Objection: Scientists claim that Global Warming from GHG's is actually being countered somewhat by Global Dimming from aerosol pollution. They even say that's what caused cooling in mid-century. But, GHG's are evenly mixed around the globe while aerosols by far impact the northern hemisphere where they are produced more than the southern hemisphere. This means that warming should be greater in the southern hemisphere, which is the opposite of what is…
