Greenhouse Gas Increase in 2023

Greenhouse gases reached their highest levels in 2023, new research revealed. The WMO only noted an increase of over ten percent within only twenty years. This increase is concerning. They stress the need to do something in order to prevent climate change.

Principal Greenhouse Gas Concentrations and Effects

• Average global concentrations of key greenhouse gases in 2023 were: Concentrations are as follows: CO2: 420 ppm, CH4: 1934 ppb, N2O: 336.9 ppb.
• CO2: Temperature: 1.5 times pre-industrial levels, CO2: 151%, CH4: 265%, N2O: 125%.
• Rising due to huge fires in vegetation, lowered absorption of carbon dioxide in forests, and optimum emissions from human and industrial uses of fossil fuels.
• WMO Secretary General Celeste Saulo stressed the severity of the situation and the rehearsals of decision-makers for the achievement of the Paris Agreement. 
• In 2023, CO2 rise was 2.3 ppm, which was the twelfth straight year of CO2 rise of more than 2 ppm.
• Long-lived greenhouse gas radiative forcing from 1990 to 2023 enhanced by 51.5%, of which CO2 was responsible for 81%.
• The past speaks to what could happen if present trends are not changed.
