Dear Craig and all:

Well, this is quite a contribution!  I'm going to try to take on one 
issue at a time, as that's about all my poor brain can handle.

I'm going to advance the proposition that more direct anthropogenic 
effects may be more important than those which might affect climate 
change, and that changing our habits will have many other benefits 
beyond climate change.

I don't have good data about Great Basin and Southwest fire history, 
but even if I did, the standard measurements might not be adequate 
for any kind of real understanding of the phenomena involved, and 
might even be misleading.  Data over a long period would be necessary 
to see any trends, and the complexity of the issue might still be 
more confusing that revelatory.

But, for starters, I would like to see the theoretical foundations 
and the data from which the " . . . $10 billion a year for 20 years . 
. . " was derived.  I don't necessarily doubt those figures, I just 
want to know how they were constructed.

I will attempt to respond to other points under different subheadings.
