#IceSheets can collapse faster than previously thought possible

Ice sheets can retreat up to 600 metres a day during periods of #ClimateWarming, 20 times faster than the highest rate of retreat previously measured, according to a new paper.

[...]

»“Our research provides a warning from the past about the speeds that ice sheets are physically capable of retreating at,” said Newcastle’s Dr Christine Batchelor, who led the study. “Our results show that pulses of rapid retreat can be far quicker than anything we’ve seen so far.”«

Antarctica drips.
Climate's hourglass counting down.
Too bad no alarm.

Roth, will this be recorded and available for us plebs in the Antipodes to watch ? On either Perrtube (Fediverse) or Youtube ?

"New research finds that ice-sheet-wide collapse in West Antarctica isn't inevitable: the pace of ice loss varies according to regional differences in atmosphere and ocean circulation."

Excited to announce here that Poul Christoffersen will be joining the Institute for Marine and Antarctic Studies (IMAS) at University of Tasmania from March as Professor in Glaciology.

Poul will bring to Australia additional, and much needed, expertise and leadership in ice sheet and glacier science.

#introduction
I am currently an undergraduate at Oregon State University, studying Environmental Science, conducting research regarding ice/ocean interaction. Some of my interests are #paleoclimate #climate #climatechange #AMOC #transpolardrift #icesheets. I’m a huge fan of the Marvel Cinematic Universe and the TV series “The Big Bang Theory.”

How much #ClimateChange can #IceSheets take? Ice sheets are nonlinear systems, and are vulnerable to destabilizing feedbacks. When the climate changes beyond a certain threshold, these feedbacks take charge and either grow the ice sheet or "kill" the ice sheet – irreversibly until a new stable equilibrium is met. The W. Antarctic ice sheet is vulnerable to one of these feedbacks known as marine ice sheet instability.

Whether or not this is #Antarctica's future is up to us.

"Advances in satellite technology over recent decades have allowed scientists to chart the melting of the Earth’s ice sheets in remarkable detail."

"Meltwater on the surface that finds its way to the bottom of an ice sheet – and water that has been melted there directly – plays a key role in regulating ice sheet flow. Ultimately, this water can determine how quickly ice flows into the ocean and contributes to sea level rise."

"Yet, because satellite records only span a few decades, they cannot tell us how this process will respond to sustained global warming over the rest of this century and beyond."
