"The Church of Climate Alarm"

That's a wonderful expression - one I wish I'd thought of first! It's from the title of an article in the Sydney Morning Herald, accompanied by this splendid cartoon.

... the real fear driving climate alarmists wild is that a more rational approach to the fundamentalist religion of global warming may be in the ascendancy - whether in the parliamentary offices of the world's largest trading bloc or in the living rooms of Blacktown.

As the global financial crisis takes hold, perhaps people are starting to wonder whether the so-called precautionary principle, which would have us accept enormous new taxes in the guise of an emissions trading scheme and curtail economic growth, is justified, based on what we actually know about climate.

One of Australia's leading enviro-sceptics, the geologist and University of Adelaide professor Ian Plimer, 62, says he has noticed audiences becoming more receptive to his message that climate change has always occurred and there is nothing we can do to stop it.

In a speech at the American Club in Sydney on Monday night for Quadrant magazine, titled Human-Induced Climate Change - A Lot Of Hot Air, Plimer debunked climate-change myths.

"Climates always change," he said. Our climate has changed in cycles over millions of years, as the orbit of the planet wobbles and our distance from the sun changes, for instance, or as the sun itself produces variable amounts of radiation. "All of this affects climate. It is impossible to stop climate change. Climates have always changed and they always will."

His two-hour presentation included more than 50 charts and graphs, as well as almost 40 pages of references. It is the basis of his new book, Heaven And Earth: The Missing Science Of Global Warming, to be published early next year.

Plimer said one of the charts, which plots atmospheric carbon dioxide and temperature over 500 million years, with seemingly little correlation, demonstrates one of the "lessons from history" to which geologists are privy: "There is no relationship between CO2 and temperature."

Another slide charts the alternating periods of cooling and warming on Earth, with the Pleistocene Ice Age starting 110,000 years ago and giving way, 14,700 years ago, to the Bolling warm period for 800 years. This in turn gave way to the Older Dryas cooling for 300 years, then the Allerod warming for 700 years, and so on, until the cooling of the Little Ice Age from 1300 to 1850. Since 1850, we have lived through the "Modern Warming", one of the most stable climate periods in history.

Plimer said some astronomers predict we are headed for a new cooling period.

Plimer said there is a division between those scientists who sit in front of super computers and push piles of data into the mathematical models that drive the theory of climate change, and those who take measurements in the field.

We are not sceptical enough about the data. For instance, Plimer cited differences between results from temperature measuring stations in urban and rural areas. Those in urbanised Chicago, Berkeley, New York, and so on, show temperature rises over the past 150 years, whereas those in the rural US, in Houlton, Albany and Harrisburg (though not Death Valley, California) show equally consistent cooling. "What we're measuring is urbanisation," Plimer said.

To understand the chaotic nature of climate change, we need to consider all the inputs - cosmic radiation, sun, clouds and so on, he said.

There was much more but essentially Plimer's message is that the idea humans cause climate change has become a fundamentalist religion which is corrupting science. It is embedded with a fear of nature and embraced principally by city people who have lost touch with nature.

He likens the debate to the famous 1990s battle he had in the Federal Court, where he accused an elder of The Hills Bible Church in Baulkham Hills of breaching Australia's Trade Practices Act by claiming to have found scientific evidence of Noah's Ark in Turkey.

Plimer says creationists and climate alarmists are quite similar in that "we're dealing with dogma and people who, when challenged, become quite vicious and irrational".

Human-caused climate change is being "promoted with religious zeal … there are fundamentalist organisations which will do anything to silence critics. They have their holy books, their prophet [is] Al Gore. And they are promoting a story which is frightening us witless [using] guilt [and urging] penance."

I couldn't agree more! I'm getting very fed up with global-warming fear-mongering, particularly because so many of them seem to believe that President-elect Obama and the Democratic majority in the House and Senate will get behind their agenda and push it. It's high time we showed these false-alarm fanatics that we're onto their little game, and won't play it any more.
