Interesting new preprint from @colinrmeyer.bsky.social and colleagues -> “we perform transient model experiment…to determine the effects of water extraction on glacier velocity. With continuous pumping, we simulate a modest impact on velocity…” egusphere.copernicus.org/preprints/20...

A great explainer on @dgrau13.bsky.social’s recent paper finding simple equations describing the size of melt lakes on ice sheets doi.org/10.1038/s414...

Glaciers in California’s Sierra Nevada are likely disappearing for the first time in the Holocene! 🧊😲 What a surprise! (nope) 🙃 Another evidence we are leaving the climate crucible that saw human societies develop! 🔥📈 www.science.org/doi/10.1126/...

What humans do to change climate matters much, much more than natural climate variations in determining future ice loss from Greenland 👉 Read about the results of the Greenland Ice Sheet Large Ensemble (GrISLENS) Project in our paper out now in The Cryosphere doi.org/10.5194/tc-1...

My first thing, pretty much, pretty pleased with it eartharxiv.org/repository/v...

📣 Our new paper is out in Nature Communications! Subglacial water—often overlooked—can change sea-level rise projections by up to a factor of three. Big implications for how we model Antarctica. 🔗 www.nature.com/articles/s41...

We have an opening for a postdoctoral researcher to join us at Dartmouth College. The focus of the project is on snow sintering. Together we will develop new models for snow evolution on the surface of glaciers. Please feel free to reach out if you have any questions.

Here's more from @jtemple.bsky.social on what the stakes of a Thwaites glacier collapse are and why this initiative is so important

Come work with us at Arête Glacier Initiative! 👇 We are seeking a full-time Executive Director (equivalent to CEO) to help lead and grow Arête, a mission-driven non-profit cofounded by Colin Meyer @colinrmeyer.bsky.social and me. drive.google.com/file/d/12svQ...

Accepted in Journal of Glaciology! Work co-led with @subglacial.bsky.social testing glacier slip theory in the lab. We characterize new slip behaviors on short forcing timescales, while also finding theoretical models are reasonable over longer periods. www.researchgate.net/publication/...

One month until Christmas Eve 🎄🎅🏼 ❄️ The chance for a white Christmas is decreasing across Europe. 📉 Here’s how the odds for a snowy Christmas Eve have changed in the latest climatological period (1991-2020) relative to 1951-1980. 🧵 (1/3)

@leighstearns.bsky.social shining bright at #AGU24 telling the fascinating story of changes at Greenland’s Helheim Glacier Greenland since the 1940s. Advance and thickening up to the 1980s followed by retreat and thinning, all in response to warming atmosphere and ocean and adding to sea level rise

We spend a few months on the Juneau Icefield each summer conducting glacier, geophysics, Polar engineering, geoscience, & climate related research with the Juneau Icefield Research Program. We are open to other scientists joining our team so reach out if you are interested!

WOOHOO! 🥳 We’re a little over 7 years old and #EarthArXiv has reached 5000 pre- and post-prints! Thanks to all of those who have supported us over the years 🤗 Check out EarthArxiv for yourself at: eartharxiv.org and learn more about us here: en.m.wikipedia.org/wiki/EarthAr...

Hey #energysky, I decided to record all the lectures in my Sustainability Issues in Energy class this fall. I am posting them to my YouTube channel every Friday. Follow along here: youtube.com/playlist?lis... 🔌💡

One of the most frequent questions I'm asked as a climate scientist is, "what can we do about climate change?" I don't base my answer on the physical science of the climate system, but rather social science of how individuals can most powerfully effect change. I look to research such as this: 🧵

Sometimes it feels like nothing is changing: as if we’re climbing the tallest mountain in the world, and the summit is no closer than when we started. But if we stop for a minute and turn around and look back, we can see how far we’ve actually come. Progress is happening, step by step.

We've got recordings of essentially all public presentations and discussions from the recent Future of Greenland ice Sheet science workshop, now up and available to stream via www.fogss-workshop.org/2024-agenda Check it out! Talks from NASA, NSF, and leaders of major initiatives to inspire action

We usually compare GHG emissions and temperatures to pre-industrial times, often considered to be 1850-1900, partly because good records start aroung then. But Japan has kept good records of peak cherry tree flowering since 812! ourworldindata.org/grapher/date...

Thanks to all who took the time to chat sea level rise and ice sheet modeling this week! The coalition building I worked on made this the most fun and rewarding AGU in a while.

cryosky is growing! 🫡 🧊

I’m here! Thanks @colinrmeyer.bsky.social 🙏🏼

Is the community of 🌊 level projection experts too accustomed to working with the scraps off the 💰 agency tables? I firmly believe that if the right 👀 can see how insufficient sea level projections are, the money will come. $20M won't be too much to ask. Let's 💭 big! What's our dream ask?!??😎 1/

I'm just stunned that Chris Borstad has passed away. I can't believe it. So young. He was such a great guy- so fun to be around. And such a clever and accomplished early career scientist. He was also a hell of a good skier. So very sad. Love to his family. semaj545.wixsite.com/chrisborstad
