Excellent column from Mr. MacDougall: it shows that less partisan opinion pieces are more genuinely provocative and engaging.

Trump didn't just open a door for Mr. Scheer and progressive conservatives (has a nice ring, doesn't it?), he rolled out red carpet.

According to Article 28 of the Paris Agreemen, each country is committed for three years. The agreement only became effective in November 2016. The US can't officially leave until 2019 and can't withdraw until November 2020--just in time for a new president to be elected.

Trump and his advisers just found a way for him to keep his promise to his base without really keeping it, since it will certainly be reversed before it can do too much damage.

Secretary of State Tillerson confirmed as much by immediately telling the world that Trump didn't really mean what he said, calling it "a policy decision by the president ... I don't think we're going to change our effort to reduce our emission in the future."

Quite clever, actually.
