Temperature Spike and Sea Ice Loss on Antarctica's West Coast

Environment

Temperatures on Antarctica's west coast recently peaked 20C above average. This spike resulted in the loss of sea ice covering an area approximately the size of France. The scale of this temperature jump is startling. While the loss is significant, the precision of these measurements allows scientists to see exactly how these anomalies behave in real time. This clarity provides a more accurate foundation for the models used to understand the region's stability.

The post omits the baseline period used to calculate that 20C spike. A 30 year average versus a 10 year average changes the significance of the anomaly.

france is an area measurement but sea ice thickness varies wildly across the west coast.

i wonder if this coincides with those recent atmospheric river events... does this mean the seasonal recovery window is shrinking?

To Marie's point, high-resolution data from CryoSat-2 allows us to differentiate between surface melt and basal melting. This precision is why these anomalies are more useful for predictive modeling than previous coarse averages.

If the recovery window is gone, are we just watching the collapse of the West Antarctic Ice Sheet in real time? How long until this actually impacts sea levels in major coastal cities?
