Interesting (long) article mainly about the history of petroleum-based energy and the various potential disruptions (economic, political, climatologic) that could be caused by methane hydrate:

Estimates of the global supply of methane hydrate range from the equivalent of 100 times more than America’s current annual energy consumption to 3 million times more. A tiny fraction—1 percent or less—is buried in permafrost around the Arctic Circle, mostly in Alaska, Canada, and Siberia. The rest is beneath the waves, a reservoir so huge that some scientists believe sudden releases of undersea methane eons ago set off abrupt, catastrophic changes in climate. Humankind cannot tap into the bulk of these deep, vast deposits by any known means. But even a small proportion of a very big number is a very big number.
