Aurora alert! The aurora could be visible tonight. Will you have a chance to see it? Check the forecast! CIRES and NOAA researchers work on the aurora forecast product on the NOAA Space Weather Prediction Center webpage: www.swpc.noaa.gov #aurora #spacewx #CIRES

Don't forget to pause and enjoy the small things! For example — Ice formations under a setting sun in Anchorage, Alaska. Photographed during the Navigating the New Arctic Community Meeting in November 2022. @arctictogether.bsky.social #PhotoFriday 📸: Taylor O'Brien/CIRES alum

A new generation of early-career polar professionals came to Boulder, CO this spring with a vision to transform how polar research is conducted, funded, and shared with the world. The results are now available in a comprehensive synthesis report buff.ly/iZnxw4o #PECWS @polarsecco.bsky.social

This week, CIRES’ Earth Lab celebrates 10 years as a leader in environmental data science and education. "It's awesome to see a vision transformed into reality,” said Virginia Iglesias, Earth Lab director. @earthlabcu.bsky.social

We are proud of CU Boulder Department of Geography and CIRES PhD student Ethan Carr (third from the left) who was selected as one of 12 Climate Youth Champions from nine countries as part of the inaugural cohort of the Hindu-Kush-Himalaya - Arctic Youth Leadership Forum. buff.ly/qeNTBuA

Dark winter Arctic nights are getting warmer -- and clouds are to blame. @cires.colorado.edu and @brookhavenlab.bsky.social found wintertime clouds are becoming more opaque, and both ice and liquid-containing clouds are trapping more heat instead of letting it escape to space. buff.ly/qYVv0qa

Here's a visual of how Hektoria Glacier started to disintegrate in 2022. #CIRES #Antarctica

This video shows how Hektoria Glacier began to disintegrate in 2022. #Antarctica #CIRES

New video: A glacier on Antarctica’s Eastern Peninsula experienced the fastest retreat recorded in modern history—in just two months, nearly 50 percent of the glacier disintegrated. Watch this video to understand what happened. Study by @ciresnews #Antarctica #glaciermelt

In just two months, nearly half of Hektoria Glacier on the Antarctic Peninsula disintegrated — retreating 8 kilometers, the fastest glacier retreat ever recorded in modern history.

In his Boulder Daily Camera Opinion column, @maxboykoff.bsky.social notes the similarities between Hurricane Melissa in 2025 and Hurricane Mitch in 1998. "27 years separate them, yet climate connections persist." Paywall: buff.ly/5JUr8pl #hurricanemelissa

While October cold fronts and fire weather aren’t new for Colorado, climate change is influencing the conditions that increase the risk. Conditions now stretch longer into fall. Parts of Colorado now experience 1 to 2.5 months more wildfire-weather days than in past decades.

@Yale.bsky.social Climate Connections features a quote from Joel Lisonbee @nsidc.bsky.social: When drought meets deluge. Climate change is intensifying both floods and droughts – sometimes leaving communities to endure both burdens at once. buff.ly/JreAfiD #drought #climatechange #floods

From January to April, an upwelling of cold water along Panama’s Pacific coast typically cools corals and nourishes the marine food web. In 2025, for the first time on record, this upwelling didn’t occur.

New analysis! Paris Agreement commitments would help the planet avoid some really really really really bad heat impacts by 2100. But still would cause really really bad heat impacts compared to now, AND would fall short of Paris Agreement goals. www.climatecentral.org/report/10th-...
