WMO Bulletin: Never was there more CO2 in the atmosphere

Shortly before the World Climate Conference in Glasgow, the annual greenhouse gas bulletin of the World Meteorological Organization (WMO) was published.

According to the bulletin, CO2 concentrations continued to rise – despite reduced economic activity due to the COVID-19 pandemic – and reached a dramatic record level in 2020. Moreover, the increase in 2020 was greater than the average from 2011 to 2020.

The new maximum level of the greenhouse gas CO2 in 2020 was 413.2 ppm (particles per million particles). In 2019, it was 410.7 ppm.

Unless much tougher climate action than today is implemented, the world would not meet the Paris climate agreement targets to limit warming to 1.5 to 2 degrees, WMO chief Petteri Taalas said.
