Over the next millennia, 👉this gives rise to a sea-level increase of up to 40 m in our experiments👈, stressing the importance of including the committed #Antarctic sea-level contribution in future projections."

The long–term sea–level commitment from Antarctica

Abstract. The evolution of the Antarctic Ice Sheet is of vital importance given the coastal and societal implications of ice loss, with a potential to raise sea level by up to 58 m if melted entirely.

However, 👉future ice-sheet trajectories remain highly uncertain.👈 One of the main sources of uncertainty is related to nonlinear processes and feedbacks of the ice sheet with the Earth System on different timescales. Due to these feedbacks and the ice-sheet inertia, ice loss may already be triggered in...

For >30 years, the world’s largest #iceberg was stuck in the Antarctic. 5X the size of NYC’s land area & >1k feet deep, the mammoth piece of ice became loose in 2020 & began a slow drift toward the #SouthernOcean.

Now, #A23a, as it’s known, is spinning in place.
After leaving #Antarctic waters, the iceberg got stuck in a #vortex over a seamount….
