In her first extensive interview since her work was dropped from Newt Gingrich's next book, Katharine Hayhoe, an atmospheric scientist at Texas Tech University, defended climate science and criticized the politicization of the issue. Hayhoe spoke to The Guardian,  saying: "I really, really deplore the politicization and polarization of this issue. There are these increasingly unprincipled attempts to polarize the science when the science is fact -- like the sky is blue, the grass is green and the temperature of our planet is increasing."
Gingrich is getting ready to publish a collection of essays on environmental issues, and Hayhoe had been included. But she was dropped after Rush Limbaugh criticized her inclusion. National Journal  published an article about, and video of, Gingrich being approached by a would-be supporter who had heard Limbaugh's criticism, and who was reassured when Gingrich assured her that the essay would be removed from his book.
