3 massive changes you'll see as the climate careens toward tipping points Scientists are increasingly concerned that the planet is headed for massive, irreversible changes due to global warming. In some cases, those changes have already begun.

If we don't rapidly phase out fossil fuels, we can say goodbye to coral reefs, the Greenland and Antarctic icesheets, and permafrost. The results will not be pretty.

NSF sent about the same amount of money out as the previous year, but to about 20% fewer new recipients (8800 new grants this year vs. 11,000 last year). NIH did something similar.

I could be wrong, but I thought similar language is in NSF T&C's, right? Implemented during the first Trump administration?

Happy Polar Pride!

This year I'd like to draw attention to @500qs.bsky.social - an awesome campaign for making LGBTQ+ people in STEM more visible!

Coincidentally, happy to have played a part making Arctic Pride happen here in Tromsø last week 🏳️‍🌈 #polarpride #LGBTQinSTEM #DiversityInPolarScience

Happy Veterans Day! We don’t get Antarctic ice cores w/o skillful military air- & sea-lift. Operation Deep Freeze is important for US science & national security, world-leading in polar ops for 70 years.

📸 Ice cores loaded into an LC-130H at WAIS Divide, West Antarctica, 2009-10 season.

Thanks - and more importantly, thanks for collating/sharing!!

Hey ice sheet types! 👋

The memes about the insane number of starter packs on this thing motivated me to create one more.

Please let me know who I am missing from the ice sheet world. 👇

Satellite Data Reveal Changing Lakes Under Antarctic Ice - Eos Radar altimetry observations have pinpointed 85 active subglacial lakes, shedding light on how water moves beneath the Antarctic Ice Sheet.

A new analysis of #CryoSat-2 data revealed that subglacial lake levels in Antarctica are changing not by centimeters but by *meters*.

I love how much this piece lets the readers nerd out (along with the journalist) about what processes may be at play with this retreat!

❄️ Calling all glaciology PhD students! ❄️

Applications are now open for next year’s Karthaus Summer School. It’s a great experience and you will be very well fed. Apply here: www.projects.science.uu.nl/iceclimate/k...

Trying to get more connected on here - any (other) glaciologists / snow scientists / sea-ice scientists / cryo-neds on this app that I should be following? Tag your cool friends! (Yes, that pun was intentional.)

How exciting!!

Letter from the IGS President Shin Sugiyama announcing the new Secretary General, Allen Pope, and thanking the outgoing Secretary General, Magnus Mar Magnusson. Followed by a letter from Allen Pope, who feels excited, as a glaciologist, to be appointed in this community-facing role, and who thanks Magnus for his leadership and for his help during this transition period.

Thanks so much, Ryan!

Thanks so much, Dan!! Big shoes to fill. Hopefully I’ll get to join y’all at NWG sometime!!

Career update: I’m excited & honored to be @igsoc.bsky.social's new Secretary General! I’m particularly excited to return to my roots as a glaciologist in this community-facing role. As I’m getting up to speed, feel free to reach out & see you at IGS meetings and publishing in IGS journals soon?!

An avalanche?! Looks like perfect weather!!

SO many good nerd friends!

And with Antarctica on top, no less. (Which is also consistent with Mātauranga Māori that I've seen presented.) I love it!

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! 🔥📈

In three days, our iconic red planes will take off from Canada to make the epic journey across the world to Antarctica.

These flights mark the start of a new polar science season.

BUT ALSO that means there's three days left to send your name to Antarctica with us! tickettoantarctica.com
