How accurate are scientific predictions about climate?

SOURCES ARE BELOW 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, and Zeke Hausfather is working on a paper showing it. Whatever the reason for the difference, it doesn't change the fact that Hansen's temperature projection was almost spot on. DONATIONS 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 https://psmag.com/social-justice/save-the-trees-well-save-your-life-46121 for an explanation of their work.) You can make a donation through the US fundraising arm called Health in Harmony: https://healthinharmony.org/donate/ Thanks for supporting their good work, and this channel. Even if you hate my channel, please support them anyway. I AM NOW COMPILING THE LIST OF SOURCES.
