WASHINGTON, DC – Sen. James Inhofe (R-Okla.), Chairman of the Environment & Public Works Committee, delivered the final of four major speeches today on the issue of climate change. Inhofe, a prominent skeptic of the science behind global warming, engaged over the last several weeks in a series of four speeches to debunk what he describes as the “four pillars of climate change alarmism.” The fourth speech, given on the floor of the United States Senate, addressed the data produced by climate models, which alarmists claim supposedly provide irrefutable evidence of global warming “consensus.” Inhofe stated today: “It’s clear that climate models, even with increasing levels of sophistication, still contain a number of critical shortcomings. With that in mind, policymakers should reject ridiculous statements that essentially equate climate model runs with scientific truth.” “As I discussed today, climate modeling is in its infancy. It cannot predict future temperatures with reasonable certainty that these predictions are accurate. The physical world is exceedingly complex, and the more complex the models, the more potential errors are introduced into the models. We understand little about how to accurately model the troposphere and about the role of aerosols, clouds and water vapor. Moreover, there are enormous data gaps in the very short temperature records that we have. And surface data often conflict with more accurate balloon and satellite data.” The previous speeches examined the 2001 National Academy of Sciences climate report, the 2001 report by the Intergovernmental Panel on Climate Change, and the recently released international Arctic Climate Impact Assessment report.
