In 2025, along parts of Kamchatka's coast in Russia, a magnitude 8.8 earthquake caused a tsunami to surge nearly 20 meters (65 feet) above sea level. Yet across the Pacific, its waves were much smaller than those produced by the region's great 9.0 earthquake in 1952. How could the tsunami climb so high near the source…
Marine heatwaves may be only the most intense part of much longer warming events, with elevated temperatures sometimes lingering for months. Researchers found that conventional measurements underestimate total heat exposure by more than 150% on average, potentially overlooking a major source of stress on marine…
Heat waves and wildfires combined with human-caused emissions this year to expose one-third of the world's population to extremely high levels of ozone pollution, a European Union report said Wednesday.
Fueled by record-breaking drought and unusually high temperatures, Canada's 2023 wildfire season was the worst in the country's history, with more than 15 million hectares (37 million acres) charred. Smoke blanketed the eastern seaboard, with health alerts keeping people indoors as skies turned an eerie orange.
We have long known every tonne of carbon dioxide matters to the climate. But governments keep approving new fossil fuel projects—even as climate change worsens.
From the air, Wainwright, Alaska, looks like a perfectly stable band of homes and roads between the Chukchi Sea and a vast, flat tundra. But just below the surface, the frozen ground on which this town was built contains large bodies of ice. Along the eroding coastal bluffs, that hidden ice is becoming exposed and…
Plastic pollution is a growing threat to marine environments, with discarded waste reaching from coastlines to the deepest parts of the ocean. Now, a six-year study has revealed how quickly debris can accumulate on a beach in Ecuador, with one monitoring site collecting about 570 grams (1.25 pounds) of debris every…
A false sense of security can be dangerous. The "Safe Development Paradox" is a phenomenon in which flood-control infrastructure makes people feel safe, so communities subconsciously start building closer and closer to historically vulnerable lowlands.
Climate patterns in the tropics help determine how much snow falls from year to year in Antarctica, one of the coldest, windiest and driest places on Earth. New research from the University of Utah shows that tropical conditions and the oceans also influence the continent's massive ice sheets.
Hurricane Polo made landfall on Mexico's Baja California peninsula on Tuesday, cutting power and causing flooding as the sea breached coastal defenses.
The South Asian summer monsoon has long been known to shape the Mediterranean climate thousands of kilometers away as part of a phenomenon known as the "monsoon–desert" mechanism. Through this mechanism, intense monsoon convection during the summer releases large amounts of heat into the atmosphere, triggering…
