Scientists at the University of California-Santa Cruz have found evidence that large methane reservoirs exist beneath the Antarctic ice sheet. According to a university report, the Antarctic Ice Sheet is likely a major a source of methane, a powerful greenhouse gas. Greenhouse gases absorb infrared radiation and keep the heat in the atmosphere.
Scientists believe that micro-organisms existing under oxygen-deprived conditions converted old organic matter beneath the Antarctic Ice Sheet to methane. Scientists are concerned that if the ice sheet shrinks, the methane could enter the atmosphere.
