: Re sunshades, yes, what LG said at 14, plus, the shades do nothing to reduce the ocean acidification... why would we want to expend the energy and resources to treat a symptom of planetary CO2 poisoning and take all the risks that LG describes when it pretty clear that the best approach is a wildly ambitious conversion to very low emission energy / transportation / agriculture systems **** concurrent with, and achieved by the same means, *** a wildly ambitious global program of CO2 sequestration / removal... and... under *** 300 ppm *** in 20 — 100 years, at most?

I suppose that if all uncertainties are resolved in the direction of lower risk, we just might get away with BAU for the next few decades without a complete disaster (though continued sea level rise, ocean acidification and 2 degrees Celsius actually sound pretty risky to me, and the risk that there are other factors in play seems to be reinforced by paleo data on glacial - interglacial transitions).
