Not scary at all

Maybe more articles of this nature, and things would actually start to happen.

Even scarier is the other sight, about 20 meters down off the coast of Santa Barbara, Calif.: bubbles, millions of bubbles of methane -- 20 times more powerful as a greenhouse gas than carbon dioxide.

The methane is bubbling up naturally from some of the enormous natural undersea reservoirs of the gas mostly locked into the frozen mud under the sea floor.

...

Scientists have just released video showing how, for the first time, they have been able to measure these natural up-wellings to tell whether, if large amounts of this methane ever thawed out from its deep sea beds, it would reach the atmosphere, rather than being absorbed in the water, and thus make the earth even hotter.

The findings of oceanographer Ira Leifer et al, published in a strictly peer-reviewed scientific journal, are that it would do just that.

In other words, all that undersea methane is a potential "positive feedback" of catastrophic proportions.

If warming currents, such as those already detected by scientists at depth, begin to thaw these methane beds, it will make the atmosphere, and consequently the sea currents, even warmer, and melt out more methane.

A number of scientists tell me that would take the Earth up into temperatures humankind has never experienced -- and probably could not survive.

As far as I can tell, this ran on ABC News. Now, at this stage in the game, maybe 18 Americans still get their news from ABC. But if we can convert just two of those, and they convert two, and those four each convert two...by 2080 we'll be good to go.
