After more than eight years in lower courts, Boulder’s case against two oil giants will kick off the Supreme Court’s new term.

In Wyoming’s Beartooth Mountains, scientists are studying ice that has survived for thousands of years — and what could help some patches persist as the climate warms.

Scientists say a warming climate is making extreme weather events like flash floods, heat waves, and hurricanes more intense. But how certain are they that climate change contributed to a specific disaster?

2 More bear attacks in southwestern Colorado add to a record season of conflicts with humans. Read the article from the Colorado Sun and then listen to the interview with KUNC host Marty Lenz.

Researchers have grown increasingly confident in global warming’s role in post-2000 ‘megadrought’ and its impact on the Colorado River.

As the climate warms, some mountain trees are moving higher up, while others are spreading downhill. Scientists say something inside the trees may explain why. And that split could reshape watersheds and wildfire risk.

A new study found that human-caused warming increased the chances of snow conditions this severe.

Much of the local economy from Aspen to Parachute is focused on the outdoors. But this summer's drought and the record-low snow year raise questions about how businesses can diversify in a changing climate.

This past winter was a tough one for Colorado's ski resorts, with warm temperatures and little snow.
