Which scientist is right and which one is wrong?

Dammed if I know, however I do know that before this climate change debate and the hysteria over greenhouse gases, the earths climate has changed many times before the industrial age.

The Sahara desert was once productive land. Australia was once a lot wetter than it is now, long before white man discovered it.

Ancient civilizations disappeared without trace because of climate change and to my knowledge they were not producing much in the way of carbon dioxide.

Great article! Certainly a lot more truthful than George "just yell louder than anybody else" Monbiot's article. PS Monbiot has just bought his first car (a real clunker too), right when the Earth is in such crisis! lol

I urge everybody to watch the Great Global Warming Swindle documentary to be shown on the ABC 12th July 8:30pm. Look at both sides of the debate and make up your own mind.

The docco was widely discredited long before the ABC tweaked it

Very surprised the ABC is even showing snippets. It is highly unlike them to show the counter view to the socialist left who are using climate change as a political tool. Makes for a good laugh. I am glad that at least some of the many sensible scientist are getting a little airplay. I just wondered what happened to all those scientist who warned of global cooling 30 years ago.

"The docco was widely discredited long before the ABC tweaked it"
Only in warmer's world...

"Very surprised the ABC is even showing snippets. "
Robyn Williams kicked up one hell of a stink. Luckily everyone remembered his only science training was gained on the set of Doctor Who and promptly ignored him.

"I just wondered what happened to all those scientist who warned of global cooling 30 years ago."
I think most of them that are still alive head up the IPCC now. ;)

There are many compelling reasons in life ...... political, pragmatic, economic, health and environmental, for improving our environment, for conservation of energy and water, for developing alternative fuels to finite fossil fuels, etc, but human contributed global warming with its CO2 fear mongering is not one of them.

Monbiot is just a petite fart but assumes he is a hurricane.
