Image if all the time and effort the denialists spent pretending to be climate experts was spent on - ANYTHING - else? The pyramids of Egypt could have been rebuilt a dozen times over by now.
I can certainly imagine how climate science would look different if the focus was on solar influence rather than.the cul-de-sac of CO2. Ice had been melting since the 1800a, what is the neutral point of TSI where there is no warming or cooling? That is apretty important piece of info.
