It's safe to say most of us know less about the real causes of global
swings in temperature, water level and depth of the ice sheets than we

a good deal more complicated and involve long term swings as well as
short term man-made causes. I find it interesting for instance that
while Glacier Bay in Alaska has continued to deepen since it was
discovered in the 1800's while glaciers around it continue to grow.


These people claim that greenhouse gases are at a level not seen for
650,000 years.

In a matter this important, if we are to err, it should be on the side
of caution, not extinction. Bush disagrees.
