(PhysOrg.com) -- Buried below the tundra of China’s Qinghai-Tibet Plateau is a type of frozen natural gas containing methane and ice crystals that could supply energy to China for 90 years. China discovered the large reserve ...
(PhysOrg.com) -- Scientists worry that rising global temperatures accompanied by melting permafrost in arctic regions will initiate the release of underground methane into the atmosphere. Once released, that methane gas would ...
