I have shown before how the Anthropogenic Global Warming (AGW) cult has a very inconvenient problem in that the atmospheric CO2 concentrations do not correlate well with global temperature anomalies (especially over the past 17 years). To further drive that point home, allow me show you how, over a 52 year period, a seemingly insignificant statistic has a better correlation with global temperature anomalies than atmospheric CO2 concentrations.
Believe it or not, the annual attendance totals for all Major League Baseball (MLB) parks has a very strong correlation with the global temperature anomalies as measured by the Climate Research Unit (CRU).
MLB park attendance has a coefficient of correlation (R2) with global temperature anomalies of 77.8%. For those not statistically inclined, the closer R2 is to 100% means you have a higher degree of certainty making the claim that a proportional change in variable X will cause an equally proportional change in output Y.
As a comparison, here is a graph showing the correlation between atmospheric CO2 concentrations (obtained here) and global temperature anomalies.
You’ll even notice that MLB park attendance ‘explains’ the last 17 years of flat global temperature anomalies which is something the AGW cult can’t do with atmospheric CO2 concentrations. From 1960 to 1997 MLB attendance increased in proportion to global temperature anomalies but then they both leveled off during the past 17 years.
Global temperature anomalies have been flat for the past 17 years while atmospheric CO2 continues its steady increase and this is shown by the lack of correlation in the following graph.
On the other hand, if Major League Baseball refuses to reduce the amount of time it takes to play a 9 inning game and continues to ignore their substance abuse issues, then the AGW cult will have nothing to worry about because the Earth will enter a new ice age as MLB park attendance approaches zero.
