In INSTAAR's Stable Isotope Lab lie rows of metal flasks holding clues to the cause of an alarming rise in a powerful greenhouse gas. They contain samples of air from around the world that Sylvia Michel鈥榮 team of methane detectives analyse to reveal whether the gas came from burning fossil fuels and wood, or from wetlands and cow guts.

With a changing climate, fires in far northern forests that smolder throughout winter and erupt again in spring could become more common.

Heat and shifting weather patterns have intensified wildfires and reduced water supplies across the Southwest, the Pacific Coast, and North Dakota. Keith Musselman quoted.

"Zombie fires" may sound like something straight out of science fiction, but they're a real phenomenon that is likely to become more common in the area ringing the Arctic, and possibly the Arctic itself, as climate change continues, a new study finds. Merritt Turetsky comments on the study and explains its context.

Geologist (and INSTAAR) Robert S. Anderson and astrophysicist Fran Bagenal recognized for 鈥榙istinguished and continuing achievements in original research鈥�.

Report on a management plan for solid waste in Sagarmatha (Mt. Everest) National Park, Nepal, from a paper led by Alton Byers published in Mountain Research Development.

In celebration of Earth Day鈥檚 51st anniversary, CU Boulder Today explores 10 research-related discoveries led by CU Boulder that have the potential to positively change the way we live and soften humanity鈥檚 imprint on our precious planet.

The snowy landscape of the Arctic was greener more than 100,000 years ago and could get there again as the climate warms and plants migrate further north, new research suggests. Plant DNA taken from soil 10 meters below a lake near Clyde River shows dwarf birch shrubs used to grow up to the northernmost point of Baffin Island, according to research led by Sarah Crump, published in the journal Proceedings of the National Academy of Sciences. The samples, more than 100,000 years old, were found in soil and were more intact than samples from permafrost, suggesting they may have remained unfrozen.

Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today. Carbon dioxide levels are now higher than at anytime in the past 3.6 million years. The article mentions the analyses done in INSTAAR's Stable Isotope Lab.

More snow is melting during winter across the West, a concerning trend that could impact everything from ski conditions to fire danger and agriculture, according to a new CU Boulder analysis of 40 years of data, led by Keith Musselman.
