climate change

National monuments across the West do more than preserve iconic landscapes — they also help protect the rivers millions of people rely on for drinking water. But a new analysis warns those protections could weaken under the Trump administration’s push to redraw the boundaries of several monuments.

New research shows that mountain regions around the world are warming faster than the lowlands below them. Scientists say that could have big consequences for the Mountain West, where communities rely on snow and ice for their water supply.

New research shows that many rural roads in the Mountain West may be more vulnerable to flooding than people realize. That’s because the culverts and stream crossings underneath them aren’t built to handle today’s storms.

A new study in the Rocky Mountains has found a steep drop in the number of young American pikas — small, high-altitude mammals known for their distinctive squeaks and rock-pile homes. Researchers say the 50% decline could be an early sign of deeper ecological shifts as the climate warms.

A new study in the journal Science suggests rivers in the arid American West may be doing something unexpected: absorbing carbon dioxide from the atmosphere. The finding could reshape how scientists model climate change.

A new study finds that what Americans eat — particularly beef — plays a major role in carbon emissions in cities. And cities in the Mountain West rank among those most heavily impacted.

Late-spring frosts aren’t just tough on gardens — they’re creating new challenges for black bears in the Mountain West.

A proposal to build one of the largest solar projects in the U.S. has been abruptly halted by the Trump administration — a move critics say undermines the nation’s renewable energy transition.

A new study shows Nevada’s groundwater — and the ecosystems that rely on it — is under growing strain. Researchers have mapped out solutions that could help and serve as a guide for other Mountain West states.

AI data centers use large amounts of water for cooling. And many are being built in the drought-stricken Mountain West, sparking concerns over water supplies.
