The Center for the Study of Carbon Dioxide and Global Change is a 501(c)(3) non-profit organization based in Tempe, Arizona. Its stated purpose is to "disseminate factual reports and sound commentary on new developments in the world-wide scientific quest to determine the climatic and biological consequences of the ongoing rise in the air's CO2 content." The Center produces a weekly online science newsletter called CO2Science.
The Center was founded and is run by Craig D Idso, along with Sherwood B Idso, his father, and Keith E Idso, his brother. They came from backgrounds in agriculture and climate, and became involved in the global warming controversy through their study of earth's temperature sensitivity to radiative perturbations and plant responses to elevated CO2 levels and carbon sequestration. The Center is sharply critical of the position of the IPCC and believes that global warming will be beneficial to mankind.
The Center does not discuss their funding, saying, "we believe that ideas about the way the world of nature operates should stand or fall on their own merits, irrespective of the source of support for the person or organization that produces them."
According to IRS records, the ExxonMobil Foundation provided a grant of $15,000 to the center in 2000. Another report states that ExxonMobil has funded an additional $55,000 to the center. ExxonMobil stated it funded, "organizations which research significant policy issues and promote informed discussion on issues of direct relevance to the company. [...] These organizations do not speak on our behalf, nor do we control their views and messages."
Sherwood Idso attributed the funding to, "they probably liked what we typically had to say about the issue. But what we had to say then, and what we have to say now, came not, and comes not, from them or any other organization or person. Rather, it was and is derived from our individual scrutinizing of the pertinent scientific literature and our analyses of what we find there, which we have been doing and subsequently writing about on our website on a weekly basis without a single break since 15 Jul 2000, and twice-monthly before that since 15 Sep 1998 ... and no one could pay my sons and me enough money to do that."
- Medieval Warm Period Project: intended to document peer-reviewed studies of the Medieval Warm Period (MWP), and to determine:
- Was MWP global in extent?
- How warm was MWP compared to the Current Warm Period (CWP)?
- Was MWP longer or shorter than the CWP? 
- Nongovernmental International Panel on Climate Change (NIPCC), the NIPCC website states that its reports were boosted when Craig Idso agreed to combine the Center's collections of reviews of science with the work of the NIPCC which had been conceived and founded by Fred Singer.
- "The Positive Externalities of Carbon Dioxide: Estimating the Monetary Benefits of Rising Atmospheric CO2 Concentrations on Global Food Production", published 18 October 2013. Full copy online: . The report estimates that the extra value that the rise in atmospheric CO2 has produced from 1961 – 2011 is equivalent to a cumulative $3.5 trillion in increased crop production, from CO2 fertilization.
