Spike in Methane Eliminates Climate ‘Benefit’ of Fracked Gas

The Guardian: “There was a huge global spike in one of the most potent greenhouse gases driving climate change over the last decade, and the U.S. may be the biggest culprit, according a new Harvard University study.”

“The United States alone could be responsible for between 30-60% of the global growth in human-caused atmospheric methane emissions since 2002 because of a 30% spike in methane emissions across the country, the study says.”

“The research shows that emissions increased the most in the middle of the country, but the authors said there is too little data to identify specific sources. However, the increase occurred at the same time as America’s shale oil and gas boom, which has been associated with large amounts of methane leaking from oil and gas wells and pipelines nationwide.”

“With the US responsible for as much as 60% of global methane emissions growth, it’s critical that the country reduce natural gas use as quickly as possible, said Robert Howarth, a Cornell University ecologist and methane researcher.”

“’There is simply no way to do that by reducing carbon dioxide emissions alone because of lags in the climate system,’ he said. ‘Even with major carbon dioxide emission reductions starting now, the planet would reach 1.5C in 12 years and 2C in 35 years. But the planet responds much more rapidly to methane, so a reduction in methane emissions now would slow the rate of global warming immediately.’”
