Climategate

[Ultraprene]

The evidence for climate change isn't just in weather records for the past hundred years or so, but in understanding the physics. The Earth "normally" has a temp about 30 deg C above that you would calculate from the Planck Theory of heat radiation. That is due to Greenhouse effect of CO2 and other gases with optical absorption bands around 10-15 microns. During the industrial age we have nearly doubled the CO2 levels in the atmosphere and the amount is about half that released by fossil fuel burning. (the rest was mostly absorbed int he oceans making them more acidic.) Isotopic analysis shows that the added CO2 came from fossil fuel. I recommend an excellent article in the Jan. 2011 "Physics Today."

If a kid is batting baseballs at a house, d owe have to wait till he has broken a window to predict that eventually he will?

Only if you can't admit that windows can be broken by baseballs. After all, have you ever seen a window broken by a baseball? Do you have any proof that the baseball can actually break the window? No, no, actually testing this theory by throwing baseballs at windows is not acceptable, because everyone knows that no one deliberately throws baseballs at windows in real life. I'll only accept real evidence of a baseball being hit by a kid and breaking a window. What? Which video is that? Oh, that's an obvious fake, made by a window maker. In league with the government to raise our taxes to pay for all the windows that aren't going to get broken anyway. It's all a conspiracy, don't you know.
