[Greenbuilding] [BULK] Re: [BULK] HCFC & HFC ozone & globalwarming

There are natural warming and cooling patterns, but science has shown that
human behavior is escalating the warming pattern exponentially.  A natural
ice age will eventually occur -- but I'd prefer it happened in a few
thousand years rather than in the next century.

On the global warming topic, a friend of mine (an engineer and life long
science buff) brought up an interesting perspective on the issue on which I
was wondering if anyone else has any insights. He pointed out that if you
look at the natural warming and cooling patterns of the earth over it's
history, that the earth is due for a ice age. His comment on global warming
is similar to Lawrence's which is that global warming will not be good, but
we humans can probably adapt to the changes. A natural ice age however would
be catastrophic for humans. Following that thought, human induced global
warming could actually be saving us from an ice age. It was a fascinating
conversation although tough to swallow the "bright side" concept; especially
during hurricane season.
