WebNov 26, 2024 · Methane (CH 4) is a colourless, odourless, tasteless, non-toxic gas with the chemical composition of one carbon and four hydrogen atoms. It is a major component of natural gas. CH 4 is highly flammable at very high concentrations of about 50,000 ppm. Methane acts as an asphyxiant at extremely high concentrations. WebMethane has important implications for climate change, particularly in the near term. Two key characteristics determine the impact of different greenhouse gases on the climate: the length of time they remain in the atmosphere and their ability to absorb energy. Methane has a much shorter atmospheric lifetime than CO 2 (around 12 years compared ...
