Paul Beckwith's latest on Arctic methane

Paul Beckwith is back on-subject

Arctic Methane: A Catastrophe in the Making

Up to 2005, the oceans over the shallow continental shelves in the Russian Arctic (ESAS, Laptev) were ice covered, keeping the -100 meter deep oceans near freezing temperatures.

Since 2005, the ice cap cover has gone. The water has warmed as high as 17 degrees C there in summer, heating the sea-floor, perforating the permafrost cap, & thawing methane hydrates. Ebulition (bubbling methane) is rising up the water into the atmosphere in ever increasing amounts.

Here is another video Paul made earlier this week
