Four Questions.

1. What is the accepted "Normal" temperature of the globe?
2. What is considered the "Ideal" temperature of the globe?
3. Why?
4. According to who based on what "Settled Facts"?

The answer to these questions would do a lot in convincing me to change my opinion. According to some of the AGW crowd, if I am reading it right, it is a damned good thing we killed off all those wretched CO2, methane producing Bison in the 1800s, otherwise we may have cooked long ago.
