I find that kind of discourse amusing. Amusing as in, it makes me want to skin a dog alive. Just because the most alarmist, extreme predictions (Arctic ice cap being completely melted in 2014 anyone?) were way off doesn't mean it suddenly doesn't exist. I can accept the notion of global warming not being observable to the same extent everywhere, but just personal experience, if nothing else, is enough to tell me that it's for real. Our winters are much warmer than they were when I was a kid, and even back then they were warmer than when my parents were kids themselves. I don't even need exact numbers to tell you that, which is scary.
What's especially sad is that the anti-global warming discourse lacks any kind of scientific rigor. Studies that show it exists are somehow always false because of this and that, yet studies that show it don't are always perfectly executed and thorough. As I said at the beginning, the opposite point of view isn't really excusable either - it's far more likely that the truth isn't as catastrophic as worst-case scenarios would have you believe, but not as encouraging as the other end of the spectrum suggests.
I was amused, a few years ago, to find out that the fossil fuel industry actually buys advertisement space/time in the United States, especially during the electoral season. I guarantee you this shit would never fly in Canada (or at least in Quebec), it would be an enormous scandal. And the fossil fuel industries know this, so they resort to alternate means of propaganda. For example, they have so-called "editorialists" write in major newspapers to try and discredit the notion of global warming. They're quite easy to identify: they only ever write on global warming, and nothing else, as if they had some sort of unholy fixation on the subject. Almost as if they were incapable of talking about current events, and had no opinion on anything but that. It's a lot more subtle than just saying "hi, I'm big oil, buy my shit", but anyone with a keen enough eye can detect these bullshit salesmen.
And that's yet another reason why you yourselves have to make a bit of critical thinking, and not let anyone spoonfeed you "truths" - one way or the other.
