Atmospheric CO2 Level Constant Over the Past 160 Years?

As with astronomy, where Ptolemy was not right because his math “worked” (mostly) and was fancy, but where Copernicus, Galileo and Newton were right because they derived their conclusions  from the facts, so also, climate science must bow to facts and evidence, not vice versa. There will be not knowledge proper in climate science until it is made scientific, i.e., until scientists and “scientists” eliminate all hypotheses, concepts, conclusions, principles and theories in their thinking that are not based on and derived inductively from facts. There are constant reports about the invalidity of the methods and thinking of those who proclaim and push “man made global warming.” For example, ScienceDaily.com reports:

Many climate models also assume that the airborne fraction will increase. Because understanding of the airborne fraction of carbon dioxide is important for predicting future climate change, it is essential to have accurate knowledge of whether that fraction is changing or will change as emissions increase. To assess whether the airborne fraction is indeed increasing, Wolfgang Knorr of the Department of Earth Sciences at the University of Bristol reanalyzed available atmospheric carbon dioxide and emissions data since 1850 and considers the uncertainties in the data. In contradiction to some recent studies, he finds that the airborne fraction of carbon dioxide has not increased either during the past 150 years or during the most recent five decades.

I don’t know about the validity of the research and reasoning; I’ll have to find out more. Recent research, e.g.,”Lindzen on Negative Climate Feedback” (be sure to also read the comments), regarding climate concludes that there is net negative feedback in our climate system, not, as presupposed by climate models that say ‘the earth is in crisis,’ a net positive feedback. Facts must come first in science. Otherwise, our thinking is detached from reality, and our action will follow suit. Then we will be doing things like bleeding or putting leeches on people to make people healthier; or, like kingdoms of old, beating people like to make them be good; or, like some today, recommending people wear running shoes (which end up giving people back and chiropractic problems; see, for example, “Shoes, Sitting, and Lower Body Dysfunctions,”  “Running shoes may cause damage to knees, hips and ankles,” “The Effect of Running Shoes on Lower Extremity Joint Torques“); and more.
