The Science Is Not Only Settled: It’s Just Starting!

Seasonal Change in Antarctic Ice Sheet Movement Observed for First Time

Phys.org | Oct. 6, 2022

Some estimates of Antarctica’s total contribution to sea-level rise may be over- or underestimated, after researchers detected a previously unknown source of ice loss variability.

While it is not unusual for ice flow in Arctic and Alpine regions to speed up during summer, scientists had previously assumed that ice in Antarctica was not subject to the same seasonal movements, especially where it flows into large ice shelves and where temperatures are below freezing for most of the year.

Assumed.
