Surge in Antarctic Sea Ice continues

The surge in Antarctic sea ice that occurred in the last week of February has continued, and at the start of May the sea ice extent in the Southern Ocean was 103.1% of the long-term average, that’s considerably higher than the 98.0% it was at the same time last year. As for the reason behind the surge I am no expert and couldn’t possibly comment! I would say that mean 12 monthly temperatures have been fluctuating in recent years (see my DIY reanalysis temperature anomalies below) in the Antarctic and still well above the negative anomalies that occurred in 2015, which may have been the reason for the surge in sea ice extent that year.

What do you think?
