  • Description:
    Despite economic disruptions due to the global COVID-19 pandemic during most of 2020 that resulted in an estimated 6%–7% reduction in human-caused carbon dioxide (CO2) emissions into Earth’s atmosphere, this was not enough to slow the accumulation of concentration levels. All major greenhouse gases, including CO2, reached new record high concen- trations for the year. The annual global average carbon dioxide concen- tration at Earth’s surface was 412.5 ± 0.1 ppm, 2.5 ± 0.1 ppm more than in 2019, and the highest in at least the past 800,000 years. The year-over- year increase in the global CO2 levels has tripled over the past half centu- ry, from an average of 0.8 ± 0.3 ppm yr–1 in the 1960s to 2.4 ± 0.4 ppm yr–1 in the 2010s.
