Covid pandemic has little impact on rise in CO2...Despite pandemic shutdowns, carbon dioxide and methane surged in 2020...Study explains surprise surge in methane during pandemic lockdown...Travel drop aided lockdown methane surge, study finds

"The global response to the Covid-19 crisis has had little impact on the continued rise in atmospheric concentrations of CO2, says the World Meteorological Organization (WMO)."

"Carbon dioxide levels are now higher than at anytime in the past 3.6 million years
Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today.

The global surface average for carbon dioxide (CO2), calculated from measurements collected at NOAA’s remote sampling locations, was 412.5 parts per million (ppm) in 2020, rising by 2.6 ppm during the year."

"A mysterious surge in planet-heating atmospheric methane in 2020 despite COVID lockdowns that reduced many human-caused sources can be explained by a greater release from nature and, surprisingly, reduced air pollution, scientists said Wednesday.

Methane stays in the atmosphere only a fraction as long as carbon dioxide, but is far more efficient at trapping heat and is responsible for roughly 30 percent of the global rise in temperatures to date.

Released from the oil and gas, waste and agriculture sectors, as well as through biological processes in wetlands, the powerful greenhouse gas is a key target for efforts to curb global warming."
