This video shows three X-class solar flares (strong emissions of electromagnetic radiation) on the Sun on November 9, 10, and 11. The associated coronal mass ejections (streams of hot solar plasma) streaming towards Earth disrupted Earth's magnetosphere and triggered auroras as far south as Florida.

Moving people and equipment during fieldwork can be difficult during the best of times. For the MOSAiC team, inclement weather, polar night, and their location directly on the sea ice provided unique challenges for transportation. #FieldworkFriday

Even in total darkness, the Arctic is getting warmer — and clouds are part of the reason why.
A new study analyzed 26 years of winter data from Alaska’s North Slope, and revealed that increasing cloud opacity — clouds becoming thicker and denser — is trapping more heat near the surface.

Many of us were treated to a spectacular light show from the Aurora Borealis last night! This was the view from Erie, Colorado, looking northwest. Cross your fingers for a cloudless night, and check the Aurora forecast from the www.swpc.noaa.gov/communities/.... #aurora #northernlights #cowx

Smart forest management pays off. New research shows that forest thinning and prescribed burns not only reduce wildfire risk but also deliver billions of dollars in economic benefits. Study by University of California-Merced and @cu-esill.bsky.social Min Gon Chung news.ucmerced.edu/news/2025/th...

We salute the Joint Base Lewis McChord and the 109th Airlift Wing that support @CIRESnews research in the Arctic and Antarctica. They brave the cold and push the limits to deliver critical supplies, personnel, and equipment to the ends of the Earth for vital research on frozen lands! #veteransday

"One glacier's 'Out of this world' retreat might have set a modern record. Now, scientists pieced together what happened," CIRES research posted by the Smithsonian Magazine. Story: buff.ly/gytQpc1

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

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.
