Politician Climate Deniers

Both the [Canadian] cabinet and the Conservative parliamentary caucus are heavily populated by politicians who deny mainstream climate science. The Conservatives have slashed financing for climate science, closed facilities that do research on climate change, told federal government climate scientists not to speak publicly about their work without approval and tried, unsuccessfully, to portray the tar sands industry as environmentally benign.
