[quote:Anonymous Coward 27375240:MV8xNDQ3NzA2XzM0NDY4MDExXzQ2QUM2NTlC] Returning to the 4 GtC release scenario, assume such a release occurs over a oneyear period sometime in the next 50 years as result of slope failure. According to the Report of the Methane Hydrate Advisory Committee, “Catastrophic slope failure appears to be necessary to release a sufficiently large quantity of methane rapidly enough to be transported to the atmosphere without significant oxidation or dissolution.” In this event, methane will enter the atmosphere as methane gas. It will have a residence time of several decades and a global warming potential of 62 times that of carbon dioxide over a 20-year period. This would be the equivalent of 248 GtC as carbon dioxide or 31 times the annual man-made GHG emissions of today. Put another way, this would have the impact of nearly 30 years worth of GHG warming all at once. The result would almost certainly be a rapid rise in the average air temperature, perhaps as much as 3°F immediately. This might be tolerable if that’s as far as things go. But, just like 15,000 years ago, if the feedback mechanisms kick in, we can expect rapid melting of Greenland and Antarctic ice and an overall temperature increase of 30°F. For point of reference, the average temperature of the Earth (atmosphere, land and top layer of the ocean) in 2004 is around 60°F. The methane hydrate release projected here would raise the temperature to around 90°F or more. Such high temperatures would undoubtedly destabilize all of the other methane hydrates in the ocean and arctic permafrost, some 10,000 GtC or 620,000 GtC equivalent as carbon dioxide. This would have the impact of 78,000 years worth of GHG warming over a few decades. The temperatures reached and sustained would most likely cause a rapid die off in ocean phytoplankton and other sea life as well as most land plants and animals, including humans. The result would be a mass extinction and mark a major transition point in the Earth’s geological history. http://www.physics.rutgers.edu/~karin/140/articles/MethaneHydrates.pdf [/quote]

Its going around the ring... South America next.
For anyone interested in Earthquake predictions:
I guessed 2 that have hit by looking at the above link and seeing a pattern. I'm talking above 4.0 Mags. Please take a look and tell me where you think the next one is going to be and why.
