Methane and Climate Change



The rapid release of methane into the earth's atmosphere 635 million years ago caused rapid warming and mass extinction of species, disrupting the climate for more than 100,000 years.and may happen again in the near future, reported in Nature .

The concern is that it could take a relative small rise in temperature to start unleashing the gas, which would then trigger an unstoppable warming cycle.

The first evidence that millions of tons of methane 72 times more potent than carbon dioxide over 20 years is being released into the atmosphere from beneath the Arctic seabed has been discovered by scientists at Sep 2008 according to The Independent.

The livestock industry is the number one producer of methane which is the most potent greenhouse gases. The UN reports that meat production emits 37 percent of the world's methane gas.
