Just 3% of the world's glaciers account for over half of glacier ice loss

Glaciers ending in lakes, oceans or ice shelves make up 3.2% of the world's glaciers, but lost 134 billion metric tons (148 billion tons) of ice each year between 2000 and 2019, accounting for more than half of all glacier ice loss, a new study shows.

East Asia's summer rain belt has shifted north over decades, reshaping rain and heat risks

A joint research team from KAIST and the APEC Climate Center has found that the East Asian summer front has migrated north over the past half century, with the shift exceeding 200 km (124 miles) in late summer. This raises the risk that the Korean Peninsula will experience heavy rain and heat stress at the same time. The findings suggest that summer disaster planning should address flood prevention and heat-illness management together, through late September.

El Niño then and now

El Niño is part of a natural climate pattern that occurs roughly every two to seven years, bringing warmer-than-normal water to parts of the equatorial Pacific. The most recent very strong El Niño events, in 1997–98 and 2015–16, upended weather patterns. Impacts spanned the planet, from fires in Indonesia and the Amazon to crop failures due to drought in southern Africa to heavy rain and coastal flooding in Southern California. The current El Niño rivals these past heavyweights.

Sinking Antarctic ice reveals a hidden lake's massive water loss

The Kronshtadskiy subglacial lake near East Antarctica's Amery Ice Shelf was hidden beneath Antarctica's ice, but its drainage left a mark visible from space as a broad depression that deepened by more than 6 meters (20 feet) at its center.

US drinking water could contain double the reported PFAS levels, model estimates

Common ways of reporting perfluoroalkyl and polyfluoroalkyl substances (PFAS)—the man-made, so-called forever chemicals that pose environmental and health threats—could underestimate the concentration of PFAS in U.S. drinking water by as much as half, according to a study being published Oct. 23 in Cell Reports Sustainability.

Summer 2026 heat toll exceeded 50,000 deaths in European cities, analysis estimates

More than 50,000 heat-related deaths are estimated to have occurred in urban areas across Europe during summer 2026, with around two-thirds attributed to human-induced climate change, according to new research led by the London School of Hygiene & Tropical Medicine (LSHTM) and Imperial College London.

Strategic new protections could link 13 Pacific deep-sea reserves into connected network

Protected areas have been set up to shield deep-sea life from the impacts of seabed mining in the Pacific Ocean. However, new research led by scientists at Plymouth Marine Laboratory (PML) and published in Nature Ecology & Evolution highlights an opportunity to make these protections even more effective.

Massive carbon stocks in grasslands are ignored by climate finance

Open ecosystems—nonforested landscapes such as grasslands, shrublands and savannas—can store vast amounts of carbon while supporting water supply, biodiversity and other ecosystem services. Yet the potential of open ecosystems to serve as natural climate solutions remains ignored by policies that privilege forests. So reports a team of researchers in a policy brief published today in PLANTS, PEOPLE, PLANET.

Scientists find key to predicting some El Niño events 12 months ahead

Scientists have identified the conditions that make it possible to predict some El Niño and La Niña events up to a year in advance, potentially giving communities and decision-makers significantly more time to prepare for weather extremes.

As flood risk rises, some communities question the idea of resilience

Climate change is increasing flood risk across the U.K. As floods become more frequent and intense, communities are increasingly encouraged to become resilient and "live with water." Yet in some flood-prone areas, residents are rejecting these calls, concerned that resilience is less about helping communities and more about transferring responsibility from institutions to citizens.

Study maps the human side of flood risk

When heavy rain hits a city, knowing where water will accumulate is only part of the picture. Who lives in the affected buildings? How might flooding disrupt their lives? And where could additional support make the greatest difference?

Child-led citizen science helps Ecuadorian community tackle beach pollution and shape environmental decisions

Pollution from human-generated waste in marine ecosystems has reached critical levels, with cigarette butts (CBs) among the most persistent and harmful pollutants. Globally, an estimated 4.5 trillion cigarette butts are discarded annually, making them the most common type of litter on beaches over the past three decades.
