The Arctic Rain on Snow Study (AROSS) project, led by the National Snow and Ice Data Center (NSIDC), funded an award-winning StoryMap called "When Rains Fell in Winter," which tells the story of a Nenets reindeer herder named Tokcha Khudi and how a catastrophic rain-on-snow event impacted his annual migration on the Yamal Peninsula in 2013.

Antarctic sea ice has likely reached its minimum extent for the year, at 1.99 million square kilometers (768,000 square miles) on February 20, 2024, according to scientists at NSIDC.

Ice sheet surface melt on the Antarctic Peninsula abruptly dropped in mid-January and remained low through February 15. By contrast, melt day totals for the season were above average for the northern Larsen C and George VI Ice Shelves.

With the melt season well underway in the Southern Hemisphere, several ice shelves extending from the Antarctic Ice Sheet show above average melting, with significant melting in the Antarctic Peninsula region.

As of December 15, the Antarctic Ice Sheet had above average melt in the Amery and Dronning Maud Land Ice Shelf regions, with significant melting on the Antarctic Peninsula. Greenland’s 2023 melt season was the third highest on record.
