Ian Plimer - Climate Change Scepticism

Climate Change Scepticism

Carbon dioxide has an effect on the atmosphere and it has an effect for the first 50 parts per million and once it's done its job then it's finished and you can double it and quadruple it and it has no effect because we've seen that in the geological past, and we've seen it in times gone by when the carbon dioxide content was 100 times the current content. We didn't have runaway global warming, we actually had glaciation, so there's immediately a disconnect. So carbon dioxide is absolutely vital for living on earth; it's plant food, all of life lives off carbon dioxide. To demonise it shows that you don't understand school child science.

Plimer accuses the environmental movement of being irrational, and says that the vast bulk of the scientific community, including most major scientific academies, is prejudiced by the prospect of research funding. He has characterised the Intergovernmental Panel on Climate Change so: "The IPCC process is related to environmental activism, politics and opportunism" and "the IPCC process is unrelated to science". He is critical of greenhouse gas politics and argues that extreme environmental changes are inevitable. Scientists in the field say that his writings misrepresent climate data and display numerous other errors.
