Caneron, with all due respect, some of the data you refer to in your
post is simply not correct.

A few months ago I wrote a short article for the Rico Bugle in which I
tried very hard to summarize the issue of AGW. This article can be
accessed at www.burgy.50megs.com/climate.htm

Below I comment on some of your post:

Answer; Yes. There are several independent lines of evidence.

Answer: Yes. The first support for this came about 50 years ago with
isotope studies. I refer you to the book THE DISCOVERY OF GLOBAL
WARMING by Spencer Weart. The full text is available free online. I
bought the book.

Answer: Yes. More importantly, if such emissions are NOT curtailed, it
is possible that civilization itself will not be around in 200 years.
Admittedly, this is a pessimistic outlook; what the OPTIMISTIC outlook
is that there will be a significant sea level rise (7 meters or so)
and resulting deaths in the millions from flooding.

Answer: These tradeoffs get debated all the time on such sites as
RealClimate.org and others. Join in. Anybody may post t here.

Answer: See above. Most (not all) scientists see the current Waxman
bill as a "good start."

Comment: I agree.

Comment: It's not flawed. See discussions on RealClimate.org

Comment: See the discussions of this on RealClimate.org. Both pole ice
and Greenland ice are a factor and all are shrinking.

BTW, RealCimate is run by persons such as Gavin Schmidt who are real
climate scientists. If one posts data there that is clearly in error,
things can get a little rough.
