Wherever they come from, the reports seem to follow each other and resemble each other. Those published by the World Meteorological Organization (WMO) are no exception. This suggests that greenhouse gas concentrations in Earth’s atmosphere are set to reach a new record in 2022.

Greenhouse gas concentrations in our atmosphere have never been as high as they will be by 2022. This is the sad conclusion of the World Meteorological Organization (WMO). But how is this possible? Very simply because our shows go on. At a pace that is too slow to make a real difference. Greenhouse gases are accumulating in our atmosphere, causing a continuous increase in temperature.

More and more CO2 in the atmosphere

The latest WMO report provides some details. In 2022, the global average concentration of carbon dioxide (CO)2) reached a record high of 417.9 parts per million (ppm). This is, for the first time, 50% higher than pre-industrial values. As a reminder, CO2 It is the most important greenhouse gas present in our atmosphere. It comes mainly from the combustion of fossil resources.

Experts point out that if the increase since 2021 is slightly lower than the average increase over the past 10 years, this is undoubtedly due to the increased absorption by vegetation and the ocean made possible by the La Nina phenomenon. The presence of an El Nino episode could change things…

Other greenhouse gases also follow the same path

CO concentration2 Unfortunately it is not the only one to increase. The second greenhouse gas that contributes most to global warming is methane (CH4) – 60% of human origin (breeding ruminants, exploitation of fossil fuels, etc.) – follows the same path. Today it is 264% of the pre-industrial era!

Nitrous oxide levels (N2o) – 40% of human origin (combustion of biomass, fertilizers, industry, etc.) –, the third most important greenhouse gas, has experienced unprecedented growth between 2021 and 2022.

Statistics to consider just days before the opening of COP28.
