Not sure this belongs here but wanted to start a discussion to hear thoughts on something. Let's say this shutdown/quarantine whatever you want to call it continues for another 4-6 months (hopefully not). We have seen factories closing, people not travelling, air traffic limited, etc. I have seen pics of cities before and current that show visible reduction in smog/haze/pollutants/emissions. I dont have actual proof that the reduction in emissions is doing anything, thus why I wanted to start a discussion to see if these cutbacks are actually helping to clean the atmosphere at all AND what could the implications be short term and longer term irt the weather?
