Todays lecture: introduction to air pollution + atmospheric science with respect to air. >this was caused by a temperature inversion that trapped the smoke + fog. > caused respiratory problems and slowly suffocated thousands. Beijing"s first red smog alert (dec 2015) Ttc air quality like beijing (april 2016) >more people have died from poor air quality/pollution than malaria and hiv/aids combined.
