Colorado's state climatologist said long-range forecasts are also not signaling a 'Miracle March.'

Researchers at the University of Nevada, Reno, have received a $9 million grant from the U.S. Department of Energy to study an unlikely candidate for future fuels: cactus pear.

The team, led by a Boise State University civil engineering researcher, looked at half a million wildfire starts, and hundreds of attributes about them. Beyond the obvious weather variables like wind speed, temperature and humidity, they also considered human factors like density of development.

A new report finds 2025 brought widespread drought, massive wildfires and destructive windstorms across several Mountain West states — and underscores how closely connected those disasters have become.
