Accepting Quote by Vaclav Klaus
“To reduce the interpretation of the causality of all kinds of climate changes and of global warming to one variable, CO2, or to a small proportion of one variable - human-induced CO2 - is impossible to accept. Elementary rationality and my decades-long experience with econometric modelling and statistical testing of scientific hypotheses tell me that it is impossible to make strong conclusions based on mere correlation of two (or more) time series.”
About This Quote
Source Speech: Public address on climate policy, Czech Republic, 2010
The claim that CO2 alone explains all climate change is oversimplified; correlation does not prove causation, and robust conclusions need rigorous statistical testing.
In simple terms: CO2 alone cannot explain climate change; correlation isn’t causation.
