Here is video of Keith Olbermann saying that "Deniers" are showing "ignorance" by citing the recent winter storms as evidence disproving global warming. (Video) Olbermann said, "the record snowfall has exposed just how ignorant leading deniers are...they think it's disproved by snow." He continued to mock people for saying that snow is evidence that there is no global warming, despite this video showing Democrats Robert Byrd, Barbara Boxer, Amy Klobuchar, and Diane Feinstein in the past all making an argument for global warming by citing warmer winters and little snow as evidence.
