Scientist reacts to YouTube climate change comments #2
What emits more CO2 - volcanoes or humans? Find out (and get 20% off) at https://brilliant.org/simonclarkIn 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/Nb84nmXNBqgNotes:(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(5) https://www.researchgate.net/publication/337753937_Evaluating_the_Performance_of_Past_Climate_Model_Projections(6) https://climate.nasa.gov/news/2943/study-confirms-climate-models-are-getting-future-warming-projections-right/(7) https://link.springer.com/article/10.1007/s00382-016-3326-x(8) https://www.climate-lab-book.ac.uk/comparing-cmip5-observations/(9) http://www.ccrc.unsw.edu.au/sites/default/files/Copenhagen_Diagnosis_FIGURES.pdf(10) If you would prefer a written version of this argument then see https://www.skepticalscience.com/saturated-co2-effect.htmAs 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 smdhYou can support the channel by donating at http://www.patreon.com/simonoxfphys Check out my website! https://www.simonoxfphys.com/ ---------- II ---------- My twitter - http://www.twitter.com/simonoxfphys
