This is a guest post by David Suzuki.
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...

Robert H. Essenhigh
- Ph.D., Fuel Technology and Chemical Engineering, University of Sheffield (1959).
- M.S., Natural Sciences, University of Cambridge (1955).
- B.A., Natural Sciences, University of Cambridge (1951).
Essenhigh is a professor of mechanical engineering with a focus in the area of combustion. He is skeptical of the theory of man-made climate change.
Essenhigh's area of study has been the effect of chemical kinetics on the rate of coal combustion.
Stance on Climate Change
Essenhigh believes that after the next 20 years, the Earth “will begin to cool into a new ice age.”
- “'At 6 billion tons, humans are then responsible for a comparatively small amount - less than 5 percent - of atmospheric carbon dioxide,' he said. 'And if nature is the source of the rest of the carbon dioxide, then it is difficult to see that man-made carbon dioxide can be driving the rising temperatures. In fact, I don't believe it does.'” 
- “The outcome is that the global warming advocate’s conclusion on the role of CO2 evidently has it back to front: It’s the temperature that is driving the CO2. If there are flaws in these propositions, I’m listening; but if there are objections, let’s have them with the numbers.” 
“On the issue of carbon dioxide and global warming, the question at issue really is, 'Does carbon dioxide emissions from fossil fuel combustion cause global warming?' There does appear to be a common consensus view; but, the available data not only does not support this common consensus view, but supports the contrary position. That is that it is the naturally rising temperature that is driving up the carbon dioxide. This finding not only absolves man as the cause of global warming, but also raises major questions about the economic impact of attempting to control carbon dioxide emissions, particularly if this is a waste of time and resources.”

Essenhigh is a signatory to a 2007 open letter to the Secretary-General of the United Nations which claims that the “UN climate conference is taking the World in entirely the wrong direction” and that no attempts should be made to stop or slow climate change.
Signatory to a 2006 open letter to Stephen Harper titled “Open Kyoto to Debate.”
The letter suggests that global warming science is made up of “predetermined political agendas,” and states that “allocating funds to 'stopping climate change' would be irrational.”
A search of 22,000 academic journals shows that, Essenhigh has published over 45 peer-reviewed research articles mainly in the area of combustion.
According to a search of Google Scholar, Essenhigh has published two article in the area of climate change in a peer-reviewed journal. One of these publications was published in the journal Energy And Environment, a journal edited by climate change skeptic Sonja Boehmer-Christiansen. E&E has been criticized for its peer-review process, and has been one of the main journals willing to published articles by climate change skeptics.
His other publication is in Energy Fuels, a publication of the American Chemical Society, an organization that has been accused of editorial bias due to its strong ties with industry.
