A positive side effect from the coronavirus pandemic has been plunging pollution levels across the planet.
CO2 emissions have decreased significantly, with a new report from Carbon Brief projecting that 2020 could see the largest yearly global decline ever.
According to researchers at IQAir, 7 of the 10 major cities they studied saw microscopic particulate matter levels drop substantially.
However, this period of cleaner air might only last a little while longer. IQAir believes air pollution will return once lockdown orders are lifted and economies start back up.
