Mere months after atmospheric carbon dioxide permanently surpassed a symbolic threshold of 400 parts per million, scientists have more bad news: emissions of methane, a more potent greenhouse gas, have skyrocketed in the past 20 years—and show no sign of slowing.
That’s according to a new analysis published Monday in the journal Environmental Research Letters.
The report, The Growing Role of Methane in Anthropogenic Climate Change, finds that “methane concentrations in the air began to surge around 2007 and grew precipitously in 2014 and 2015,” observes Phys.org.
