‘Snow-eater’ heat waves are melting western U.S snowpack twice as fast

Some trees are making air quality in cities worse: willows and poplars, widely planted in cities, release high levels of isoprene, a VOC that reacts with nitrogen oxides to form ozone

Fire managers rely on pre-1849 conditions to guide wildfire decisions

Hawaii’s dolphin tourism boom may be taking a toll on spinner dolphins, study finds

A study found single-use paper cups release millions of micro- and nanoplastic particles when exposed to hot water, with biodegradable PLA-lined cups releasing about 12 times more plastic by mass than conventional polyethylene-lined cups.

Harvesting rainwater from rooftops could help cities stay cool and cut the number of heatwave days

Low-smoke fuels for residential heating linked to an increase in ultrafine particle emissions

A global study using more than two decades of observations from 156 sites found permafrost degradation accelerated between 2000 and 2024, with the seasonally thawed active layer thickening across much of the Arctic…

The World Is Running Out of River Sand, And That's a Massive Issue

No place on Earth is resilient to all global catastrophic risks, according to a review on nuclear winter, volcanic eruptions, pandemics, and infrastructure collapse

Magnetically driven MXene–nickel microrobots bound and retrieved microplastics from laboratory water and soil samples

Rainfall across the US is increasingly coming from farther away

A study found off-equatorial Pacific warming helped prevent La Niña from developing in 2024 by generating westerly winds that blocked cold ocean signals from spreading eastward, helping explain why most climate models incorrectly forecast stronger cooling.

Study find that in Portland, the areas most vulnerable to multiple climate hazards are historically underinvested neighborhoods marked by lower median incomes, lower education levels and higher racial diversity.

Review suggests insects shifting uphill to escape climate warming may face physiological limits from lower oxygen and air pressure, with flying insects and active juveniles particularly vulnerable, potentially constraining their ability to track suitable temperatures.

Species missing from restored forests and wetlands | Biodiversity recovery is slow following clear-cut harvest of boreal forests

In the U.S coastal wetlands—among the country's most valuable ecosystems, protecting infrastructure and providing homes for wildlife—are losing ground: 84% are gradually inundating…

Ecological stoichiometry and nutrient reduction strategies for intensive yet sustainable hybrid pond systems – concepts for regenerative aquaculture.

Industrial-scale illegal and unreported fishing accounts for an estimated 8–15% of global marine wild catch and supports an illicit seafood trade worth US$6.2–12.2 billion annually, with about two-thirds of its value originating in West Africa…

Marine heatwaves may threaten human health by intensifying extreme weather, promoting harmful algal blooms, disrupting seafood supplies and livelihoods, and contributing to anxiety and grief in coastal communities…

Climate modeling suggests that under a high-emissions scenario, hot days could gain more than four additional hours of extreme heat by the end of the 21st century, with hourly measurements revealing heat exposure missed by traditional daily temperature indicators.

Study of 220,000 deaths across Chicago found neighborhoods losing tree canopy over 11 years experienced higher mortality, while annual increases in urban tree cover were associated with fewer deaths…

An analysis of nearly 3,500 wildfires across western North America found faster-spreading fires caused more severe tree mortality and left burned areas farther from surviving seed trees, reducing the ability of conifer forests to naturally recover.

Climate modeling projects that Europe’s annual burned area could increase by about 39% by 2070–2100 under a low-emissions scenario and 192% under a high-emissions scenario, as hotter, drier and windier conditions increase wildfire activity.

An assessment of food systems across 197 countries finds that fewer than one-third are on track to meet 2030 targets for 22 of 30 indicators, while no country is projected to meet the target for food-system greenhouse gas emissions at its current pace.

Many US public parks sit surprisingly close to hazardous waste sites and facilities that release toxic chemicals

Long-term observations across Ireland show rising urban ozone, while the highest ozone concentrations and exceedances occur at remote coastal sites

An international update of 12 climate indicators estimates that human-caused warming reached 1.52°C above pre-industrial levels in 2025, with greenhouse gas emissions and Earth’s energy imbalance remaining at or near record highs.

Study of more than 25,000 trees and palms in regenerating Amazon forests found just 15–25 pioneer species dominate early forest recovery and carbon storage, rapidly colonizing degraded land and creating conditions that allow mature-forest species to return.
