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. 🥹

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.

Petermann Glacier on the brink: Progress, challenges and insights

Yes, our review article on Petermann Glacier is even more topical with its recent calving event! Whether you consider Petermann to be an ‘ice stream’ or a ‘glacier’, might influence how you think about the stability of Northwest Greenland. 🤓

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.

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

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.

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!

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.

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. 👀

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.

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. 🔥📈🔥

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.
