Greenhouse Gas Concentrations : United Nations Issued Warning
The United Nations issued a warning highlighting the unprecedented surge in greenhouse gas concentrations in the atmosphere, setting new records in 2022.
- UN’s World Meteorological Organization (WMO)’s 19th Annual Greenhouse Gas Bulletin outlines the concerning implications, foreseeing heightened temperatures, intensified extreme weather events, and elevated sea levels as a consequence.
- WMO in its 19th annual Greenhouse Gas Bulletin stated that levels of the three main greenhouse gases: carbon dioxide, methane, and nitrous oxide, all surpassed previous records, marking an escalation in their atmospheric presence.
- In 2022, carbon dioxide concentrations reached 418 parts per million, methane at 1,923 parts per billion, and nitrous oxide at 336 parts per billion, significantly surpassing pre-industrial levels by 150%, 264%, and 124%, respectively.
- Of the three major greenhouse gases, carbon dioxide (CO2) accounts for about 64% of the warming effect on the climate.
- Methane ranks as the second-largest contributor to climate change, causing about 16% of warming.
- Nitrous oxide contributes around 7% to the warming effect.
