Since we all know the earth has had many cycles of heating and cooling, I'd like to know what the optimal temperature for the planet is, anyway.....

Further, I'd like to know why I should believe someone's forecast for the next 100 years, when they can't come close to telling me what's going to happen 3 days from now with any degree of accuracy.

And if man is the cause of global warming, how do you explain this?

So many questions, so little time to fish.
