Mauna Loa CO2
The Mauna Loa CO2 record seems to be the one most referred to by Warmists so I have for some time been greatly amused by what it shows for 2015, that "record" year for warming, according to Warmists. It is so amusing that I think there is a fair chance that it will be "adjusted" -- as the temperature record often has been. So I have decided to take a screen capture of it while it is in its original state. See below.
The 4th column is the actual average CO2 level in ppm. As you can see, the actual CO2 levels just bobbed up and down around 400ppm, showing that CO2 levels plateaued during that year. There was no overall change. There were slight increases but also slight decreases.
So it is perfectly clear that this "warmest" year was NOT caused by anthropogenic CO2 emissions rising -- because total CO2 levels did not rise. ALL the warming was due to natural factors, principally El Nino.
Instead of crowing that it proved their theory, Warmists should be in deep despond that this "warmest" year was TOTALLY natural. CO2 levels did nothing. Once again, there was no linkage between temperature and CO2 levels. The facts are totally at odds with Warmism.
