Methane gas levels begin to increase again
CAMBRIDGE, Mass. The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers.
Methane levels in the atmosphere have more t...
