"Positive 'greening' of our daily activities may soothe our consciousness, but a sole focus on the individual consumer level runs the risk of displacing or subsuming attention paid to larger-scale organizational carbon practices in the private as well as public sectors."

Greenland is home to more than 3,000 ice marginal lakes: pools of meltwater trapped by glaciers that have dammed river valleys or depressions. Glacial lake outburst floods (GLOFs) happen when those dams break and release catastrophic floods of meltwater.
Machine learning helps scientists detect glacial lake outburst floods in Greenland
New method developed at CIRES helps glaciologists understand how and when these climate hazards occur

What would it be like to have dozens of instruments in your home next to dustpans and in your kitchen to measure what's in the air? Last summer, CU Boulder Engineering Professor Marina Vance took scientific field research to a new level.

CUriosity: Why hasn’t it snowed much this year, and what does that mean for Colorado?
This year, the normal blizzards haven't come to most of Colorado, but atmospheric scientist Jennifer Kay says there's still time for the season to turn around.

The 2022 Hunga eruption increased global stratospheric water vapor by about 10%, much of which remains in the atmosphere through 2025. CIRES scientists Yunqian Zhu and Lizzy Asher narrate this video and contributed to the @wcrpclimate.bsky.social report released today.
