” . . . now denying “Settled Climate Science!”.”
That is not the reason given, but rather that the U.S.A. and China have refused to demonstrate obeisance to the Carbon Deity, thereby treating Canada unfairly. Boo,hoo!!
Yes, and a Republican President would be obliged to blame a U.S. withdrawal on Chinese and Indian non-participation, for the same reason. Our population believes, passionately in most cases, in the AGW creed, since they have not been exposed to the truth. Canada reached the point where they would have substantial financial liabilities, so they used U.S. and Chinese non-participation as a pretext. What would you have Harper do, expose himself as a sceptic and commit political hari kari? Surveys in both Canada and the U.S. reveal that the environment is among the top three political concerns, thanks largely to our state-controlled education systems.
