Climate change ‘sceptic’ Ian Plimer argues CO2 is not causing global warming
November 12, 2009
Professor Ian Plimer, a geologist from Adelaide University, argues that a recent rise in temperature around the world is caused by solar cycles and other “extra terrestrial” forces.
He said carbon dioxide in the atmosphere, widely blamed for global warming, is a natural phenomenon caused by volcanoes erupting.
“We cannot stop carbon emissions because most of them come from volcanoes,” he said. “It is a normal element cycled around in the earth and my science, which is looking back in time, is saying we have had a planet that has been a green, warm wet planet 80 per cent of the time. We have had huge climate change in the past and to think the very slight variations we measure today are the result of our life – we really have to put ice blocks in our drinks.”
Most mainstream scientists agree that the recent warming period was caused by an increase in carbon dioxide since the industrial revolution.
However Prof Plimer said the world has experienced three periods of cooling since 1850 and furthermore carbon dioxide was increasing during many of those cooler periods.
“If we had only had warming, then there would be a connect between co2 and temperature, there is not,” he added.
