Howard defends actions on Kyoto protocol - ABC News (Australian Broadcasting Corporation)

Mr Howard has told ABC1's The Howard Years program that ratifying the Kyoto protocol would have put Australia at an economic disadvantage.

"If we had gone full bore on the Kyoto we could have put our industry at a competitive disadvantage against competitor countries like China," he said.

Mr Howard has described the push for his government to sign the Kyoto protocol as a "classic example" of the "politics of symbolism"

"My suspicion is that as time goes by there will be increasing doubts raised in the community about whether everything said in alarmist terms about climate change is correct," he said.

Had I not been working down in the meteorological-climate trenches for more than 50 years, I'm sure I would have been more open to his arguments.

Most of my older colleagues with similar experience are skeptics of the human-induced global warming scenarios. I find that the climate change we have witnessed over the last century and the last 30 years is primarily a result of deep global ocean current changes that are as yet not well understood.

Water vapor, not CO2, is by far the strongest of the atmosphere's greenhouse gases. The primary issue in human-induced global warming is the question of how rising levels of atmospheric CO2 will influence upper tropospheric water vapor content. The global models, which are largely driving the global warming scare, assume upper level water vapor will sharply rise as CO2 amounts increase. The observations indicate otherwise. Humans can cause only a small amount of global temperature increase and we can do little about the rising levels of CO2. By following Ringler's advice, Fort Collins and our country would lose economically and gain little or nothing in climate benefit.
