So all this el nino stuff has really been the earth working up to a really big fart?

lol

Sorry I had to go there.

I dont know how much of a problem its really going to be. There is no such thing as an endless cycle anyway when it comes to climatology. We also dont know how much methane is trapped in the crust, or in the sea floor (large methane emmissions have occured in the past from there as well periodically).

It is certianly something to look at. (IE keep an eye on)

Our main threat however isnt in the climate alone (which may or may not be within our power to fiddle with as of yet), its our massive unchecked population growth coupled with massive unrenewable rescource aquisition coming to a peak at a bad point for us survival wise which would be much harder at both signifigantly warmer or colder temperatures.
