Melt Methane hydrates = Doomsday??

One more bad news, global warming brings another potential catastrophe for our planet, namely the melting of methane hydrates: methane hydrates stored in the form of ice. The number is quite astounding 3,000 times the methane currently exists in the atmosphere.


Planet Earth matana store frozen in a very large number called methane hydrates or methane clathrates. Methane Hydratesbanyak found at the North Pole and South Pole, where the surface temperature of 0 degrees Celsius, or the sea floor at depths of more than 300 meters where the water temperature is 2 degrees Celsius dikisaran. Methane hydrates are also found in deep lakes like Lake Baikal in Siberia.

Methane is a greenhouse gas with KAA 23 times more damaging than carbon dioxide (CO2), which means that this gas konstributor very bad for global warming is in progress.

The bad news is global warming causes the temperature of ice at the North Pole and South Pole to be getting hotter, so the methane stored frozen in the ice at both poles are also liberated into the atmosphere. Scientists estimate that the Antarctic save approximately 400 billion tons of methane frozen. This gas is released bit by bit into the atmosphere as more and more parts of the ice in Antarctica which collapsed. You can imagine how horrible this situation: If the Antarctic ice sheet losing all his, then the 400 billion tons of methane will be released into the atmosphere! This does not include frozen methane that are stored on the seabed are also threatened because of the heat melting temperature of the oceans due to global warming.

Once triggered, this cycle will result in global warming is so severe that perhaps can be compared to the apocalypse!

Is this a fantasy invented by environmental activists and scientists paranoid? Unfortunately not. Geological evidence that strong states have at least 2 times our planet experiencing this event.

Geologists have found that this great catastrophe had occurred about 55 million years laluyang referred to by scientists as the Paleocene-Eocene Thermal Maximum (PETM). At that time, bursts of methane rises to the surface and warming the planet resulting in very fast. This led to mass death and disturbing state of the earth's climate up to 100,000 years later.

PETM addition, this major catastrophe it had occurred 250 million years ago, at the end of the Permian period, in which methane blast wiped out almost all life on planet earth.

More than 94% of marine species that we now encounter as a fossil experiencing sudden extinction due to the low levels of oxygen. More than 500,000 years later, a few species are left struggling to survive in such hostile environment.

Then how North with our present circumstances? With the deposit of frozen methane enormous, with the amount of perennial ice in the polar regions are melting, with the heat of the ocean temperature, and the miraculous discovery of frozen methane Diman point began to gush into the earth's surface. So we really ought to worry!

It is time we took part in the development of efforts to stop global warming continues to occur. It is proven that we humans cause or major contributor glpbal experienced warming our planet. Let's take action! Let us not repeat the murky geological history has ever experienced this planet!
