  1. Methane

    Methane is a chemical compound with the chemical formula CH 4. It is the simplest alkane and the main component of natural gas. The relative abundance of methane makes it an attractive fuel. However, because it is a gas at normal conditions, methane is difficult to transport from its source. Methane is a potent greenhouse gas, more potent than carbon dioxide unit per unit. The concentration of methane in the Earth's atmosphere in 1998, expressed as a mole fraction, was 1745 nmol/mol, up from 700 nmol/mol in 1750. By 2008, however, global methane levels, which had stayed mostly flat since 1998, had risen to 1800 nmol/mol.

U.S. National Library of Medicine
