Over recent and deep geological time, when temperature and carbon dioxide are correlated, temperature is the ‘control knob’ of CO2, not vice-versa. Otherwise there is almost no correlation

The basic theory underlying orthodox climate science is that the global temperature is highly sensitive to changes in carbon-dioxide levels. This is sometimes called the “control-knob” theory.1 If CO2 increases, so does temperature. If CO2 falls, so does temperature, more or less in lock-step—CO2 is the “control knob” of temperature.
And since we are in a “warming” world, and because CO2 levels are also going up—in other words, because temperature and CO2 levels appear to be correlated—orthodox climate science accepts that they are correlated—in fact, strongly correlated, as we’ll see.… Read more
