Several Nobel Prize winners have stated that they believe CO2 is the control knob for Earth’s temperature.
This is an amazing theory, given that the historical record shows that the Earth makes sharp swings in temperature, while CO2 continues to trend in the opposite direction.
110,000 years ago CO2 (red) was rapidly dropping while temperature (blue) was sharply rising. This went on for thousands of years. Only a complete flaming moron could believe that CO2 is the control knob. Temperature changes first, and then CO2 follows much later. Ice cores show that temperature is the control knob for CO2, not the other way around.
So the answer is – yes, Nobel Prize winners can be complete morons.
