Global sea ice extent is no longer at a record low for the date, thanks to a quick freeze-up in the Arctic and a slightly slower decline in the Antarctic. The Antarctic sea ice extent in October 2023 was smaller than average, except for the Amundsen-Bellingshausen Seas and parts of the Pacific Ocean sector. The Arctic sea ice extent is currently the 7th lowest on record, with October 2023 being the 7th lowest on record as well. The Antarctic sea ice extent in October 2023 was the lowest on record, 1,900,000 km² below the 1981-2010 average. October also set a record for globally-averaged sea surface temperatures. Researchers have found unexpected life under Antarctic ice.

#Arctic sea ice extent is currently the 7th lowest on record (JAXA data) • about 30,000 km² above the 2010s mean • about 750,000 km² below the 2000s mean • about 1,370,000 km² below the 1990s mean • about 1,650,000 km² below the 1980s mean Plots: https://t.co/tBkW5GBOxd https://t.co/3ONV5F1Q8f
Antarctic Sea Ice Reaches a “Record-Smashing Low” https://t.co/5aokgL68IR
October continued to set another striking record for globally-averaged sea surface temperatures... Data available from @NOAA ERSSTv5 (https://t.co/V8F2MhaASY). Methods detailed in https://t.co/59vZAgOX5j. https://t.co/P6P5xZYgs8
October 2023 #Arctic sea ice extent was the 7th lowest on record. This was 1,980,000 km² below the 1981-2010 average. October ice extent is decreasing at about 9.50% per decade. Data: @NSIDC. https://t.co/2aTYQ23oeo
🚨 Yet again, another record. Last month averaged the lowest #Antarctic sea ice extent on record for the month of October This was 1,900,000 km² below the 1981-2010 average. Data from @NSIDC. https://t.co/JjkDfr4mVg
#Arctic sea ice extent is currently the 7th lowest on record (JAXA data) • about 100,000 km² above the 2010s mean • about 760,000 km² below the 2000s mean • about 1,430,000 km² below the 1990s mean • about 1,680,000 km² below the 1980s mean Plots: https://t.co/ysoGwwYtqb https://t.co/4xYvN7b7z7
Most of the #Antarctic sea-ice edge was smaller than average in October 2023, except for the Amundsen-Bellingshausen Seas and parts of the Pacific Ocean sector. Data from https://t.co/ydZwSgdnwa. Concentration = fraction of sea ice in a location. https://t.co/sYV5uh8Cgh
Future increases in ice-shelf melting in the West Antarctic over the 21st century may be unavoidable, suggests a study published in @NatureClimate. https://t.co/eQdmWSXWSZ https://t.co/XrIluVk7qQ
For now, global sea ice extent is no longer a record low for the date thanks to a quick freeze-up in the #Arctic and slightly slower decline in the #Antarctic to start their melt season. More sea ice graphics available at https://t.co/ecHYax1KfT https://t.co/jN8KsMVURL
