Carbon dioxide concentrations reached a new record high in 2020, with comparable levels not seen for roughly 3 million years, the United Nations weather agency said Monday. The findings came in the latest edition of the World Meteorological Organization’s Greenhouse Gas Bulletin. CO2 reached 413.2 parts per million (ppm) in 2020–149% of the pre-industrial level. The increase from 2019 levels came despite pandemic-triggered lockdowns triggering an approximately 5.6% drop in fossil fuel CO2. Methane stood at 262% and nitrous oxide at 123% of pre-industrial levels, the report said. The amount of CO2 in the atmosphere breached the milestone of 400 parts per million in 2015. And just five years later, it exceeded 413 ppm.
Greenhouse gas levels are at new records. Again
Concentration of CO2 in 2020 was 149% of pre-industrial times
Economic slowdown from COVID-19 had no real impact
We are set for a 🌡️ increase much higher than #ParisAgreement target of 1.5°C-2°C.https://t.co/LQ5sVilzcE#COP26 pic.twitter.com/S0NHxa5jg9— World Meteorological Organization (@WMO) October 25, 2021
