Washington Post: CO2 levels hit highest point yet, even after 15-month idling of transportation, industry and overall carbon emissions.
Initial air pollution reductions during the Covid-19 pandemic had an immediate measurable impact on global and local air quality. Demand for oil dropped by nearly 9 percent. That didn't stop the atmospheric carbon dioxide level from reaching its highest concentration since records began.
It's a sign of how difficult it will be to curb overall global emissions enough to prevent the worst consequences of climate change and global warming.
"Even as international borders closed and global economic activity took a massive hit throughout much of 2020, researchers have found that human-caused emissions rebounded fairly quickly after decreasing sharply early in the pandemic," the Washington Post reported.
