New piece on the blog on the new #IMBIE paper. How healthy are the ice sheets? What is driving their mass change and what do we know now after a half a century of observations by satellites? #iceSheets #SeaLevelRise #ClimateChange #ClimateImpacts #EO #SatelliteData

Half a century of ice loss: the new IMBIE dataset

A big new community paper has just landed: the IMBIE paper is a big effort to assess the long term health of the ice sheets. What did we find and what does it mean?

“... far too warm” (1.5°C) is indeed correct: we already know that even today‘s warming is sufficient to trigger the collapse of the West Antarctic Ice Sheet in the long term. The ‘safe limit’ is below +1°C of global warming! #ClimateCrisis #SeaLevelRise #IceSheets #WAIS #Collapse #TippingPoints
Screenshot showing an excerpt from the new paper by Stokes et al. titled "Warming of +1.5 °C is too high for polar ice sheets" with some parts of the text highlighted.

Scientists show that +1.5 °C is far too warm for Earth's ice sheets and will result in several metres of sea-level rise over the coming centuries, extensive loss and damage to coastal populations and will challenge the implementation of adaptation measures www.nature.com/articles/s43...

If case you missed it, the recorded (& lightly edited) livestream with the director of the Climate Extremes: At The Abyss? documentary is now available at the same link below! #ClimateExtremes #EarthSystemDynamics #TippingPoints #AMOC #AmazonRainforest #IceSheets

Friday, I'll host a livestream with the director of a new #climate documentary discussing the complex science of Earth system "tipping points" & the challenge of assessing (rising) risk of reaching them in a warming world. Join us live @ 10am PT 10/25: www.youtube.com/live...

This plot on wikipedia was made by @RARohde based on data published in late 90s and early 00s. Wondering if this has been updated or if there is new understanding on any of these palaeo records? #Palaeoclimate #SeaLevelRise #IceSheets Maybe @DrEvanGowan has thoughts? Anyone else?

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...

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 ...

A “glacial forebulge” is a long hill that forms in front of an ice sheet.🧊 In @eos.org, the authors of a recent review article give an overview of glacial forebulges, how scientists study them, and what questions remain. 🔗 buff.ly/UAsL19M #AGUPubs #Glaciers #IceSheets #Geology #Earthquakes

How Glacial Forebulges Shape the Seas and Shake the Earth - Eos

A glacial forebulge is a bending-related upheaval of the lithosphere that has a strong effect on the sea level change pattern and on lithospheric stresses, which can induce intraplate earthquakes.

Last month saw a very large temperature anomaly gradient between the Weddell Sea region and West #Antarctica. In fact, this was one of the very few places anywhere on the globe with colder than average temperatures in August, especially compared to older baselines (e.g., 1951-1980). Data from ERA5.
Polar stereographic map of 2-m air temperature anomalies in the Antarctic for August 2026. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. There is a lot of variability in the pattern of temperature anomalies across the continent. Anomalies are calculated relative to a 1981-2010 baseline.

“...when #icesheets melt, they contribute to rising global sea levels. And with every additional centimeter of sea-level rise, about 2 to 3 million people are put at risk of annual coastal #flooding.” www.commondreams.org/news….

Antarctic, Greenland Sheets Have Melted Enough Since the '70s to Cover US in 5 Feet of Ice | Common Dreams

Greenland and Antarctica's ice sheets have lost about 11.3 trillion metric tons, or 12.5 trillion US tons, since the 1970s.
