Oil and gas production is contributing even more to global warming than was thought, study finds
CNNCNN — Among greenhouse gases, carbon dioxide is the most significant contributor to global warming and therefore, public enemy No. Now, a new study finds that methane emissions from fossil fuels are between 25% and 40% larger than past research had estimated, revealing that oil and gas production is contributing far more to warming the planet than previously thought. All told, the scientists say their findings show that oil and gas production account for nearly half of all the methane in our air that is attributable to human activity. “Methane is particularly important as we try to slow the rate of climate change because it’s a strong greenhouse gas over a short time period,” said Denise Mauzerall, an environmental engineering professor at Princeton University, who has studied methane leakage from abandoned oil and gas wells as well as offshore rigs. And while burning natural gas produces far less carbon dioxide than coal-fired power generation, the methane emissions associated with natural gas production are a serious problem for the planet.
