I have neither the time nor the expertise to do that. Instead, I rely on the counsel of those who do it for a living. When the predictions made by those people consistently fail to reflect reality, at what point is it OK for me to show signs of skepticism?
I'm curious... What events got you into an extremely skeptical frame of mind? Please be specific.
Most of the overturned predictions were years out before they'd have very direct and visible effects on most westerner's lives. Right now we're just in the beginning-of-climate-instability part of it.
But to answer your question specifically: I've been skeptical since day 1, and I encourage you to be the same. But part of being skeptical is "being convinced by the research and evidence" and "making an honest attempt to learn about the subject."
The hurricane business is a perfect example. It was only a couple of days ago that Al Gore beat that particular drum in his NYT editorial.
And there really is a HUGE amount of data on the subject. The current state of climate research has moved past the argument about "is there warming?" Because there is, we've found a ton of data to validate it. We're up to a very high degree of certainty that this is not purely cyclical (although more data obviously improves this confidence).
Where the research continues to grind is on specific effects of warming (such as this hurricane issue) and specific feedbacks in the system that can either slow or speed the rate of climate change. You see a lot of things about that now in the news now, but you may notice that there is much less discussion of "if the hockey stick really exists."
I'd also like to ask why you care what Al Gore says? He's a poster child and a ideologue for a specific political group. I certainly don't care what he says. He's not making scientific claims that are worth addressing. How he got a Nobel I will never know.
