Did you know that big oil companies throughout the USA and Canada employ the same Public Relations firms that were used by the Tobacco lobby in the ’60s to deny the link between smoking and Cancer? Did you realise that the Bush White House has been systematically suppressing reports on the science of climate change, and using executive power to edit language written by scientists, to create the illusion of uncertainty where there is none? Canadians, did you realise just how deep the links between the denial machine in the USA, big oil south of the border, and Stephen Harper’s government really go?

It’s not often that I am truly impressed by a piece of main-stream investigative journalism, but this documentary from the CBC’s hard-hitting Fifth Estate series is clear, well presented, and damning in the evidence it presents. Please, watch it, and get your friends to watch it too.
