Methane leak in Arctic: The Clathrate Gun Hypotheis
A few years ago I saw a documentary explaining the effects of methane leaking from the poles and the devasting consequences that they may have. I thought that I would unlikely live to see such an incredible phenomenon, but "unfortunately", I lived to see it: almost unnoticed this event has been shown on media: Big methane leaks detected on the Arctic by Russian ship. Such gas escapes, are a predicted effect in the "The Clathrate Gun Hypothesis". If this theory comes true, the consequence would be a global warming speed up, as methane inside on arctic permafrost is much more powerful than CO2 on greenhouse effect.
What’s more, the vicious circle in which the Earth climate would enter would be dramatic: global warming caused by human CO2 emissions provokes abnormal and fast ice melting from the poles; methane catched hundreds thousands of years ago leaks from poles permafrost; the greenhouse effect provoked by human CO2 is speeded up by the more powerful methane, increasing the ice melting and the methane leaking.
Of course, life on Earth will survive despite the dramatic and sudden changes: many species will adapt (although most of the species we know will not resist and become extincted). However we seem to cointinue ignoring the dramatic consequences and the global crisis for human living that will come when the great increase of Earth temperature decreases Eart’s capacity to support life and provide food.
