Clear-cutting can make catastrophic floods 18 times more frequent with effects lasting more than 40 years, according to a new UBC study.... Read more

At least three people were killed and more than 1,000 evacuated Thursday after South Korea was hit by torrential rains, officials said, with one region pummeled by the most rainfall per hour since full records began.... Read more

Heavy rains have been linked to 54 deaths in the last 24 hours in Pakistan, taking the toll to about 180 since the arrival of the monsoon in late June, the government's disaster agency said on Thursday.... Read more

Heat waves are becoming more frequent around the world. And while rising temperatures caused by greenhouse gas emissions are part of the problem, the declining levels of aerosols—the small particles that make up smog and air pollution—may be driving the rise even more, particularly in populated areas....

Satellites circling Earth have many different functions, including navigation, communications and Earth observation. About 8%–10% of all active satellites are military or "dual use" serving intelligence or reconnaissance functions as spy satellites.... Read more

June's heat wave has caused French Alps snow and glaciers to melt faster, causing water shortages at mountain shelters just before the summer tourist hiking season gets into full swing.... Read more

With four areas of the U.K. now facing drought conditions, new research from the University of Surrey shows that helping households use less water means first understanding their everyday habits—and getting the public onboard attempts to change those habits.... Read more

Monitoring changes in water temperature and pressure at the seafloor can improve understanding of ocean circulation, climate, and natural hazards such as tsunamis. In recent years, scientists have begun gathering submarine measurements via an existing infrastructure network that spans millions of kilometers around the planet: the undersea fiber-optic telecommunications cables...

Antarctica's patterns of stark seasonal changes, with months of darkness followed by a summer of 24-hour daylight, prompted us to explore how a Māori lunar and environmental calendar (Maramataka) might apply to the continent and help us recognize changes as the climate continues to warm....

In an analysis of the best available Earth systems models, Northeastern researchers found that by the turn of the next century, 850 million people will feel the effects of declining runoff from the world's major rivers.... Read more

Reviving floodplain wetlands slashes carbon emissions by 39% and restores critical ecosystem functions in one year—without the methane spike typically seen in restored peatlands, a new study has found.... Read more

As nations worldwide race to meet the 2050 carbon neutrality target, Japan has emerged as a key player in implementing "green transformation" (GX)—a comprehensive shift from fossil fuel dependency to renewable energy as a primary power source. Unlike other countries, the Japanese government views this shift not only as an... Read more

The landslide that occurred in Blatten in the canton of Valais at the end of May 2025 and the one in the village of Brienz in Graubünden in June 2023 remind us of the potential for landslide hazards in the Alps. Debris flows are one such hazard. These flows of... Read more

Glaciers hold layers of history preserved in ice, offering unique insights into Earth's past that can also help us interpret the future. Trapped amidst the frozen water are microscopic deposits of dust, pollen, and even pollutants that scientists can use to examine environmental changes through time.... Read more

New research led by the University of Victoria (UVic) has illuminated a significant and previously unrecognized source of seismic hazard for the Yukon Territory of northwestern Canada.... Read more
