The cryosphere shapes sea levels, drives global weather patterns and supports ecosystems, but few of us get the chance to visit these stunning landscapes. So we're sharing some clips from fieldwork our scientists have undertaken in recent years 👇 #EarthDay #Cryosphere #NetZeroPolarScience

CIRES' @maxboykoff.bsky.social discusses the drop-off in climate change media coverage, including the potential impact of climate fatigue, on the Living on Earth radio program www.loe.org/shows/segmen...

There are lakes buried deep beneath the Greenland ice sheet we can’t see called subglacial lakes. 📽️ In this video CPOM's Professor Mal McMillan @lancasteruni.bsky.social explains how researchers working on the GLOBE project aim to track them 👇 🔗 youtu.be/ECv9FnnQf1k

“In the longer term, it’s the loss of capability, the ability to make these observations, because, like many things, it’s much easier to break than it is to reconstitute." CIRES Director Waleed Abdalati shares the impacts of the NOAA funding pause in @thehill.com ⬇️ thehill.com/policy/energ...

“Typically, snow at Niwot melts out by late May or early June. But this year, we're seeing near complete melt-off in mid April..." CIRES Fellow Jennifer Kay took students up to the Mountain Research Station to measure snow — there wasn't much there. @colorado.edu www.colorado.edu/today/colora...

🛰️Sunday is #HumanSpaceFlightDay - 65 years since humans first reached orbit. Satellite technology has transformed what we know about the cryosphere. Scroll down to read about just some of the CPOM science the space age made possible in recent years 👇 #HumanSpaceFlightDay #PolarScience

🌍It's #WorldHealthDay and the WHO is calling on everyone to celebrate the power of scientific collaboration to protect the health of people, animals, plants, and the planet. 🧊Understanding the cryosphere and how it is changing is a vital part of that story. #StandWithScience #WorldHealthDay

Colorado showed UP to help name our future passenger rail — and the results are in! Meet CoCo 🚆 25,000+ Coloradans voted, shared ideas, and helped shape what’s next for the Front Range Passenger Rail. This is our train, Colorado — and we’re just getting started.

Falljökull Glacier, or “Falling Glacier” in southeast Iceland, is known for its glacier hikes and ice caves. This photo is part of one of the largest organized (25,000+), publicly accessible glacier collections: NOAA@NSIDC’s Glacier Photograph Collection. https://nsidc.org/data/glacier_photo/

I dreamt last night that the peninsula had fallen off Antarctica into the Southern Ocean and I jumped off the continent into the freezing water to unsuccessfully try and save it. And this is this first post I see on bluesky in the morning. How odd.

Climate change impacts on the Antarctic Peninsula have global consequences. Great write up of our research in EOS. This is worth fighting for. eos.org/articles/ant...

Our new study discussing the future of the Antarctic Peninsula, led by @iceybethan.bsky.social, is featured in @agu.org’s Eos magazine today 🇦🇶 ❄️ 🛰️ 🧪 @cpom-uk.bsky.social @northumbriauni.bsky.social @cires.colorado.edu @nsidc.bsky.social
