Wow, I thought Al Gore was a fear machine...
The Canadian National Newspaper: "Over 4.5 billion people could die from Global Warming related causes by 2012, as planet Earth accelarates into a greed-driven horrific catastrophe...."
A recent scientific theory called the "hydrate hypothesis" says that historical global warming cycles have been caused by a feedback loop, where melting permafrost methane clathrates (also known as "hydrates") spur local global warming, leading to further melting of clathrates and bacterial growth.
In other words, like western Siberia, the 400 billion tons of methane in permafrost hydrate will gradually melt, and the released methane will speed the melting. The effect of even a couple of billion tons of methane being emitted into the atmosphere each year would be catastrophic.
The "hydrate hypothesis" (if validated) spells the rapid onset of runaway catastrophic global warming....
...There are enormous quantities of methane trapped in permafrost and under the oceans in ice-like structures called clathrates. The methane in Arctic permafrost clathrates is estimated at 400 billion tons.
Runaway Global Warming promises to literally burn-up agricultural areas into dust worldwide by 2012, causing global famine, anarchy, diseases, and war on a global scale as military powers including the U.S., Russia, and China, fight for control of the Earth's remaining resources.
