Vast Underestimation of Fossil Fuel Contribution to Methane Emissions

Vast Underestimation of Fossil Fuel Contribution to Methane Emissions

Rochester researchers in Greenland drill for ice cores, which contain air bubbles with small quantities of ancient air trapped inside. By measuring the carbon-14 isotope in air from more than 200 years ago, the researchers found that scientists have been vastly overestimating the amount of fossil methane emitted by natural sources, and have therefore been underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.
