A Canadian paper with no reason to lie about it reports a new survey which shows there are more polar bears than formerly thought, and their numbers appear to be growing! How about that, global cooling fans?
Seriously, I've no idea whether the planet is warming, cooling, or engaging in the normal year to year variations that we call "weather." My point is that people like Al Gore who claim to be certain are employing faith, not fact, in reaching their conclusions. Faith is okay, as long as we recognize it as such.
In other words, we simply don't know with any scientific certainty what the climate is doing, or whether humans are having any significant influence thereupon. A healthy Canadian polar bear population suggests maybe things aren't so bad, eh? See The Globe and Mail article here.
