I looked at the Intergovernmental Panel on Climate Change (UN) global temperature data for the past 140 years, a period during which actual thermometer measurements have been made.
The data suggests that most scientists can't read data.
From 1905 to 1945 the average global temperature increased at .008 degrees C per year. Looked at from the single extreme year 1904 to extreme year 1947 the rate was .02 degrees C per year.
This period, roughly 40 years, was during an insignificant time of global industrial output.
When temperature began to rise again, the average from 1966 to 1997 was .02 degrees C per year. Again looked at from the single extreme year 1963 to extreme year 1997 the rate was .03 degrees C per year.
So we have three periods: roughly 40 years of trivial industrial growth followed by roughly 20 years with a significant burst of industrial output and then 20 years of very high global industrial growth.
This first and last periods have global temperature going up at very similar rates, while in the interim period global temperatures went down. Nothing in this picture shows a connection between industrial activity and global temperature. Nothing.
