Topic: Sea ice

A shoreline view of Lake Michigan, just north of Muskegon, Michigan, on February 11, 2024. Though small chunks of ice dot the sandy beach, there is little-to-no ice coverage on the lake. Usually in February, the ice would be many inches thick at this same location, and the waves would be well off shore.

HUARINA, BOLIVIA – SEPTEMBER 29, 2023: An aerial view of a boat stuck in the dried lake bed of Lake Titicaca. The water level of Titicaca, the largest lake in South America, has been dropping drastically due to the unprecedented winter heat that hit the country. September 2023 was the warmest September on record for South America and the globe.

Adapted from NSIDC’s Sea Ice Index, this map shows sea ice concentration on June 27, 2023. Concentration is color coded, with white representing solid ice and dark blue representing open ocean. For reference, this map includes the median ice edge for 1981–2010: half of the years had smaller extents, and half had larger on this date.
