Methane and ozone
WebGeneva/New York, 26 October (WMO) - In yet another ominous climate change warning, atmospheric levels of the three main greenhouse gases - carbon dioxide, methane and nitrous oxide all reached new record highs in 2024, according to a new report from the World Meteorological Organization (WMO). WebOnce methane and the molecules that create ozone are released into the air by both natural and human-induced sources, these gases mix and react together, which transforms their compositions. When gases are altered, their contribution to the greenhouse warming effect also shifts. So, the true effect of a single GHG emission on climate becomes ...

WebAs part of the carbon cycle, methane and other small hydrocarbons are converted to water and HOx (OH and HO2), species that affect stratospheric ozone concentrations. While a full discussion of the carbon cycle is well beyond the scope of this chapter, we will focus here on just one part of that cycle, the production of methane (CH 4 ) and its oxidation. WebCombusted Methane Gas Increases Risk of Ozone-Related Illness Nitrogen dioxide is also a precursor to ozone, which is created by chemical reactions between volatile organic compounds and oxides of nitrogen in the presence of sunlight. Ozone reacts with and damages organic matter such as plant foliage, the human airway and other lung tissues.
