“Methane levels have been spiking considerably in recent years, according to an editorial published in the journal Environmental Research Letters.
Methane, a major greenhouse gas, is not as talked about as much as a more abundant contributor to climate change, carbon dioxide. But while concentrations of methane in the atmosphere are not nearly as high as CO2, methane has a much higher heat-trapping potential.
Over the past few years, CO2 emissions have flattened out, in a piece of rare good news for those concerned about the global climate. But according to the editorial, methane levels in the atmosphere have risen since 2007 and spiked over the past two years, throwing another wrench in the works of efforts to rein in rising temperatures.”
