Now Keppler and his colleagues find that plants, from grasses to trees, may also be sources of the greenhouse gas. This is really surprising, because most scientists assumed that methane production requires an oxygen-free environment. Previously, researchers had thought that it was impossible for ...

The United States Environmental Protection Agency maintains an inventory of greenhouse gas emissions in accordance with the Intergovernmental Panel on Climate Change. Methane (CH 4 ), a potent gas with a global warming potential 86–125× that of carbon dioxide (CO 2 ) over a twenty-year period...
Aquatic ecosystems are globally significant sources of the greenhouse gas methane to the atmosphere. Until recently, methane production was thought to be a strictly anaerobic process confined primarily to anoxic sediments. However, supersaturation of met

请根据短文内容,回答题。Plant GasScientists have been studying natural sources of methane for decades but hadn&39;t regarded plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heidelberg..
The genetic types of water soluble methane gas in Gushi sag in Weihe Basin were studied. Research on carbon isotope δ13C1 and content of heavy hydrocarbon in water soluble gas methane showed that the genetic types of water soluble
These gases are of mixed origin,and the heavy hydrocarbon gases were mainly derived from the secondary cracking of oil augmented with coal-type gas,whereas methane was mainly a coal-type gas. Gas-source correlations indicated that the natural gases reservoired in the second member of the Xujia...
