The situation is very worrying, the more so since a huge amount of ocean heat is lining up to be carried into the Arctic Ocean by the Gulf Stream. On April 10, 2015, sea surface temperatures of 24.1°C were recorded off the North American coast (green circle), a +12.5°C anomaly, as the image below shows.
Malcolm Light comments: In this inverted blowup of the high temperature region you can see the expanded effect of methane hydrate detabilization along the Gakkel Ridge and the high temperatures caused by the onshore methane eruption vents (image below).
The situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog.
