The ice shelves, not all of Antarctica, gained ice.
I guess you could read the HN title and think, "see Antarctica must not be getting warmer if it gained ice." Where the shelves could have gained from the glaciers flowing faster off the land, and amount of ice could still have gone down.
- postalrat 3y agoWell did Antarctica gain ice or are you simply speculating?
- defrost 3y agoOverall Antarctica in total has steadily lost ice mass since 1990.

- chrisco255 3y agoOverall Antarctica in total has steadily gained ice mass since 4200 BC. Sea levels are currently 9 meters below what they were at that time.

- defrost 3y agoDid you read your linked paper? Figure 6. does not show total Antartica ice mass change, it shows a local area change in relative sea level markers. Today the relative sea level markers are much lower as the land itself is riding higher overall due to glacial rebound, the lifting of the land as a great weight is removed. Your paper (as discussed in the conclusion) argues that during the past 6,000 years a great deal of ice has been lost, having retreated some 30km and thinned by some 800m in thickness. Did you make a typo, or did you misunderstand your own linked source material? Either way, thank you for the paper.
