8 in 10 North American lizards could be at risk due to deforestation (CU Boulder Today)

In a study published March 5 in the journal Nature Climate Change, scientists from CU Boulder and Tel Aviv University in Israel revealed that deforestation combined with climate change could negatively impact 84% of North America’s lizards by the end of the century. Nearly one in five could face population decline. Keith Musselman is one of the three authors.

Research & Innovation Office announces 2024 Faculty Fellows class (RIO)

Dec. 19, 2023

Keith Musselman (INSTAAR & Geography) is one 16 CU Boulder faculty members selected by the Research and Innovation Office as their 2024 RIO Faculty Fellows cohort. The program supports faculty in achieving their research/innovation goals and promotes collaboration, all through tailored training, experiential learning and leadership development opportunities. Musselman and his cohort will kick off 2024 with an intensive three-day retreat in January, followed by several more focused retreats and a variety of informal networking activities.

As rising temperatures affect Alaskan rivers, effects ripple through Indigenous communities (CU Boulder Today)

April 11, 2023

Streamflow is increasing in Alaskan rivers during both spring and fall seasons, primarily due to increasing air temperatures over the past 60 years, creating dangers and difficulties for local communities. New CU Boulder-led research quantifies consequences already observed and experienced for generations by local Indigenous communities who rely on these rivers for their livelihoods.

Why rain on snow in the California mountains worries scientists (The Conversation)

March 14, 2023

Another round of powerful atmospheric rivers is hitting California, following storms in January and February 2023 that dumped record amounts of snow. This time, the storms are warmer, and are triggering flood warnings as they bring rain higher into the mountains on top of the snowpack. Keith Musselman explains the complex risks rain on snow creates and how they might change in a warming climate.

Water resources to become less predictable with climate change (NCAR & UCAR News)

July 18, 2022

Water resources will fluctuate increasingly and become more difficult to predict in snow-dominated regions across the Northern Hemisphere by later this century, according to a comprehensive new climate change study. Even regions that keep receiving the same amount of precipitation will experience more variable and unpredictable streamflow as snowpack recedes.
