Does human emission of CO2 cause global warming?
This is a scientific question and can be answered using the scientific method with observed global mean temperature data. A graph of global mean temperature from the Climate Research Unit of the University of East Anglia is shown in the above graph [1]. The first period is from 1910 to 1940 & the second period is 60-years latter from 1970 to 2000. After human emission of CO2 for 60-years, the rate of change of global mean temperature of 0.15 deg C per decade from 1970 to 2000 is nearly identical to that of 0.16 deg C per decade from 1910 to 1940. That is, after a 5-times increase in human emission of CO2, there was no increase in the rate of increase of global mean temperature. This data contradicts the theory that human emission of CO2 causes global warming.
