The rubber is starting to hit the road in our FirnMelt project 👇

Check out this wonderful explainer of the new CMIP7 climate scenarios written by @zekehausfather.com 👇 Get informed on how they differ from previous scenarios, and learn the new lingo and ambition of ‘Very Low’ — VL! 👊💙

The Kyoto Protocol was gaveled in 1997. The ‘climate time’ that has passed since then — full of worlds avoided, but also opportunities missed — reminds me of song lyrics about looking back at your adolescence and recalling its dreams about all the things you’d never be. Here’s to you, Kyoto. 🍻

This week’s failure in Addis Ababa to agree on a timeline for the next IPCC report is disheartening to everyone pushing climate science forward.

Full obstruction : no agreement on budget and timeline for #IPCC AR7

Sounds like the world needs ‘Don’t Look Up’ Part 2 … Dr. Zach Galifianakis playing principal investigator of a climate modelling group please! 🙏

Exhibit #73617 on the ‘benefits of climate change’ 🙄

I’m thinking of my U.S. research colleagues as their funding dries up. This isn’t just a financial crisis, it’s political decisions creating an existential moment for U.S. science. Many people are simply waiting — and hoping — this will pass, but returning to ‘the norm’ isn’t guaranteed. 🥹

If you are in Kangerlussuaq next week and want to learn more about our @firnmelt.bsky.social project, please see the open house below. 👇

Yes! The @firnmelt.bsky.social traverse equipment has arrived in Kangerlussuaq! We’re super excited to start instrumenting and measuring the near-surface properties of the #Greenland ice sheet! 🤓 Funded by @erc.europa.eu

Stopping regulation of climate-polluting gases from U.S. power plants would be profoundly short-sighted. These emissions harm public health today, and put future generations at greater climate risk.

Yes, the AR7 WGI expert review period is still ongoing. 👇 Climate experts, please consider if you can help make the next IPCC assessment report as comprehensive and insightful as possible. 🤓

Here’s some fantastic thermal drone imagery of a thermal spring in East Greenland. Captured by Eva Nielsen earlier this month. The spring water is 53C, flowing down a rock wall behind the field team. Our HotBlink project is funded by the Independent Research Fund of Denmark.

Top climate scientist telling us to brace for an El Niño the likes of which we haven’t seen before… 👇 You can get it straight from the source himself at: @drjamesehansen.bsky.social

Hey! Team FirnMelt is looking for a PhD student ⤵️

Engineering the ice sheets to limit their sea-level rise contribution is a drastic idea, but it could be on the menu in an ‘all of the above’ response to accelerating climate change. This talk from former IGS President Doug MacAyeal swayed me on the topic. ⤵️ youtu.be/E0TGF_zDtCw

Yes, American science continues to trundle headfirst into an “evolve or die” era. Thankfully, lots of bright climate folks are finding ways to move the ball forward without relying on the U.S. government. 💙✊

Calling themselves ‘Greenland Energy’ is simply Greenland-washing old fashioned Texas-based oil-and-gas exploration. Greenland — and the world — deserves better than US neo-imperialism. A ‘frontier mentality’ for resource extraction challenges our rule of law.

Yes! We're super excited to see the first-order draft of IPCC AR7 WGI open to Expert Review today! www.ipcc.ch/2026/07/06/i... 👉 Sign up to become an IPCC Expert Reviewer and help strengthen the science, broaden perspectives, and make the next assessment even better!

If you’re interested in working at Asiaq (Greenland Survey), our sister organization is currently looking for a data specialist, with special attention to cryosphere and climate competencies. 🇬🇱 asiaq.career.emply.com/en/ad/data-s... Closes August 16th. ⤴️

Good grief, this hits home.

With so much happening in the world, it's easy to lose sight of the steady creep of climate change. But every so often, it forces its way back onto the front burner, forcing us to consider our collective climate trajectory. 👀

It would be poignant — and easy! — to make a montage of people going about their normal lives with wildfires looming in the background. Perhaps a fitting homage to our climate inaction. 🥺 ‘Golf under fire’ is almost ten years old now!

Thinking about shifting your research in the natural and/or technical sciences to Denmark? This call generously supports everything from 1-yr sabbaticals to 7-yr relocations at many career stages. Phase 1 intents are due August 12. novonordiskfonden.dk/en/grant/rec...

Yup. Canadian wildfires are expected to worsen in the future, as our warming climate increases their frequency and severity. This is pretty much a statement of fact. Sadly.

Yes! Wildfire smoke seems to be everywhere at the moment. Here’s the Anthropocene sunset in Eastern Ontario this evening. 😶‍🌫️

Sadly, it’s no surprise that climate change is making El Niño events more ferocious. 🌊 Here’s IPCC AR6 Box 11.4 saying that extreme El Niños occur more frequently in a warming world. ⤵️ Still, the exceedance magnitude of this summer’s event beyond all previous events is eye opening. 👀

Dr. Alan Grant was the first depiction of a field scientist that I ever saw. The character opened my eyes to a career studying the natural world. 🥺

This heavy-handed policy is seeking to turn back the clock on years of international scientific collaboration. Climate change doesn’t recognize borders or geopolitics. Such global challenges demand global collaboration.

These specialized vehicles will support our FirnMelt project in researching the shifting fate of meltwater in the near-surface layers of the Greenland ice sheet and its effects on ice dynamics. Supported by @erc.europa.eu !

Definitely of relevance to all the fantastic researchers passing through Copenhagen these days!

Yes, Arctic wildfires are ‘new’, and sadly they form a positive feedback with climate change. Increasing wildfire activity is increasing the vulnerability of permafrost to thaw, accelerating the release of long-stored greenhouse gases. This is a feature, not a glitch, of the Anthropocene. 🔥📈🔥

These are the types of actions that determine our ‘worlds avoided’ or ‘opportunities missed’. We owe ourselves—and future generations—better. Shame on Duke Energy. #ClimateAction

…and it’s a damp heat! 🥵

I don't care. Shut down the bitcoin farms first.

Climate science seems like an abstract profession—until you're writing the next IPCC report in the middle of an extreme weather event. 🥵

Full endorsement of Bethan’s reflection on the state of the AR7 process here. No notes. 🫡😂

I have many happy memories of Athabasca Glacier, but sadly it is perhaps now a candidate for the glaciercasualtylist.rice.edu — It is <i>very likely</i> ‘critically endangered’ under all plausible climate scenarios.

Two very different tales of expectations meeting reality. ⬇️ #ClimateAction

Hey Copenhagen folks! 'ICE WOMEN' is screening in town on the evening of June 11. The documentary looks at the history of Arctic science from a female perspective. Tickets are free, but register in advance. Register: forms.cloud.microsoft/e/66QtbGrxjW Trailer: www.youtube.com/watch?v=MgBB...

Hey Folks! 👋 Please share that our Department of Glaciology & Climate is hiring a new technician (full time/permanent) to support our ice-sheet monitoring projects. Application deadline 3 June 2026 ⤵️ candidate.hr-manager.net/ApplicationI...

Yes, folks! The FirnMelt team is at #EGU26 this week, but you can also learn more about the ambitions of our project right here! 👇
