Methane is initially a much more active green house gas. Initially 80x that of CO2 which it eventually breaks down into. I have seen numbers that over 100 years, about 20x CO2.

If it were all CO2, then we are talking about 10 years of our current man made emissions over the next 100 years. If mostly methane though then it could be like 200 to 800 years of our current emissions added to the next 100 years??

This might be an important detail.

PS this also does not mention releases from other methane hydrate stores in the ocean...
