Yale's Climate Opinion Maps now include questions asking Americans about specific extreme weather events like wildfires and floods and how they relate to climate change. More than other Mountain West states, Colorado residents link climate change to these severe weather events.

A federal judge recently ordered the U.S. Department of Agriculture (USDA) to scale back its use of pesticides in all western states. Environmental groups say the ruling is a big step toward protecting rangeland wildlife.

An analysis of federal data shows a 41% rise nationally in emergency room visits due to extreme heat incidents last year. It’s hitting vulnerable Americans the hardest.

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 study led by the University of Michigan shows that large livestock farms are polluting the air across the U.S., including parts of the Mountain West. Researchers say these impacts are felt hardest by nearby communities, where people of color often live.

A new report from the Bureau of Reclamation shows water levels in Lake Powell and Lake Mead remain low. It predicts those conditions could continue or worsen over the next two years. CU Boulder's Chris Winter says this should spur the seven states in the basin to agree on new operating guidelines for the future.

A University of Utah study used data from wildfires in the Sierra Nevada Mountains in Northern California to look at how private forests for industrial timber harvest were impacted by severe fire weather, brought about by climate change.

New data from the Bureau of Reclamation puts the river and its reservoirs in formal shortage conditions. Policymakers are stuck on ways to fix that in the years to come.

Historically dry fuels and long stretches of fire weather have led to the conditions driving one of Colorado's biggest wildfires. Some experts are saying that climate change, which creates these conditions, could make these kinds of fire the new normal.

Wildfires throughout the Mountain West have caused significant air quality problems this summer, even for communities miles away from the fires. CU Boulder's Joost de Gouw says that's because of how particles in the smoke interact with the atmosphere.
