New observations help explain why the southern hemisphere is warming less quickly than the northern hemisphere.

"Proxies" in geologic record show rainfall was more intense, but less regular during the Paleogene.

The rise in wildfires globally brings into sharp focus how such disasters increasingly threaten our health and security. One question many people ask is how poor air quality could be harming their health.

Researchers from the IIASA Biodiversity and Natural Resources Program are involved in the recently launched EU-funded Trees4Adapt project.

Shortly after the Palisades and Eaton fires broke out in Los Angeles Jan. 7, 2025, engineers from the UCLA Samueli School of Engineering mobilized across burn zones to support recovery efforts and implement immediate mitigation strategies, including field reconnaissance, soil and water testing and infrastructure mapping.

A record of repeated retreat of the West Antarctic Ice Sheet during the past warm climates has been identified by International Ocean Discovery Program (IODP) Expedition 379 Scientists.

Higher temperatures may make monarch butterflies more vulnerable to parasites, according to new research from the University of Georgia.

In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates are doing surprising well, highlighted by flourishing fish populations.

A new study co-led by the University of Oxford has found that global aviation emissions could be reduced by 50-75% through combining three strategies to boost efficiency: flying only the most fuel-efficient aircraft, switching to all-economy layouts, and increasing passenger loads. Crucially, the study shows that around a 11% reduction in global aviation emissions is achievable immediately, by using the most efficient aircraft that airlines already have more strategically on routes they already fly.
