The concentration of heat-trapping greenhouse gases in the atmosphere once again hit a new record last year and there appears to be no halt to this escalating trend, according to a new report by the World Meteorological Organisation (WMO).
The global averaged concentrations of carbon dioxide (CO2), considered the most critical greenhouse gas, were a staggering 50 per cent above the pre-industrial era (1850-1900) in 2022 for the first time. These levels have continued to escalate in 2023, it said.
The WMO’s Greenhouse Gas Bulletin noted that although the growth rate in CO2 concentrations was slightly lower than the preceding year and the decade’s average, this decline was likely due to short-term variations in the carbon cycle.
