A WMO international committee of experts working under the auspices of the Weather and Climate Extremes Archive conducted a detailed analysis and verification of the distance and duration. The evaluation committee recognized...

A triple whammy of accelerating sea level rise, ocean warming and acidification is imperilling Pacific Islands, which face growing threats to their socioeconomic viability and indeed their very existence because of climate...

Extreme heat hit hundreds of millions of people throughout July, with a domino effect felt right across society. July was one of the hottest - if not the hottest - month on...

Sand and dust storms (SDS) have increased dramatically in intensity and frequency in recent years, especially in some regions, highlighting how the phenomenon damages crops and livestock, worsens desertification, and causes health...

The Copernicus satellite missions currently in orbit provide invaluable data that feed a vibrant ecosystem of Earth Observation products and services across diverse application areas. Copernicus is served by a set of...

Climate change impacts are becoming increasingly severe, posing unprecedented challenges. Dramatic climate action is needed to limit global warming, requiring unprecedented societal transformations to sustain the future of life on Earth, a...

From mountain tops to ocean depths, the summer of extremes continues. Heatwaves are baking large parts of the northern hemisphere, fuelling unprecedented wildfires and disrupting marine ecosystems. Floods have transformed desert landscapes....
