Historic carbon dioxide levels have been much higher than now 'yet without ice ages'

Geologist Professor Ian Plimer says climate change cannot be “driven by carbon dioxide emissions” and the study claiming 97 per cent of scientists believe humanity is the cause of climate change is mainly touted by activists over scientists. “We happen to be a planet that is in the goldilocks zone and that is where we don’t boil off our oceans and we don’t freeze our oceans, on our planet we have solid, liquid, and vapour water and it is that water vapour in the atmosphere that drives changes in the climate,” he told Sky News host Cory Bernardi. Professor Plimer said this process had always been happening and climate change happens for many reasons but there “cannot be climate change driven by carbon dioxide emissions”. “Climate is always changing for a great diversity of reasons for pretty well the whole history of planet earth we have had carbon dioxide contents in the atmosphere much higher than now yet without ice ages.”
