Welcome to the real world

"I devoted six years to carbon accounting, building models for the Australian Greenhouse Office. I am the rocket scientist who wrote the carbon accounting model (FullCAM) that measures Australia's compliance with the Kyoto Protocol, in the land use change and forestry sector. (…) When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty good. (…) But since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming. (…) Most of the public and our decision makers are not aware of the most basic salient facts:

1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it. (…) 2. There is no evidence to support the idea that carbon emissions cause significant global warming. None. (…) 3. The satellites that measure the world's temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6 ºC in the past year (to the temperature of 1980). (…) 4. The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. (…) None of these points are controversial. The alarmist scientists agree with them, though they would dispute their relevance."
