Very pleased to have been involved in this study, published today in a First Release version, which shows that the earliest large Antarctic Ice Sheet that developed about 33.7 million years ago did not extend to West Antarctica.

Have a great weekend! Here's your Friday ice update - #Arctic sea ice extent is currently the 6th lowest on record (JAXA data)...

• about 30,000 km² below the 2010s mean
• about 630,000 km² below the 2000s mean
• about 1,150,000 km² below the 1990s mean
• about 1,550,000 km² below the 1980s mean

More plots: zacklabe.com/arctic-sea-ice-ex

Line graph time series of 2024's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between April and July by looking at the decadal average line positions.
