Canada's Minister of Climate Change, Catherine McKenna, is evidently a philosophy drop-out since she doesn’t understand that one cause produces only one effect. Minister McKenna is pushing the belief that temperatures in Canada are rising as twice the rate of the rest of the world.
I get the theory that rising CO2 traps more heat in the atmosphere, and therefore temperatures should rise. But the atmosphere being uniform requires temperatures to rise uniformly around the globe in some sense. That the chunk of the globe called Canada should be rising at twice the rate of the rest means that something other than CO2 is at play.
But what is McKenna’s response? To double down on CO2 reduction. Never mind that Canada contributes a mere 1.5 percent of global emissions, and the complete elimination of that won’t matter a whit to CO2 caused global warming. No, her response is downright Pavlovian. She can’t even be bothered ask what is causing Canada’s rate to be double, and try to address that cause.
If rising levels of CO2 causes global warming, then the uniformity of the atmosphere requires that increase to be uniform, unless some other causes are at play. If Canada’s temperatures are rising at double, then some cause other than just CO2 must be at play. Minister McKenna is so religiously fixated on CO2 that’s all she thinks about, and she won’t be rescued by that course in philosophy she missed.
