First direct observations of methane's increasing greenhouse effect at the Earth's surface

First direct observations of methane's increasing greenhouse effect at the Earth's surface Scientists have directly measured the increasing greenhouse effect of methane at the Earth's surface for the first time. A research team has tracked a rise in the warming effect of methane - one of the most important greenhouse gases for the Earth's atmosphere - over a 10-year period. https://ift.tt/eA8V8J
