New research shows that reduced Antarctic sea ice in 2023 allowed heat to escape into the atmosphere, disrupting ocean circulation and increasing storm frequency, signalling potential long-term climate impacts
The research, published in the Journal of Glaciology, is the first large-scale study of its kind to compare ice shelf thickness data from ice-penetrating radar measurements to thickness data estimated from contemporary surface elevation measurements.
The global sea level rise linked to melting of the West Antarctic Ice Sheet has been significantly underestimated in previous studies, meaning sea level in a warming world will be greater than anticipated
