Record levels of carbon dioxide and other pollutants detected in 2023, WMO reports
Summary: In 2023, the concentration of carbon dioxide in the atmosphere reached a record high of 420 parts per million, according to the World Meteorological Organization (WMO). This marks a more than 10% increase over the past two decades.
The rise in carbon dioxide is attributed to ongoing fossil fuel use, major wildfires, and reduced carbon absorption by trees. Methane and nitrous oxide levels also surged, with methane reaching 1,934 parts per billion, a 265% increase from preindustrial levels.
The WMO's findings highlight a significant gap in efforts to meet climate goals set by the Paris Agreement. Current trends indicate that global warming could exceed targets, with scientists estimating that substantial investments are needed to reduce emissions effectively.
