From the Guardian - emissions of the powerful greenhouse gas from coal, oil and gas are up to 60% greater than previously estimated, meaning current climate prediction models should be revised, research shows
"The fossil fuel industry’s emissions of a powerful greenhouse gas are dramatically higher than previously thought.
Researchers who pulled together the biggest database yet of worldwide methane emissions found that, after natural sources were discounted, emissions from gas, oil and coal production were 20-60% greater than existing estimates.
Methane makes up just 16% of global greenhouse gases and is shorter-lived than the CO2 which accounts for three quarters, but has a much more powerful warming effect.
The extra methane estimated by the study is 300 times larger than the amount leaked in California’s Aliso Canyon last year, which was the worst gas leak in US history. While bad news for efforts to tackle climate change, the new study published in Nature also found that methane emissions had fallen as a fraction of industry’s production."
