I would say that he attended all these meetings and summits and accomplished absolutely nothing worth the price of admission. The burden of proof is on you to prove 2 things: a) these meetings have a provable causal link to curbing global warming and b ) if so, when, by how much, and at what cost? Anyways, he's nothing but platitudes with socks and hair that reads a script with no original thought at all. Why on earth our government would demonize and kneecap our industries while self flagellating over our mere 1.6% of global CO2 emissions?. Especially, when Canadian advancements in carbon capture and sequestration are top notch in the world. Also, when he rambles on about Canada being important in the world (or any other bullshit about global citizenry), he is simply wrong. Canada is, and has been since 1867, a democratic nation state. It is not a "post national state"; or any template for one. In economic terms, we're about 2.2% of world GDP. Insignificant. The economy of Texas is almost as big as the economy of Canada. I would ask you to ask yourself, has Trudeau "done" anything worth a 350K/yr salary? The government isn't any more transparent, election formats didn't change, 1 MP and 1 staffer have resigned for sexual misconduct and something else that hasn't been divulged. His "tax cut for the middle class" is a pointless pittance of about 22$/wk to someone making 90K/yr (I make more than that and I'd rather that the feds not blow the 320M on that level of weak tax cut...go Reagan style or go home). Sure, granted, Bev Oda (a Conservative MP) spent 16$ on some orange juice. But, Amarjeet Sohi (a Liberal MP) spent over 800K on reno-ing his office. But, Katie Telford and Gerald Butts (un-elected bureaucrats) expensed over 200K to move to Ottawa to join the lovely high cost/low efficiency borg of a federal government. Go down the list and you'll find more examples of this government just pissing away money at a scale much greater than the Harper Conservatives could ever dream of. It isn't even a liberal party in the proper, English, sense. Its a socialist party like the one in Ontario. That might explain why NDP voters flocked to the Liberal party in the 2015 election. If you don't believe me, look at the results on wikipedia. I won't say something like "Harper was better", while that is absolutely true, it's not the point here. The point is that you're ideologically married to Trudeau and you seem to think of him going to meetings as actually constructive work on global warming because your standards are set too damn low. In summary, as Donald Trump has said: "WRONG."
