A Little Ice News

NOAA says the continental US had its 6th warmest winter (DJF) on record for the continental US, while Alaska had the coldest February and winter in 21 years. February was 30th warmest. The Alaskan cold is definitely impacting Arctic sea ice extent,, but on the other hand it's very warm in Scandinavia and Siberia. It's not clear yet if Arctic SIE has peaked for the season, but when it does it will be no lower than 11th lowest out of 42 years.
Antarctic sea ice extent has passed its annual minimum, which this year ranked at 17th lowest. (Recent annual ranks have been 2017: lowest, 2018: 2nd lowest, 2019: 7th lowest.) Here's the record:

I'm not going to put a trend line through that because it's not obvious what it would be. (Linear doesn't seem appropriate.)
