He has a point. Scientists always think they know something, once upon a time the scientific community thought the Earth was flat and that the Sun revolved around the Earth, they were wrong. Modern Science is not incontrovertible. While the climate definitely is changing, there is no way to know for certain that it's human caused rather than the natural climate changes this planet has always had.

Our understanding of chemistry is sufficient to make the statement that increased atmospheric CO2 increases temperature in the long term absolutely trivial. Science has determined a round earth for several thousand years niw, by the way. The example is bad, because a flat earth is not a scientific conclusion, but an assumption that was made in the lack of sufficient information to make a theory.
