New scientific theory, hydrate hypothesis, suggests global warming 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. In fact, you should remember this moment when you learned about this feedback loop-it is an existencial turning point in your life...........
By the way, warmer temperatures and longer growing seasons have caused microbial activity to increase dramatically in the soil around the world. This, in turn, means that much of the carbon long stored in the soil is now being released into the atmosphere..........
To summarize, human activity is causing the Earth to warm. Bacteria converts carbon in the soil into greenhouse gasses, and enormous quantities are trapped in unstable clathrates. As the earth continues to warm, permafrost clathrates will thaw; peat and soil microbial activity will dramatically increase; and, finally, vast oceanic clathrates will melt. This global warming chain reaction has happened in the past.
Atmospheric concentrations of CO2 rose by a record amount over the past year. It is the third successive year in which they have increased sharply. Scientists are at a loss to explain why the rapid rise has taken place, but fear the trend could be the first sign of runaway global warming.
