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
