Strong Arctic sea-ice growth this year

Guest Post by Javier

February is not over, and Arctic sea-ice extent is already over half a million square kilometers higher than last year at this day.

The growing season has not ended, and 2019 Arctic sea-ice extent is already higher than the previous four years and six out of the last 14 years.

Arctic sea-ice has stubbornly resisted the very warm years between 2015-2017 caused by the big El Niño. Are we going to see an increase in Arctic sea-ice over the next few years? Only time will tell, but the idea cannot be discarded.

Antarctic sea-ice is also growing this year with respect to last year, so global sea-ice extent is going to see an important jump this year.

Stay tuned for the March results but the “Arctic melting pause” is alive and kicking 12 years later. It started the year Al Gore said Arctic sea-ice was doomed. Talk about timing.
