One molecule of methane is twenty times more efficient at absorbing infrared radiation than a molecule of carbon dioxide (CO 2). The amount of methane is increasing about 1 % a year, faster than any other greenhouse gas. Recently, the concentration is 1. 7 parts per million (ppm), which is nearly twice of what it was a few hundred of ...
