After regent Nancy Boettger warned Iowa State University last month to keep free speech in mind while teaching on the “politically charged topic” of climate science, she gave ISU a pair of books from the Nongovernmental International Panel on Climate Change – which denies the notion of human-induced climate change.

“The human impact on global climate is small, and any warming that may occur as a result of human carbon dioxide and other greenhouse gas emissions is likely to have little effect on global temperatures, the cryosphere (ice-covered areas), hydrosphere (oceans , lakes, and rivers), or weather, ”according to a summary of one of the two books Boettger provided ISU, both of which are in the“ Climate Change Reconsidered II ”series out of the NIPCC.

The two books Boettger provided Iowa State after regents approved the university’s new bachelor of science in climate science – with her free-speech warning attached – are:

  • “Climate Change Reconsidered II: Physical Science,” summarized as an “independent, comprehensive, and authoritative report on the current state of climate science” published in October 2013 and produced by the NIPCC; the Center for the Study of Carbon Dioxide and Global Change; the Science and Environmental Policy Project; and The Heartland Institute.
  • “Climate Change Reconsidered II: Biological Impacts,” published in April 2014 and produced by the same entities.

In response to The Gazette’s questions about how of if Iowa State is planning to use the materials in its new climate science program, spokesman Rob Schweers said, “The books will be shared with the Department of Geological and Atmospheric Sciences, which offers the climate science program.”

“Faculty will be free to use these resources for their courses as they see fit.”


The Nongovernmental International Panel on Climate Change is a global group of nongovernment scientists and scholars who present a “realistic assessment of the science and economics of global warming.”

“Because it is not a government agency, and because its members are not predisposed to believe climate change is caused by human greenhouse gas emissions, NIPCC is able to offer an independent ‘second opinion’ of the evidence reviewed – or not reviewed – by the Intergovernmental Panel on Climate Change (IPCC) on the issue of global warming, ”according to the NIPCC website.

The IPCC is the United Nations’ body for assessing science related to climate change, created in 1988 by the World Meteorological Organization and the United Nations Environment Program. It’s aim, among other things, is to “provide governments at all levels with scientific information that they can use to develop climate policies.”

The IPCC currently has 195 member governments. Its assessment reports undergo expert reviews, and the final product of its sixth report is due later this year or in early 2023.

An “impacts, adaptation, and vulnerability” portion of the sixth edition – which came out in February – reported the following, among its many findings:

“Human-induced climate change, including more frequent and intense extreme events, has caused widespread adverse impacts and related losses and damages to nature and people, beyond natural climate variability.”

Although some development and adaptation efforts have reduced vulnerability, “across sectors and regions, the most vulnerable people and systems are observed to be disproportionately affected,” according to the report.

In a “summary for policymakers” of the Climate Change Reconsidered II: Physical Science book that Boettger provided ISU, authors criticized the IPCC and its findings.

“Many scientists, policymakers, and citizens have become concerned over the possibility that man-made greenhouse engaged gas emissions, in particular carbon dioxide, may be causing dangerous climate change,” according to the book’s summary. “A primary reason for this public alarm is a series of reports issued by the United Nations’ (IPCC).”

The NIPCC book summary promises to interpret a “major scientific report that refutes this claim.”

Book backers

Among the entities backing the books Boettger provided Iowa State is the Science and Environmental Policy Project, established by S. Fred Singer “to challenge government environmental policies based on poor science.”

Singer – who died in 2020 at 95, according to an obituary in the New York Times – was a physicist who earned a “Merchant of Doubt” label for his arguments against the threat of climate change.

“SEPP examines questionable governmental policies, no matter how popular, to determine if policies are based on the rigorous application of the scientific method and not just a passing fad,” according to the organization Singer founded. “SEPP’s mission is to educate politicians, the media, and the public on the importance of scientific rigor in establishing environmental and related policies.”

Another backer of the books is The Heartland Institute, which calls itself an “action tank” as well as a “think tank” focused on personal liberty and limited government.

In its most recent annual report, the institute aired progress by its “Center on Climate and Environmental Policy,” which produces a “comprehensive research and education program aimed at increasing energy freedom in the United States and the world.”

“Our efforts have earned us the title of ‘the world’s most prominent think tank supporting skepticism about man-made climate change,’” according to the center, which reported making hundreds of thousands of legislator contacts in 2017 and reaching 60.9 million people through media coverage.

The Heartland Institute has drawn vocal criticism, including from the National Center for Science Education – which several years ago issued a statement debunking a mass mailing the institute sent to K-12 and college educators “promoting its new ‘Climate Change Reconsidered’ report.

“With its mailing, Heartland is encouraging teachers to use NIPCC in the classroom, as if it were a scientifically credible rival of the IPCC,” according to the center. “That wouldn’t be a good idea.”

“The NIPCC’s primary goal is to convey that there is a scientific debate about climate change,” according to the science education center. “There is not. At least three studies have shown that upward of 97 percent of climate scientists have concluded that human activity is warming the world’s climate system. “

ISU program

Iowa State reports its new bachelor’s in climate science major grew out of an urgent need for a “well-trained, adaptable workforce” to address worsening impacts of climate change – like the financial cost of “extreme events such as flooding, droughts and heat waves or widespread crop failures. “

“The program is designed to meet the needs of an ever changing world that is under considerable pressure from climate change,” according to the program description. “All students who complete the bachelor of science in climate science will have a solid foundation on how the climate system works, will be knowledgeable about climate impacts on society and relevant sustainability and mitigation options, and will be competent with data analysis and science communication. “

The university expects demand to grow, with 25 enrolling this fall and up to 120 enrolling by year five.
