Huge fractures opening at the Thwaites Glacier Eastern Ice Shelf grounding line

A new and improved parameterization of the subgrid-scale effects of icebergs will enable realistic simulations of the future of the ocean around ice sheets. Led by postdoc Paul Summers and in collab with Rebecca Jackson, as part of the GLACIOME project! tc.copernicus.org/articles/19/...

Sub-grid parameterization of iceberg drag in a coupled iceberg–ocean model

Abstract. Ocean conditions in fjords play a key role in the accelerating ice mass loss of Greenland's marine-terminating glaciers. Ice mélange and icebergs have been shown to impact fjord circulation,...

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...

Georgia Tech College of Sciences@gtsciences.bsky.social · 9mo ago

New Paper Alert | Georgia Tech researchers developed a mathematical formula to predict the size of lakes that form on melting ice sheets. They discovered that lake depth and span are linked to the topography of the ice sheet. Their findings were published in @natcomms.nature.com.

🚨 New paper alert! Research by postdoc Maaike Izeboud from the bglacier group in Nature Climate Change 🎉 Using 20 years of satellite data, she mapped Antarctic ice shelf fractures and showed how damage rises under high emissions but stabilises in low-emission futures www.nature.com/articles/s41...

Damage development on Antarctic ice shelves sensitive to climate warming - Nature Climate Change

Damages such as crevasses or cracks can be early indicators of ice shelf weakening. Here, the authors quantify changes in damage structures in Antarctic ice sheets, which show sensitivity to warming

This fellowship was a huge part of the reason I am continuing to do climate science, and it has supported so many incredible people. These effects on early-career researchers, who do some of the most impactful work, is going to have long-lasting implications for science and scientists.

As of today, all current NOAA Climate and Global Change postdoctoral fellows have been furloughed due to the Dept of Commerce not releasing the funding for the program. In addition no new Fellows were awarded this year. cpaess.ucar.edu/cgc

The Secretary of Commerce's new policy requiring his personal review of all NOAA contracts over $100,000 is directly harming American science. 🧪 How do I know? Because this morning, twelve of America's rising leaders in climate science (including myself) were furloughed.

Finally: Aminat is looking for postdoctoral positions in ice sheet modeling - if you are thinking of hiring soon and looking for an experienced climate physicist and model developer, please reach out!

A nerdy science 🧵 to give you a break from the news: the first lead-authored paper by @gtsciences.bsky.social PhD candidate Aminat Ambelorun about “The Integrated Ice Sheet Response to Stochastic Calving”, now published in ‪the @igsoc.bsky.social‬ Journal of Glaciology doi.org/10.1017/jog....

The bottom line with the proposed cuts to NSF is to cut the number of working scientists and disappear opportunities to train new scientists. This is a PROPOSED budget to Congress. Call your reps.
