I agree with the GW skeptics. The world has been warming since the last ice age but not because of anything man has done.
However, I do disagree with your prediction statement. It's impossible to know the which card will turn up next in Black Jack or what the next roll of the dice will be in Craps, but casinos make billion of dollars knowing what the long term results will be.
It's also impossible to know what the stock market will do over the next several days; but it does not follow that the market will be higher in 10 or 20 years from now.
Only because they blacklist the Black Jack card counters.
