FEEDBACK made Kirkus Reviews top 100 indie #books of 2024! Which makes it a perfect #Christmas gift or even just a treat for yourself 🙂

It's a book about #nature, #science, and #philosophy, but mostly it's about who we are and why we do what we do. 🧵 1/11 📚💙👀

That was a blast! Really engaged audience and lots of deep questions. Very grateful for the opportunity to talk to a group like this, and I came away with lots of new contacts 🙂

At Parliament later today to present to the ministers some of our work addressing sea level rise and its impacts in New Zealand. Looking forward to seeing what level of interest there is...

Title slide for a presentation titled, "On the up: Global sea level rise and its socio-economic impact on Aotearoa New Zealand" to be given at the NZ Parliament. Slide shows a main graphic in steelblue of a curled fern leaf that is also a breaking wave.

Any philanthropists out there that would like to support some Antarctic-focused climate change & ecosystem science? I have some ideas, and a great team...

It is almost impossible in the current climate to get science funded, especially investigator-led basic research. There are zero options left now, except regular Marsden which is so broken it's not even worth bothering with.

So sick of this NZ govt. Last year I started writing a proposal for a $5M Endeavour grant. Then the govt cancelled them. This year I started putting together a $3M Marsden fund council award proposal and, guess what? Yes, govt cuts now mean these have just been canned too. FFS.

Yeah, I think one first author per year would be reasonable. Either way, anything that can help reduce the overwhelm of trying to keep up with the insane number of new papers would be welcome...

One of the most sensible suggestions I've heard in a long time. Publish less, but better. #academicsky

🚨 New paper alert 🚨

We developed the new PanAntarctic model and assessed the sensitivity of Antarctic Bottom Water (AABW) formation and export to horizontal model resolutions of 1/10°, 1/20° and 1/40°.

This weekend a lot of the world is experiencing very high maximum temperatures. But the anomaly from long term climatology is more alarming. What the hell is happening across #Antarctica at the moment? Data from climatereanalyzer.org

Map of global max temperatures for Saturday June 28th, from climate reanalyzer website. Map shows very high values across USA and Europe, as well as equatorial regions.

Sure, I reckon with enough models we can get whatever answer you need 😉

For anyone not on Cryolist, today we announced a new regional-scale #ice sheet model intercomparison project focused on the Wilkes Subglacial Basin of East #Antarctica. Feel free to share and of course get in touch if you're interested in participating!

In addition, I find that the non-periodic phase of the logistic map can be usefully appropriated to represent a glacial maximum climate state - a state far from equilibrium that is highly susceptible to perturbation.

In this paper I use a cellular automaton to argue that the transition to asymmetric 100kyr #climate cyclicity may have arisen due to increasing coupling & #synchronization of #earth system components. Sync emerges from deterministic #chaos.

Alison Banwell, a glaciologist at the University of Colorado Boulder, led research into how ring fractures (aka “ice doughnuts”) contribute to the rapid collapsing of ice shelves in Antarctica. @alibanwell.bsky.social #WomensHistoryMonth

Antarctic Ice Doughnuts May Hold the Key to Shelf Collapse - Eos

The first direct record of ring fractures in Antarctic ice shows how the phenomenon could cause rapid ice shelf collapse.

Just to be clear (shouldn't have to say this, but...) I am definitely not 'anti-American'. I have many many great US friends and colleagues.

It's about not wanting to fund the current regime. Even to transit through a US airport you need to pay the govt for an esta.
