Methane and other gases

Geographical (Geographical Magazine Ltd.);Dec2007, Vol. 79 Issue 12, p12
This article discusses a report on the contribution of methane, nitrous oxide and other greenhouse gases to global warming. According to the report, these greenhouse gases are more efficient at warming the atmosphere than carbon dioxide, but are present in much smaller quantities, and their overall contribution to global warming is less. The report indicated that methane is about 20 times more effective than carbon dioxide at trapping heat in the atmosphere. Methane is produced by rice cultivation, coal mining, energy production and the rearing of livestock.
