for - aerosols - cooling emissions included

comment - complexity of aeresols - aerosols are a good example of the complexity of progress - aeresols are a byproduct of useful human processes such as: - refrigeration - transportation - especially shipping - Waste-to-Energy burning - biomass burning - industrial processes - the aeresols are considered pollution that are the cause of millions of deaths worldwide - this has given motivation to laws that significantly reduce aeresols, as in new shipping fuel convention - at the same time, aeresols have had a cooling effect on global warming, so - it can be considered to be a harmful pollutant with beneficial unintended consequence of lowering global mean temperature
