WebMethane has a much shorter atmospheric lifetime than carbon dioxide (CO 2) – around 12 years compared with centuries – but absorbs much more energy while it exists in the atmosphere. Methane also affects air quality because it can lead to ground level (tropospheric) ozone, a dangerous air pollutant. Methane leaks can also pose explosion … As of 2001, the mean lifespan of methane in the atmosphere was estimated at 9.6 years. However, increasing emissions of methane over time reduced the concentration of the hydroxyl radical in the atmosphere. Pogledajte više Atmospheric methane is the methane present in Earth's atmosphere. The concentration of atmospheric methane—one of the most potent greenhouse gases —is increasing due to methane emissions Pogledajte više The amount of methane in the atmosphere is the result of a balance between the production of methane on the Earth's surface—its source—and the destruction or removal of methane, mainly in the atmosphere—its sink— in an atmospheric chemical Pogledajte više The AR6 of the IPCC said, "It is unequivocal that the increases in atmospheric carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) since the pre-industrial period are overwhelmingly caused by human activities."
