are-migrating-mountain-peaks .

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 ...
