The Heartland Institute’s recent International Climate Change Conference in Las Vegas illustrates climate change deniers’ desperate confusion. As Bloomberg News noted, “Heartland’s strategy seemed to be to throw many theories at the wall and see what stuck.” A who’s who of fossil fuel industry supporters and anti-science shills...

According to his bio, Evans claims to be a “Rocket Scientist,” and one article describes him as a “Top Rocket Scientist.” While Evans's background does show that he has a Ph.D. in electrical engineering, there is no evidence that he was ever employed as a rocket scientist.
When DeSmogBlog contacted Evans regarding his claim of being a rocket scientist, Evans replied that “In US academic and industry parlance, 'rocket scientist' means anyone who has completed a PhD in one of the hard sciences at one of the top US institutions.”
Evans also claims to be “building a word processor for Windows.” DeSmogBlog contacted Microsoft and they have confirmed that he does not work for them.
Evans is an editor for the Australian edition of GoldNerds, a company that sells information about gold companies to investors. He also does private mathematics research. 
David Evans gained media attention after an article he wrote titled, “No smoking hot spot,” which was published in The Australian in June, 2008. The article claims that climate change is not caused by C02 emissions because there is no evidence of “a hot spot about 10km up in the atmosphere over the tropics.” 
From 1999 to 2006, Evans worked for the Australian Greenhouse Office designing a carbon accounting system that is used by the Australian Government to calculate its land-use carbon accounts for the Kyoto Protocol.
While Evans says in “My Life With the AGO and Other Observations” that “[he] know[s] a heck of a lot about modeling and computers,” he states clearly that he is “not a climate modeler.”
Stance on Climate Change
“The evidence supporting the idea that CO2 emissions were the main cause of global warming reversed itself from 1995 to 2006, causing Evans to move from being a warmist to a skeptic.” 
“If there is no hot spot then an increased greenhouse effect is not the cause of global warming. So we know for sure that carbon emissions are not a significant cause of the global warming…” 
“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.”

According to his resume, Evans has not published any peer-reviewed research papers on the subject of climate change.
Evans published one paper in 1987, but it was unrelated to climate change.
