On MSNBC, the director of the conservative Independent Women's Forum dismissed climate change as a “new science,” ignoring the fact that the science behind global warming dates back to the 19th century and has accumulated to an overwhelming body of evidence over the last three decades.

Those seeking to delay action on environmental issues have long resorted to the argument that we need to study this issue more before we act. A classic example of this came Wednesday during a segment on MSNBC with Bill Nye “The Science Guy” and Sabrina Schaeffer, the executive director of the industry-funded Independent Women's Forum. Schaeffer said that she opposed Gina McCarthy's nomination to head the Environmental Protection Agency because she may implement rules that would restrict greenhouse gas emissions from power plants. Schaeffer insisted that although she opposes this effort to curb climate change, she is a “believer in science” and “the use of experiments and randomization.” But when Nye pressed her on whether she accepts climate science, she dismissed it as a “new science” that needs further study:

Schaeffer's comments echo conservative media outlets such as The Wall Street Journal that continue to argue that we don't know enough about climate change to warrant action, despite warnings from the National Academy of Sciences and the Intergovernmental Panel on Climate Change:

But we've known about the greenhouse effect for nearly two hundred years, we've known that humans can enhance that effect by making the greenhouse gas carbon dioxide since 1895, we've known that many scientists have predicted a warming trend since the 1970's, and we've known that the National Academy of Sciences has called for “action” since 2005. To dismiss all of the evidence that has led to a consensus on manmade climate change as a “new science” is anti-science, no matter how much you love random samples.
