Eleven trillion tonnes, seas rise

about 2 months ago

An IMBIE study supported by ESA and NASA found Greenland and Antarctic ice sheets lost more than 11 trillion tonnes since 1979, accelerating sea‑level rise and heightening coastal flood risks.

47 years of average annual sea ice thickness across the #Arctic... 🌊❄️🥼

Graphic now available to include 2025 at: zacklabe.com/arctic-sea-i...
Collection of small polar stereographic maps showing the average yearly Arctic sea-ice thickness for each year from 1979 to 2025. There is large spatial variability, but a long-term decreasing trend. The thickness of ice ranges from 0 meters to more than 5 meters.

“The ice sheets lost 11,309 ± 565 billion tonnes of ice between 1979 and 2023, with glacier dynamical imbalance driving 84% of the ice loss and surface mass balance the remainder.”
11 trillion tonnes…
If you spread that over Australia it would be 1.6m thick.

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?

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?

Satellite data shows major ice losses for Greenland and Antarctica
New research based on satellite data going ​back to the 1970s has documented major polar ice losses in Greenland and Antarctica — home to Earth's two ‌great ice sheets — that have contributed to rising global sea levels.

Climate change likely to have helped trigger Nepal glacier collapse, scientists say
Climate change is highly likely to have contributed to the catastrophic glacier collapse that flooded parts of Nepal and Tibet in late August, killing around 1,400 people and ​leaving thousands still missing, scientists said on Thursday.
