Global Warming causing methane release from Permafrost which causes even more global warming

This is a a blowup of a graph in Wikipedia under the heading permafrost: Since much of it is beginning to melt for the first time in likely thousands of years because of global warming it is releasing large amounts of methane which goes up into the upper atmosphere and helps create more greenhouse effect which in turn causes even more global warming. So, in this sense because of methane released from permafrost (if it isn't set on fire first by something) is causing more global warming.

So, maybe a way of saying this is: "Global warming is causing increased global warming".
