The charge here is that aerosols do not have as great a COOLING effect as previously held and thus an increase in aerosol cooling cannot have a role or as large a role in creating the current hiatus in surface warming.
Unfortunately for you and Fox and WUWT and Breitbard, aerosols are not the current theorized cause of the hiatus in surface warming.
incorrect. the point here is that CGMs use various values for aerosols, all of which cause more offset cooling than this new paper suggests. as always, if you change one side of the equilibrium then the other side is also affected. less aerosol cooling means less CO2 warming.
