Facts About the Arctic in September 2020

A detailed dissection of the 2020 minimum of various Arctic sea ice extent metrics can be found on a dedicated thread. All other Arctic news in September will be found below. As is usually the case, let’s set the ball rolling by taking a look at Wipneus’s visualisations of the August PIOMAS gridded thickness data:

together with the computed volume:

and anomaly graphs:

PIOMAS volume at the end of August was still firmly in 3rd place behind 2012 and 2019.

However Arctic sea ice extent is firmly in second place behind 2012, although that does not also apply to area:

      How about this one instead?
