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

Craig Idso is the chairman and former president of the Center for the Study of Carbon Dioxide and Global Change (Co2Science.org). The center's claimed mission is to “separate reality from rhetoric in the emotionally-charged debate that swirls around the subject of carbon dioxide and global change.”
The Center's publication is CO2 Science, a weekly magazine that features articles questioning the science behind man-made climate change. Craig's father Sherwood B. Idso is currently the president of the Center for the Study of Carbon Dioxide on Global Change, while his brother, Keith Idso, is the Center's Vice President.
Craig Idso served as Director of Environmental Science at Peabody Energy from 2001-2002 in St. Louis, MO. According to ExxonSecrets, Craig and Keith Idso produced a report for the Western Fuels Association titled “The Greening of Planet Earth Its Progression from Hypothesis to Theory” in January, 1998. 
Stance on Climate Change
The following are some of the key points made by the Center for Carbon Dioxide and Global Change: 
“A weak short-term correlation between CO2 and temperature proves nothing about causation.”
“Strong negative climatic feedbacks prohibit catastrophic warming.”
“Growth-enhancing effects of CO2 create an impetus for cooling.”
“There is no evidence for warming-induced increases in extreme weather.”
“Elevated levels of atmospheric CO2 are a boon to the biosphere.”
“Atmospheric CO2 enrichment brings growth and prosperity to man and nature alike.”
“The Industrial Revolution has been a tremendous boon to humanity, as it has lifted large numbers of our kind from poverty to prosperity. It has also helped the rest of the biosphere - and thereby us once again - via the powerful aerial fertilization effect of the carbon dioxide that has gone into the atmosphere as a consequence of the burning of fossil fuels. Indeed, it's been win, win, win for all of life; and if there's ever been a recipe for success, this is it.” 
“Despite thousands of scientific articles affirming numerous benefits of rising temperatures and atmospheric CO2, IPCC makes almost no mention of any positive externalities resulting from such…Climate Change Reconsidered II corrects this failure, presenting an analysis of thousands of neglected research studies IPCC has downplayed or ignored in its reports so that scientists, politicians, educators, and the general public can be better informed and make decisions about the potential impacts of CO2-induced climate change.”

DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.
Idso is a lead author of the Nongovernmental International Panel on Climate Change’s (NIPCC) report entitled, Climate Change Reconsidered II: Biological Impacts, published by the Heartland Institute on March 31, 2014. Other lead authors include prominent deniers, Sherwood Idso and S. Fred Singer. 
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.
Idso is a lead author of the 2011 Interim Report of the Nongovernmental International Panel on Climate Change (NIPCC), published by the Heartland Institute. 
Other lead authors include prominent climate skeptics Robert M. Carter and S. Fred Singer. Other contributors included Joseph D‘Aleo, Indur Goklany, Sherwood Idso, Madhav Khandekar, Anthony Lupo, Willie Soon, and Mitch Taylor.
According to SourceWatch, Idso was a featured speaker at the 2011 American Legislative Exchange Council (ALEC) Annual Meeting, speaking at a workshop initially titled “Warming Up to Climate Change: The Many Benefits of Increased Atmospheric CO2” but which was renamed “Benefit Analysis of CO2” 
He was joined by fellow climate skeptics Roger Helmer and Robert Ferguson. The workshop was hosted by ALEC's Energy, Environment and Agriculture Task Force.
Spoke at the Heartland Institute's Sixth International Conference on Climate Change. His speech was titled “Co2-Induced Global Warming: Is the IPCC Presenting an Honest Assessment of the Evidence?”

Idso's signature is displayed alongside a full-page ad funded by the CATO institute that appeared in numerous newspapers including the Washington Post, the New York Times and the Chicago Tribune in 2009.
The advertisement criticizes President Obama's declaration that “few challenges facing America and the world are more urgent than combating climate change,” saying that “with all due respect Mr. President, that is not true.” It goes on to describe how “there has been no net global warming for over a decade,” and that the dangers of global warming are “grossly overstated.” 
Co-authored a report entitled “Enhanced or Impaired? Human Health in a CO2-Enriched Warmer World” (PDF) with his father Sherwood Idso and brother Keith Idso.
The report argues that global warming and an increase in atmospheric CO2 would be a boon to humanity.

*The Center for the Study of Carbon Dioxide and Global change responded to the question of whether they were funded by the Western Fuels Association as follows:
“In spite of what you think, you could be wrong. But as we do not divulge this information, you may also continue to think that you are right. In either case, we are not inclined to confirm or deny your conclusion…”
Idso has published three documentaries with the Center for the Study of Carbon Dioxide and Global Change: Carbon Dioxide and the Climate Crisis: Reality or Illusion?, Carbon Dioxide and the Climate Crisis: Avoiding Plant and Animal Extinctions, and Carbon Dioxide and the Climate Crisis: Doing the Right Thing.
