With the different mechanisms for Methane release like slumping or earthquakes having the ability to release methane quickly, would it be possible for the 50 gt methane release to take place overnight or would an extremely unlikely event have to take place for that to happen?

Would the increase in transport of the ice down into the Fram not affect this though? The map below illustrates this.

Thought I would bring up an Arctic News article which describes, what they describe, the possible beginnings of Runaway Global Warming with high levels of Methane over the Laptev Sea and East Arctic Shelf. http://arctic-news.blogspot.ie/2013/10/epic-methane-releases-from-east-siberian-arctic-shelf.html#comment-form If I am right we had levels similar to these Methane levels last year over that location, but I could be wrong on that. The best evidence I have for this comes from a past article from Arctic News: http://arctic-news.blogspot.ie/2012/12/high-methane-levels-persist-in-december-2012.html Here is what is on Methane Tracker for October 24th 2013.

Forgive me, but I am having trouble understanding this post in that I wonder if you are claiming that the dimming effects of the comet are likely to have a much more significant impact in winter than in Summer? If I have completely read your post wrong then I apologize.

I guess we will have to wait and see, otherwise it's possible that the ice may not have record increases in extent during the refreeze season.
