However, as countries have begun to open back up, pollution levels have rebounded to pre-pandemic levels. Scientists at NASA noticed NO2 bouncing back to near normal levels in China three months after the country shut down transportation and much of its economy in early February 2020. Such a focus on outdoor air pollution has diverted attention away fr…
