A Mishmash of Abrupt Climate Change Topics: Part 3 of 3 // Nov 6, 2020
My main focus is on the lack of Arctic sea ice regrowth in the Eastern Siberian Arctic Shelf region and the Laptev Sea region. These two regions faced extremely anomalous sea ice loss much earlier than normal in the Spring this year, and regrowth this Fall was much delayed.
Meanwhile, ice regrowth over the past week has set near record levels; basically unnoticed due to the US election distractions. The problem with the much longer ice free duration over these two Siberian shelves is that the water is over 5 C throughout the water column to the bottom, and thus the warmed sediments are thawing the enclosed methane hydrates, leaving large pock marks on the ocean floor, releasing methane that saturates the water column, and venting large amounts of methane into the atmosphere. Not a pretty picture.

‘Donald Trump had a grimace he held tight in his teeth,
And the anger and tension encircled his head like a wreath;
He had an orange face and a enormous round belly,
That shook, when he ranted like a bowlful of smellies.’
