Depicted is the UC Merced campus in the foreground, with smoke from a distant wildfire seen behind it on a blue sky.
Key points: • Researchers found that heat waves are a critical enabler and driver of wildfire-burned areas across the western U.S. • The findings suggest that heat waves contribute not only to increased flammability, but to longer burn periods and increased lightning...
As climate warms, the snowline, or rain/snow transition elevation, moves to higher elevations, placing some historically snow-dominated sites in the rain zone. Photo by Roger Bales at Crane Flat in Yosemite National Park
A new study co-authored by UC Merced researchers assesses the effect of a warming climate in pushing the elevation of snow to rain higher during a storm, increasing runoff and the risk of flooding...

Rocks, from ponderous boulders to tiny grains of sand, are subject to the whims of moisture, weather and time as they tumble from surrounding slopes into rivers, pools and lakes. UC Merced...
The ¿field curious? group in Yosemite.
When Carlos Martinez was growing up in Southern California, his experience outdoors largely consisted of the irrigated lawns and tidy trees of his local park. Camping and hiking were not in his...

A grant from the National Science Foundation (NSF) will fund a project led by a UC Merced researcher looking into predicting behavior of wildfires. Jeanette Cobian-Iñiguez is leading a team...
A male waterbuck antelope stands knee-deep in receding floodwaters three months after Cyclone Idai made landfall. Three months before this photo being taken, a waterbuck standing in this spot would be totally submerged by Cyclone Idai induced flooding.
How different species of animals respond to extreme weather events — which are increasing because of climate change — appears to be related to body size and habitat preference, a new...
