In this video I read through and react to comments on my YouTube videos about climate change. There's some interesting stuff...
Previous climate comments video: https://youtu.be/Nb84nmXNBqg
Notes:
(1) From the excellent Carbon Brief, with a more detailed breakdown https://www.carbonbrief.org/analysis-why-scientists-think-100-of-global-warming-is-due-to-humans
(2) Note that the timeseries here are artificially (stochastically) generated - this is just a figure to demonstrate the point!
(3) Actually the uncertainty is a lot larger, from 72% to 146%, with an average of about 110%! https://www.carbonbrief.org/analysis-why-scientists-think-100-of-global-warming-is-due-to-humans
(4) Data here is from ERA-Interim, 2m temperature, 3 degree grid, just south of London

As in the previous video, I use my training as a scientist and researcher in atmospheric physics to discuss and dissect YouTube climate change comments. Here we discuss CO2 saturation, how accurate climate models are, why scientists (don't actually) overestimate global warming, and Elon Musk for some reason I don't know smdh
