First, some CORRECTIONS:
1) Jerry Taylor did leave the Cato Institute, and set up his own think-tank called the Niskanen Center. It also reflects Libertarian views.
2) Some reputable researchers have found that if the reduction in forcing due to CFCs (a greenhouse gas that was banned under the Montreal Protocol) is included, Hansen's Scenario B temperature projection is even more accurate, and likely a bigger cause for him being slightly off actual temperature rise than the higher estimate he gave for the Earth's sensitivity. So even leaving Hansen's estimate for sensitivity as it is, a perfect reproduction of actual temperatures may be given given by including actual reduction of CFC emissions. My thanks to subscribers who pointed this out. Gavin Schmidt has written about this on RealClimate (see realclimate.org/index.php/archives/2019/12/how-good-have-climate-models-been-at-truly-predicting-the-future), and co-authored a paper by Zeke Hausfather et al, to be found at: pubs.giss.nasa.gov/docs/tbp/inp_Hausfather_ha08910q.pdf -- or try
agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2019GL085378 if that link doesn't work.
Whatever the reason for the difference, it doesn't change the fact that Hansen's temperature projection was almost spot on.
3) At 18:23 the graph showing Hansen's predictions was compiled by Skeptical Science, using Hansen's 'Earth Iris' feedback prediction.

The charity I strongly endorse is called ASRI. It’s a hospital in Borneo that provides affordable health care to villages on the edge of a national park in return for a pledge not to cut down trees, The pledges are monitored, and the result has been a dramatic decrease in deforestation rates and an increase in the health of the local population. The founders are hoping to spread the idea to other countries. (see psmag.com/social-justice/save-the-trees-well-save-your-life-46121 for an explanation of their work.)
