The short version of the climate hysterics’ fossil fuel causes global warming farce is that use of fossil fuels releases CO2 into the atmosphere, that CO2 traps more heat and global temperatures rise. The ratio of how much temperature supposedly rises for each additional amount of CO2 in the atmosphere is referred to as the climate sensitivity to CO2. The climate hysterics use models, of course, to claim a very high sensitivity rate. The reason the models are so bad at predicting temperature is because the sensitivity is way too high. A new paper purports to assess CO2 sensitivity thoroughly. (JOC Article)
The paper is technical and you have to pay for it, but there is a great discussion at this website run by a climate realist. (NTZ Post) (The hysterics like to call them deniers, but since this group of scientists who aren’t ideologues actually believe in data and research, I prefer to call them realists.) As the post explains, this paper finds a sensitivity 40% lower than that used as the consensus figure by the hysterics. This means temperatures will rise far less than the hysterics wildly exclaim. Water vapor is also found not to be a postiive feedback for increasing CO2 levels, but to have a dampening or negative feedback. The paper’s findings also suggests that most of the warming in the past 150 years has been driven by natural processes. And the authors find that in some parts of the world, i.e. Antarctica, more CO2 actually means lower temperature. Guess all that ice won’t be melting after all.
