Just over a month before the United Nations convenes on September 23 in New York City to discuss climate change and activists gather for a week of action, the Obama White House Council on Environmental Quality (CEQ) argued it does not have to offer guidance to federal agencies it coordinates with to consider climate change impacts...read more

According to his profile at the Energy Advocate, Hayden's research focus was “ionic & atomic collisions; charge transfer, ionization, energy loss, energy-level crossings, ion-surface collisions, ion implantation, relativity considerations” and “energy for society.”
Stance on Climate Change
According to Hayden, “The previous predictions about the horrendous warming the people expected has not come to pass… . so it's just pure garbage. There's no reason to believe any of it.” 
The Energy Advocate, which Hayden edits, states: “Perhaps there is global warming, and perhaps there is a human influence, and perhaps that is bad. But we are not on the global-warming bandwagon… . There is no credible evidence that the temperature rise of the last century is anything out of the ordinary, and even less that a warmer earth would be less habitable than it is now. Nor will we attempt to scare readers with sea-rise, for it amounts to only the thickness of a nickel per year, as it has for millennia.” 
“The sun is now cooling and the past 60 years have shown the highest solar activity in the last 1400 years. So, yes the sun is now cooling, it has been warmer, and we can expect some cooling. But there's also some change in the ocean currents that's periodic so there is expected to be some cooling within the next decade or so. And temperature history also shows that since January, 2001, the temperature of the Earth has basically held almost flat.”

DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.
May 21 - 23, 2012
DeSmogBlog researched the co-sponsors behind Heartland's ICCC7 and found that they had collectively received over $67 million from ExxonMobil, the Koch Brothers and the conservative Scaife family foundations.
Hayden was a speaker at the Heartland Institute's 2009 International Conference on Climate Change.
Of the 65 event sponsors, 16 of them collectively received over $40 million from oil companies, especially ExxonMobil, as well as from numerous right-wing foundations such as Koch Family Foundations and Scaife Foundations.
- “A warmer world is a better world. Look at weather-related death rates in winter and in summer, and the case is overwhelming that warmer is better.”
- “The higher the CO2 levels, the more vibrant is the biosphere, as numerous experiments in greenhouses have shown. But a quick trip to the museum can make that case in spades. Those huge dinosaurs could not exist anywhere on the earth today because the land is not productive enough. CO2 is plant food, pure and simple.”
- “CO2 is not pollution by any reasonable definition.”
- “A warmer world begets more precipitation.”
- “All computer models predict a smaller temperature gradient between the poles and the equator. Necessarily, this would mean fewer and less violent storms.”
Hayden appeared on the Alex Jones show discussing “the global warming hoax.” Among Hayden's assertions were that: “Yes, the polar ice caps are shrinking … on Mars.” He also claimed that “Overall the total polar bear population has been holding steady or slightly increasing.”

Hayden was a signatory to a 2007 open letter to UN Secretary-General Ban Ki-Moon that asserts “it is not possible to stop climate change, a natural phenomenon that has affected humanity through the ages.” The letter also concludes that “the IPCC’s conclusions are quite inadequate as justification for implementing policies that will markedly diminish future prosperity.” 
According to a search of 22,000 academic journals, Hayden has not published any research in a peer-reviewed journal on the subject of climate change.
In 1996, Hayden authored an article stating that the science around the hole on the O-zone layer was “shaky.”
Hayden is the editor and publisher of a monthly newsletter called the The Energy Advocate. The Energy Advocate describes itself as “a cross between an educational blurb and a bottle of salsa. We make no apologies for being pro-science, pro-technology, pro-energy — and especially, pro-nuclear.”
Hayden has also authored two books through Vales Lake Publishing, a business registered by Hayden himself. His books are A Primer on CO2 and Climate (2007) and The Solar Fraud: Why Solar Energy Won't Run the World (2005). A Primer on CO2 discusses what Hayden believes are the major failures of current climate models.
