OK, I just finished a lousy indoor trainer "ride" because the weather is so lousy out.
The biggest signal that the global warming crisis is all hot air (he-he) is that it is so highly politicized. A crisis really helps to scare the tax dollars out of us and makes us happily give up control to "save the planet". If we really had enough reliable scientific data and environmental knowledge to say for sure that within 100 years (an interval conveniently far in the future, but not too far) we were going to wipe out 1/4 of the planet there would be no significant arguments from the political front. Instead they would all be jumping on the bandwagon to get their slice of the big pie. Our data is very poor and far to coarse even in recent (present?) times to accurately define anything like a mean earth temperature - whatever that means.
I remember listening to an NPR interview of Kary Mullis (1993 Nobel prize in chemistry) and the subject of global warming was brought up like it was a fact. He laughed and said there was no such thing and that the data simply didn't and couldn't support it. The host was absolutely speechless. I never heard Mullis on NPR again!
On the other hand I'll have a good shot personally of getting a thin slice of the global warming pie. However, I could get a much bigger slice of an asteroid defense (chicken little) pie and if we don't stop the asteroid what's the point of doing anything about global warming? How about we do the asteroid defense first and then if we have any workers still dumb enough to pay for it we'll go after the global warming?
I've really enjoyed this little bit of banter and what an appropriate topic on a day that's so cold and miserable for riding.
