More Falsified Climate Propaganda by Lying Evil Scientists

Arctic permafrost leaking methane at record levels

 

Experts say methane emissions from the Arctic have risen by almost one-third in just five years, and that sharply rising temperatures are to blame

 

Scientists have recorded a massive spike in the amount of a powerful greenhouse gas seeping from Arctic permafrost, in a discovery that highlights the risks of a dangerous climate tipping point.

 

…The discovery follows a string of reports from the region in recent years that previously frozen boggy soils are melting and releasing methane in greater quantities. Such Arctic soils currently lock away billions of tonnes of methane, a far more potent greenhouse gas than carbon dioxide, leading some scientists to describe melting permafrost as a ticking time bomb that could overwhelm efforts to tackle climate change.

 

They fear the warming caused by increased methane emissions will itself release yet more methane and lock the region into a destructive cycle that forces temperatures to rise faster than predicted.

 

Global warming is occurring twice as fast in the Arctic than anywhere else on Earth. Some regions have already warmed by 2.5C…

 

The new study, published in the journal Science, shows that methane emissions from the Arctic increased by 31% from 2003-07…The 31% rise in methane emissions there from 2003-07 was enough to help lift the global average increase to 7%.

 

The new study follows repeated warnings that even modest levels of global warming could trigger huge increases in methane release from permafrost. Phillipe Ciais, a researcher with the Laboratory for Climate Sciences and the Environment in Gif-sur-Yvette, France, told a scientific meeting in Copenhagen last March that billions of tonnes could be released by just a 2C average global rise.

 

…methane is pound-for-pound a more potent greenhouse gas, capable of trapping some 20 times more heat than CO2.
