For hundreds of years, Hispanic communities across the Southwest have relied on these networks of hand-dug irrigation ditches to water their crops and feed their families. Now, these ancient traditions are under pressure from a changing climate.

Climate change could be taking a toll on the smallest creatures in the Mountain West. A new study finds insect populations in one mountain valley have plunged by more than 70% in recent decades. Scientists say this trend could shake the food chain in alpine areas across the region.

A new scientific analysis shows that fall temperatures are rising across the country because of climate change, especially in the Mountain West. More than simply a delay in sweater weather, experts say this trend has more serious impacts.

A new study finds that human emissions are the main culprit behind the decades-long drought that ebbs and flows across the Western U.S. Scientists warn the drier pattern could become the new normal, with major implications for water supplies.

A new report finds multi-day streaks of extreme heat are becoming stronger and lasting longer across the U.S., especially in Mountain West states. Experts warn that heatwaves are not only a health concern, but can strain energy resources.

A new study shows climate change is causing the Earth’s supply of fresh water to quickly disappear. One of the world’s fastest-drying regions is the American Southwest, where future food supplies could be threatened.

A new analysis shows that climate change is causing the number of extremely hot summer days to rise in most major U.S. cities. Some of the biggest increases are in the Mountain West.

Nationwide, tens of thousands of Indigenous households use firewood to help heat their homes. That’s why the Washoe Tribe of Nevada and California is making sure their elders have the chopped wood they need.

A new scientific analysis shows spring is getting warmer across the U.S. because of climate change. Some of the fastest-warming cities are in the Mountain West, threatening to shrink water supplies and increase wildfire risk.
