🧵There is something the AEI's climate action delayer Roger Pielke Jr doesn't want you to know: Climate related damage as a % of wealth covers population change, GDP & Inflation. The US Bureau of Economic Analysis is the closest thing to “total wealth that can be damaged.” but...

🧵Hi lovely followers, I'm going to concentrate on making short videos from now on, my time spent replying to low follower trolls is better spent educating the public and immunising them against disinfo from the professonal climate deniers. Some of my film work is in this thread

Are you sure? Does climate science believe that CO2 causes rising global temperatures? If yes, we move towards the scientific method and ask two questions: 1. Do you have observations that show the global temperature reacting to CO2 in the atmosphere. (they don't which should end our conversation) 2. If, and the science tells us this, the CO2 causes temperatures to rise, that causes more CO2 as the oceans de-gas, then more heat - a deadly embrace CO2 causes warmth causes more CO2 causes more warmth causes more CO2... you'll be getting it by now. How is this stopped in your science? In my scientific observations there is no relationship between CO2 levels and the global temperature. The Eemian was warmer than the Holocene by about 1-2C, but had a presence of CO2 in the atmosphere of 280 ppm. (Orbital changes are said to make it different but it's merely handwaving and introduces a lot of questions that can't be answered). During the Holocene we've had at least three cooling periods each followed by a warm period with CO2 steady at 280 ppm. Our last cold period finishing around 1850, and, of course followed by warming, as you'd expect at the end of a cold period. Between around 1760 and 1850 the Industrial Revolution took hold, but the temperature didn't increase dramatically, and seem to have taken off in the back end of the 19th Century. I'm having difficulty separating natural changes in temperature increases we'd expect at the beginning of a natural warm period. And, of course through all of this the CO2 in the atmosphere from 1600 to BCE was 280ppm. My own observations lead me to agree with this paper. “The major problem in accepting this theory is has been the lack of observed warming coincident with the historic CO2 increase. In fact, the temperature in the Northern Hemisphere decreased by 0.5C between 1940 and 1970”. J. Hansen, D. Johnson, A. Lacis, S. Lebedeff, P. Lee, G. Rind, D. Russell. Climate Impact of Increasing Atmospheric Carbon Dioxide, Science, Vol 213, 28th August 1981 Minoan Warm Period (approx. 1600–1000 BCE): CO2 280ppm Iron Age Cold Epoch (approx. 1200 – 500 BCE): CO2 280ppm Roman Warm Period (approx. 250 BCE – 400 CE): CO2 275ppm Dark Ages (approx. 500–1000 CE): CO2 280ppm Medieval Warm Period (approx. 800–1300 CE): CO2 280ppm The Little Ice Age Period (approx. 1300 – 1850 CE): CO2 275-280ppm I'm not seeing CO2 as driving temperature in these observations
