Oil and gas production may be responsible for a far larger share of the soaring levels of methane, a powerful greenhouse gas, in the earth’s atmosphere than previously thought, new research has found. The findings, published in the journal Nature, add urgency to efforts to rein in methane emissions from the fossil fuel industry, which routinely leaks or intentionally releases the gas into air. They found that methane emissions from natural phenomena were far smaller than estimates used to calculate global emissions. That means fossil-fuel emissions from human activity — namely the production and burning of fossil fuels — were underestimated by 25 to 40 percent, the researchers said. Methane, the main component of natural gas, is of particular concern, because it can warm the planet more than 80 times as much as the same amount of carbon dioxide over a 20-year period.
