Methane bubbles climate trouble (BBC)

Thawing Siberian bogs are releasing more of the greenhouse gas methane than previously believed, according to new scientific research.
***
Methane's contribution to present-day global warming is second only to CO2.
***
"We show that methane flux from thaw lakes in our study region may be five times greater than previously estimated."
***
If a high release rate of a greenhouse gas is being triggered by rising temperatures, that will in turn stimulate still higher temperatures - a positive feedback mechanism.

Extra context comes from the age of the emerging gas. Using radiocarbon techniques, the researchers showed that some of the escaping methane molecules had been formed more than 40,000 years ago.

1. As if we don't have enough to think about....

2. Methane is a more effective greenhouse gas than CO2

But it has a shorter residence time. But then, of course, what does methane break down into? CO2!
We're so screwed...

3. Things are A LOT WORSE with Mother Earth then we are being told........

Screw the terrorists, this planet may soon no longer be able to support life.
