MRS Carroll, you would be aware 97 per cent of scientists believe anthropogenic processes are the main reasons why global warming is occurring.
NASA findings bear this out. Its research, along with 97 per cent of scientists, finds that 38million tonnes of carbon dioxide is poured into the atmosphere every year.
Yet Mrs Carroll does not agree with them. She feels 650,000 years is too short a time to arrive at such a conclusion.
Climate-change deniers point to natural causes, volcanoes, solar radiation and inter-glacial periods.
These are all very slow. In the time period since the industrial revolution, temperatures have risen at twice the rate previously.
Mrs Caroll is probably not aware that the "evidence" of climate change is based on the analysis of just two fossils: coccoliths and forifemenifer.
They were contaminated and it was assumed uniformitarianism was not used in the study. I looked at that journal and found no specific reference to climate.
Mrs Carroll's reference, Ian Plimer, is seen as an odd ball in geological research and a good friend of Cory Bernardi.
Make of that what you will.
