Climate change 'sceptic' Ian Plimer argues CO2 is not causing global warming

[Freedom&Liberty]

Carbon dioxide in the atmosphere is a natural phenomenon caused by volcanoes and is not responsible for climate change, a scientist has claimed.

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."

"If we had only had warming, then there would be a connect between co2 and temperature, there is not," he added.



Prof Plimer has come under attack as a "denialist poster boy" whose theories are in danger of stopping the world from tackling the grave dangers of climate change.
But he said the scientists "frightening people witless by following the party line" are motivated by politics and research funding.


"They are taking advantage of the current situation. That is understandable. In previous times people got wonderful research grants in a war against cancer and they achieved a lot of money for that. Now we have a war on climate change and we have a huge number of people out there who have their career staked on it and are beneficiaries of this process."

More and more climate science skeptics are coming out against consensus.

Plimer was challenged on this point by George Monbiot of The Guardia

10. You state that “Volcanoes produce more CO2 than the world’s cars and industries combined.” (p413)

This is similar to the claim in The Great Global Warming Swindle, whose narrator maintained that “Volcanoes produce more CO2 each year than all the factories and cars and planes and other sources of man-made carbon dioxide put together.”

But you do not provide a source for it.

This is what the US Geological Survey says: “Human activities release more than 130 times the amount of CO2 emitted by volcanoes”.

a. Please provide a reference for your claim.

http://www.monbiot.com/archives/2009...th-ian-plimer/

as you can see he failed to answer these questions, instead posted things of his own. he was requested to answer, failed, so with plenty of warning from mr. monbiot, his failure meant a cancellation of the planned debate

why is he so afraid of debating George Monbiot if his arguments are sound?

Not in in that link it doesn't.


Apparently, he considers himself a reference.

10. From atmospheric CO2 measurements, stable isotopes, radiogenic Kr and hemispheric transport of volcanic aerosols, calculate the rate of mixing of CO2 between the hemispheres of planet Earth and reconcile this mixing with CO2 solubility, CO2 chemical kinetic data, CO2 stable and cosmogenic isotopes, the natural sequestration rates of CO2 from the atmosphere into plankton, oceans, carbonate sediments and cements, hydrothermal alteration, soils, bacteria and plants for each continent and ocean. All assumptions must be justified and calculations and sources of information must be shown. Calculations may need to be corrected for differences in 12CO2, 13CO2 and 14CO2 kinetic adsorption and/or molecular variations in oceanic dissolution rates.

could you clarify what you mean in this sentence
it actually does if you go to the 3rd page "effects" (and the fifth is "references) across the top of the article

Comparison of CO2 emissions from volcanoes vs. human activities.
Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1999, 1991). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 27 billion tonnes per year (30 billion tons) [ ( Marland, et al., 2006) - The reference gives the amount of released carbon (C), rather than CO2, through 2003.]. Human activities release more than 130 times the amount of CO2 emitted by volcanoes--the equivalent of more than 8,000 additional volcanoes like Kilauea (Kilauea emits about 3.3 million tonnes/year)! (Gerlach et. al., 2002)

Okay, thanks. You've effectively disputed one point that Pilmer made. Good for you.

not bad for an accountant, who got a D in science in the junior certificate
