WMO says greenhouse gas levels surged to new record in 2023
A report by the World Meteorological Organization reveals global greenhouse gas levels surged to a new record last year, locking the planet into a path of rising temperatures for years ahead.
The annual Greenhouse Gas Bulletin by the organization reveals carbon dioxide concentrations have increased 11.4 % in 20 years.
Secretary-General Celeste Saulo says: “We are clearly off track to meet the Paris Agreement goal of limiting global warming to well below 2°C and aiming for 1.5°C above pre-industrial levels.”
Data from the organization’s Global Atmosphere Watch network shows the globally averaged surface concentration of CO2 reached 420 parts per million last year.
Methane and nitrous oxide concentrations also increased sharply.
The report shows the atmospheric CO2 increase for 2023 was 2.3 parts per million, higher than in 2022 but slightly below the previous three years.
This increase marks the 12th consecutive year with CO2 levels rising by more than 2 parts per million annually.
The uptick in CO2 in 2023 is attributed to a mix of persistently high fossil fuel emissions, extensive vegetation fires, and a potential decrease in forest carbon absorption.
