Global Greenhouse Gas concentrations hit record high, again

Record levels of heat-trapping gases represent further temperature rise.

The emissions of heat-trapping greenhouse gases in the atmosphere once again reached a new record last year and there is no end in sight to the rising trend, reports World Meteorological Organization (WMO).

The new report says that the global averaged concentrations of carbon dioxide (CO2), the most significant heat reflecting gas, in 2022 were a full 50% above the pre-industrial era for the first time. The emissions continued to increase in current year.

a comparable concentration of CO2 was 3-5 million years ago, when the temperature was 2-3°C warmer and sea level was 10-20 meters higher than now.

“There is no magic wand to pass the excess carbon dioxide from the atmosphere. But we have the tools to strengthen our understanding of the drivers of climate change through WMO’s new Global Greenhouse Gas Watch. This will greatly improve sustained observations and monitoring to support more ambitious climate goals,” said Prof. Taalas.
