Switzerland's glaciers lost more than 5% of their ice volume in 2026. Although melt rates did not quite reach the record levels of 2022, glacier thickness decreased by an average of 2.5 to 4 meters (8 to 13 feet) this year, and some glacier tongues lost up to 10 meters (33 feet) of ice. The research is published in…
Ice cores recovered from an ice cap in northwestern Tibet appear to preserve fragments of ancient ice from the last ice age, extending Earth's glacial record by more than 100,000 years and making them the oldest ice cores ever recovered from the region, according to a new study.
A few days of rain do not change low groundwater levels after a long drought. To better determine how groundwater systems recover after a drought and which groundwater reserves are most vulnerable, hydrologist Sandra Hauswirth developed a method to classify groundwater systems based on their ability to recover from…
Irrigation canals form a sort of circulatory system for global agriculture. Across the world, millions of kilometers of human-made canals carry water from lakes, rivers and reservoirs downhill to farmland. Canals are vitally important to human food production, yet many agricultural areas lack the means to monitor the…
For communities along the Gulf Coast, hurricane season presents a recurring challenge: knowing when, where and how to evacuate before a major storm hits. To tackle this, researchers at Texas A&M University have spent more than a decade helping local, state and federal agencies develop clear, data-driven evacuation…
Sea-level rise is one of the most visible signs of climate change, one that is threatening low-lying coastal communities around the world. Today, about 1 billion people live in coastal areas; about 100 million live within 1 meter (3.3 feet) of sea level, highly exposed to coastal flooding.
As a powerful nor'easter hit the U.S. Atlantic coast in late September 2026, the ocean poured into coastal neighborhoods from North Carolina to New York. Water from the storm surge and heavy rain filled streets and surrounded homes as near-hurricane-force winds knocked out power. It may have even uncovered a shipwreck…
Climate change is increasingly reshaping the polar oceans, with Arctic waters warming rapidly, sea ice shrinking and wildlife losing habitat at both ends of the planet, an annual report said Wednesday.
Many cities around the world are sinking because too much water is extracted from the groundwater reservoirs beneath them. This sinking makes these coastal cities more exposed to rising seas as the climate warms. But as our new research shows, this process can work in reverse: When groundwater is replenished, cities…
Over a century ago, Australian geologist Sir Douglas Mawson led a sledding expedition over hundreds of kilometers of ice into a remote part of East Antarctica. The party turned back after the tragic death of a party member. Fellow Australian Cecil Madigan led another group across sea ice into the region before also…
