John Cook claims that there is a 40 Year Delay Between Cause and Effect when it comes to CO2
Let’s put that theory to the test.
The peer reviewed hockey stick shows temperatures suddenly blasting upwards around the turn of the century. Using the Cook 40 year rule, that would imply a response to changes in CO2 from the middle of the 19th century. Only problem is, there weren’t any significant changes in CO2 around that time. Atmospheric CO2 was nearly dead flat.
So what is it John. Is the hockey stick wrong? Are you wrong? Or both?
