Powerful links between methane and climate change

Using data gathered over the last four decades to study the effects of temperature changes and rain on the atmospheric concentration of methane, scientists have concluded that Earth could be both delivering more, and removing less, methane into the air than previously estimated, with the result that more heat is being trapped in the atmosphere. The study, published in the scientific journal Nature Communications on 23 June, addresses the large uncertainty about the impact of climate change on atmospheric methane. The study finds that this impact could be four times greater than that estimated in the latest Intergovernmental Panel on Climate Change (IPCC) report.
