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.

This lab is key for tracking deadly waves. Its sensors are about to go offline.

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/...

Earth’s strongest ocean current could slow down by 20% by 2050 in a high emissions future

Melting Antarctic ice is releasing cold, fresh water into the ocean, which is projected to cause the slowdown

*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

Evidence of active subglacial lakes under a slowly moving coastal region of the Antarctic Ice Sheet

Abstract. Active subglacial lakes beneath the Antarctic Ice Sheet provide insights into the dynamic subglacial environment, with implications for ice-sheet dynamics and mass balance. Most previously i...

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...

A fast and simplified subglacial hydrological model for the Antarctic Ice Sheet and outlet glaciers

Abstract. We present a novel and computationally efficient subglacial hydrological model that represents in a simplified way both hard- and soft-bed rheologies, as well as an automatic switch between ...

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?
