He's a BA/MA/PhD in economics. There's not a "science" class in his is course load. Because you are good at math/stats doesn't mean you know a thing about climate, meteorology or the other sciences involved in climate study. He can crunch the numbers, and tell you the trend without context, no question. His interpretation of those numbers is HIGHLY influenced by his unabashed and blatant right-wing/political agenda, being a fellow at the Fraser Institute shows exactly where his philosophical leanings lay. He's one of the smartest climate change deniers out there, but that doesn't make him a credible source for information about the environment. I will listen to what he has to say, as I do anyone else, but I will be the person who has made their life's work the study of the climate, who does hands-on research and interprets their own data. To say he's spouting his truth is accurate. To call his truth "The" truth is a point of view, not a fact.
Based on what I have learned and read from all sides, there's a problem, and it's going to get a lot worse unless we do something about it. Is it imminent death to the human race, nope. Is it something we need to pay attention to? We would be stupid not to. There's no other planet waiting if he fuck this one up. I don't scream from the rooftops, or rant and rave like some, but I remember being able to have a hockey rink in my backyard all winter. Can't do that now for more than a couple of weeks during the winter in Southern Ontario now, or even Alberta.
