> Where is the actual proof humans are changing the climate? Not theory. Not models. But scientific proof? If we are going to make huge policy shifts that affect everyone’s economic prosperity, then it better be more than some computer modeling. The only way to get actual proof if is we ran a large number of experiments on parallel worlds. This is impossible. There is no control in climatology, only extrapolation. Climatology is more akin to history or archeology than science.
