Latest measurements from those jittery, coffee-spitting folks at Environment and Climate Change Canada reveal that the ‘multi-year sea ice area‘ at Baffin Bay now shows ‘no trend‘ (1968-2018).
According to ECCC’s official website, multi-year sea ice corresponds to ice that has survived at least one summer’s melt — for the Canadian Arctic domain, the summer season is defined as the period from June 25 to Oct 15.
The latest data reveals that there is now no multi-year sea ice area trend in Baffin Bay from 1968 to 2018, thanks largely to the mammoth gains recorded last year.
In fact, 2018’s sea ice gains were the largest since 2010, and the third largest since 1998.
Furthermore, the recent ice expansion isn’t just confined to Baffin Bay.
In 2018, the average area covered by ice across all of Northern Canadian Waters was 1.23 million square kilometers, officially the biggest area since 2004’s 1.29 million km2:
As Norman Siefken points out on Twitter, “this data fully explains why the NW Passage never formed in 2018, and why vessels were instead diverted to Russia’s NE Passage.”
Waters in the furthermost northern latitudes are freezing up again, correlating neatly with the recent dramatic drop in solar output.
As we progress deeper into this next GSM, the ice will encroach further and further south.
