Nothing in my comment was in reference to the clathrate hypothesis. My comment was about methane production that is actually occurring due to ancient organic matter that is/was frozen that is now fermenting as the permafrost thaws. In the Arctic circle the land is belching out huge quantities of methane right now. Pockets have formed and exploded, sending bedrock flying a half mile in each direction. Lakes are bubbling out methane profusely. You can poke a hole in the ground and lite a fire.

100% fact.
