Former “alarmist” scientist says Anthropogenic Global Warming (AGW) based in false science

Thanks to TIP for this post:  Also to  Bruce McQuain  for his article.

David Evans is a scientist. He has also worked in the heart of the AGW machine.  He consulted full-time for the Australian Greenhouse Office (now the Department of Climate Change) from 1999 to 2005, and part-time 2008 to 2010, modeling Australia’s carbon in plants, debris, mulch, soils, and forestry and agricultural products. He has six university degrees, including a PhD in Electrical Engineering from Stanford University. The other day he said:

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.

 The politics:

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 outrageously maintain the fiction that carbon dioxide is a dangerous pollutant.

He makes clear he understands that CO2 is indeed a “greenhouse gas”, and makes the point that if all else was equal then yes, more CO2 in the air should and would mean a warmer planet. But that’s where the current “science” goes off the tracks.It is built on an assumption that is false.

The science:

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.

The disagreement comes about what happens next.

The planet reacts to that extra carbon dioxide, which changes everything. Most critically, the extra warmth causes more water to evaporate from the oceans. But does the water hang around and increase the height of moist air in the atmosphere, or does it simply create more clouds and rain? Back in 1980, when the carbon dioxide theory started, no one knew. The alarmists guessed that it would increase the height of moist air around the planet, which would warm the planet even further, because the moist air is also a greenhouse gas. [emphasis mine]

But it didn’t increase the height of the moist air around the planet as subsequent studies have shown since that time. However, that theory or premise became the heart of the modeling that was done by the alarmist crowd.

This is exactly what I have been dreaming about, a confirmation of all the “truther’s” arguments, from an authentic source. All my plans to outline what I deemed the truth on this website have been superseded by this post. Halelulia!

I may still continue the ‘Carbon Attack’ posting because there is much detail about how temperature figures have been fudged and people being dishonest, but it not so urgent.
