Methane Emissions On The Rise

The Australian | October 30, 2008

EMISSIONS of the potent greenhouse gas methane are on the rise again – but this time it’s nothing to do with farting cows.

Scientists have warned climbing methane levels may speed up global warming.

Levels of methane, the second-worst greenhouse gas after carbon dioxide, had plateaued but recently started to rise again.

Dr Paul Fraser from the CSIRO said increasing methane levels appeared to be caused by the melting of Arctic ice, which was opening up more wetlands to the sky.

These wetlands are releasing methane.

Cows and sheep, that burp, breathe and fart out methane gas, are a major source of methane emissions, but apparently, are not to blame for the increase.

Dr Fraser said the rise in methane levels was a concern.

“This is not good news for future global warming,” he said.
