Skeptical Australian Radio commentator slammed over climate change remarks on TV science panel

That weed Karoly has been a Warmist from wayback.  He is far from an unbiased scientist.  Note that all he points to is raised levels of CO2.  But nobody disputes that.  What about the global temperature? Is that rising? Crickets. (It's falling). Typical Greenie deviousness

His argument that Australia is contributing more than its "fair share" of global warming is also  faulty.  What he is referring to is again CO2 emissions. And skeptics see CO2 as being primarily plant food  -- which it undoubtedly is -- and not as any significant influence on global temperature.  There have been long periods when CO2 has shot up while temperatuers remained stable -- the 30 relatively recent years of 1945 to 1975, for instance. Karoly has his head in an unmentionable place

Alan Jones copped an absolute roasting on tonight’s episode of Q&A — despite not even being on the panel.

The radio shock jock was slammed by a panel of science experts for downplaying human impact on climate change, after he said we only contribute three per cent to greenhouse gas emissions during his own Q&A appearance last month.

“I saw the radio commentator Alan Jones on TV recently, and he said that 0.04 per cent of the world’s atmosphere is CO2,” the questioner said. “‘Three per cent of that human beings create around the world, and of that, 1.3 per cent is created by Australians’. Is that correct, and if so, is human activity really making a difference?”

Professor David Karoly, an Australian atmospheric scientist based at CSIRO, bluntly responded: “Not everything Jones says is factually accurate.”

Prof Karoly said that, while it’s correct that 0.04 per cent of the world’s atmosphere is carbon dioxide, Jones’ statistics around humans causing climate change — and the role Australians specifically play — is completely false.

“I am a climate scientist, and Alan Jones is wrong. The reason he’s wrong is because we know that yes, the greenhouse gas concentration in the atmosphere is 400 parts per million … and that corresponds to about 0.04 per cent.

“All his other numbers were wrong. We know that carbon dioxide concentration 100 years ago was about 280 parts per million, or 0.028 per cent, but it’s grown 120 parts per million — or about 40 per cent — and that 40 per cent increase is due to human activity. We know that for absolute certain.” [Real scientists never know anything for absolute certain]

In other words, Prof Karoly was saying we’ve technically increased greenhouse gases by 40 per cent, not the three per cent figure Jones used.

The scientist also slammed the radio host for implying that Australians contribute a negligible amount to global warming.

“Australians have contributed about 1.5 per cent. Now that sounds like a small amount, but Australia only makes up 0.3 per cent of the population, and we’re contributing 1.5 per cent roughly of greenhouse gases,” said Prof Karoly. “So is it fair that 0.3 per cent of the global population has contributed 1.5 per cent? We’ve contributed much more than our fair share.”

Particle physicist Brian Cox said people think the climate is overly “simple”, which is a big part of the problem. “But actually, the climate is extremely complicated. These models are very, very complicated and constantly evolving.

“I think many people assume you can just work out what the climate’s going to do, like it’s common sense. But it’s actually a very complex system.” [Too complex to support any firm prediction, in fact]
