After 5 long years, I’ve finally submitted my PhD thesis! Thanks to my supervisors Anya, @tobiasstl.bsky.social and Andrew for all their support and guidance. Off for a weekend trip to Montreal (avec des bagels et de la poutine) and then back to work on some long-shelved ideas. Je suis comblé!

Congratulations to @winnie-polargeo.bsky.social for earning an NSF CAREER grant to map temperatures at the base of the Antarctic ice sheet — the first project of its kind. This research will refine climate models and help predict future melt, protecting coastal communities. b.gatech.edu/3LyaveA

NOAA cut funding to the Alaska Earthquake Center, directed by my friend Mike West. As a result, seismic monitoring by nine stations in Alaska tracking tsunami-causing earthquakes will go offline by the end of the month. This endangers people in Alaska, Hawaiʻi, and other parts of the Pacific.

I am hiring 4 postdoctoral researchers for up to 4 years each. Topics include ice sheet reconstruction, GIA, spatial stats, and satellite geodesy. Based in Tasmania. All details are here: careers.utas.edu.au/en/listing/ with titles below I am also recruiting multiple PhD students (see below) 1/n

How much carbon budget do we have left if we want to stay below 1.5˚C? Just 2 more years at current rates. It is essentially impossible to avoid global temperature rise exceeding 1.5˚C. climatelabbook.substack.com/p/the-shrink...

My god, when you think it can’t get any worse…

New research out today with colleagues Bishakhdatta Gayen and Andreas Klocker projects that the world’s strongest current, the Antarctic Circumpolar Current, may slow by 20% by 2050 in a high emissions future. So happy to have this out for the world to read! www.theguardian.com/environment/...

Apply for a PhD in Antarctic microbial ecology 🦠🇦🇶❄️ with me, @greening.bsky.social and @arcsaef.bsky.social. We're interested in multi-kingdom interactions in terrestrial Antarctica, including mosses 🌱 with @antarcticmoss.bsky.social. Details www.findaphd.com/phds/project.... Please share widely!

Don’t let anyone tell you this guy is popular or that the country is trending his way. Just isn’t true. Never was.

*New evidence of active subglacial lakes under the East #Antarctic Ice Sheet!* We use #ICESat2 to show lakes fill and drain beneath slow-moving ice. Modelling likely meltwater routes suggests lakes discharge meltwater under ice shelves. tiny.cc/wsu7001 @npiglaciology.bsky.social

All NSF panels have been cancelled until further notice.

Kazmierczak et al present an efficient model that describes spatially and temporarily variable subglacial hydrology and geology, and their impacts on ice sheet flow in the ice sheet model Kori-ULB. This expands on a model I published last year. #ClimateChange #IceSheets 🧪🦣❄️ doi.org/10.5194/tc-1...

Summer over South Georgia. The glaciers pump millions of tonnes of sediments into the ocean which fuels a huge phytoplankton bloom sustaining one of the richest marine ecosystems on Earth. But as the glaciers recede and stop eroding, how long will this bounty last?

2025 really just a binfire of a start, eh www.theguardian.com/environment/...

First post on BlueSky to mark the end of my Antarctic fieldwork in Queen Maud Land working with @andrewmackintosh.bsky.social and some other wonderful scientists at @arcsaef.bsky.social. Overall, trip was hugely successful, with some exciting science to come. 1/4
