So, I’m reading WUWT and I see this ……
Problems with Statistical Tests of Pre-1958 Atmospheric CO2 Concentration Data
It’s a fairly technical post, and to be sure, it does illustrate some problems. But, I want to focus on what I believe should be more obvious problems.
To give you some insight to the gravity of this, I’ll quote a paragraph from the post……
Most researchers who have examined pre-1958 relations between GHGs and temperature have used Antarctic ice core data provided by Etheridge et al (1996) (henceforth Etheridge). Etheridge measured the CO2 concentration of air trapped in the ice on Antarctica at the Law Dome, using three cores that varied from 200 to 1200 meters deep.
And, this is true.
But, there’s a problem with this. Well, there’s lots of problems with this. First of all, we have to pretend all of the ice moves uniformly in lock-motion…
