Washington, D.C., April 1, 2011 – The scientific hypotheses underlying global warming alarmism are overwhelmingly contradicted by real-world data, and for that reason economic studies on the alleged benefits of controlling greenhouse gas emissions are baseless. That’s the finding of a new peer-reviewed report by a former EPA whistleblower.
Dr. Alan Carlin, now retired, was a career environmental economist at EPA when CEI broke the story of his negative report on the agency’s proposal to regulate greenhouse gases in June, 2009. Dr. Carlin’s supervisor had ordered him to keep quiet about the report and to stop working on global warming issues. EPA’s attempt to silence Dr. Carlin became a highly-publicized embarrassment to the agency,  given Administrator Lisa Jackson’s supposed commitment to transparency.
Dr. Carlin’s new study, A Multidisciplinary, Science-Based Approach to the Economics of Climate Change , is published in the International Journal of Environmental Research and Public Health. It finds that fossil fuel use has little impact on atmospheric CO2 levels. Moreover, the claim that atmospheric CO2 has a strong positive feedback effect on temperature is contradicted on several grounds, ranging from low atmospheric sensitivity to volcanic eruptions, to the lack of ocean heating and the absence of a predicted tropical “hot spot.”
However, most economic analyses of greenhouse gas emission controls, such as those being imposed by EPA, have been conducted with no consideration of the questionable nature of the underlying science. For that reason, according to Dr. Carlin, the actual “economic benefits of reducing CO2 emissions may be about two orders of magnitude less” than what is claimed in those reports.
Sam Kazman, CEI General Counsel, stated, “One of the major criticisms of Dr. Carlin’s EPA report was that it was not peer-reviewed, even though peer-review was neither customary for internal agency assessments, nor was it possible due to the time constraints imposed on Dr. Carlin by the agency. For that reason, we are glad to see this expanded version of Dr. Carlin’s report now appear as a peer-reviewed study.”
