David Evans, Carbon Accounting Modeler, Says It’s a Scam « JoNova: Science, carbon, climate and tax
Dr David Evans’ address to the Anti-Carbon-Tax rally, Perth Australia, 23 March 2011.
Good Morning Ladies and Gentlemen.
The debate about global warming has reached ridiculous proportions and is full of micro thin half-truths and misunderstandings. I am a scientist who was on the carbon gravy train, understands the evidence, was once an alarmist, but am now a skeptic. Watching this issue unfold has been amusing but, lately, worrying. This issue is tearing society apart, making fools and liars out of our politicians.
Let’s set a few things straight. The whole idea that carbon dioxide is the
main cause of the recent global warming is based on a guess that was proved false by empirical evidence during the 1990s. But the gravy train was too big, with too many jobs, industries, trading profits, political careers, and the possibility of world government and total control riding on the outcome. So rather than admit they were wrong, the governments, and their tame climate scientists, now cheat and lie outrageously to maintain the fiction that carbon dioxide is a dangerous pollutant.
Let’s be perfectly clear. Carbon dioxide is a greenhouse gas, and other things being equal, the more carbon dioxide in the air, the warmer the planet. Every bit of carbon dioxide that we emit warms the planet. But the issue is not
whether carbon dioxide warms the planet, but
how much.
Most scientists, on both sides, also agree on how much a given increase in the level of carbon dioxide raises the planet’s temperature,
if just the extra carbon dioxide is considered. These calculations come from laboratory experiments; the basic physics have been well known for a century.
