Given the relative stability of this planet's climate over billions of
years, there must be some pretty powerful negative feedback forces
holding things in balance.  There have been periods with much higher
temperatures and CO2 levels than we have now (or are forcast to have),
and life did not die out.

I don't subscribe to the extremist view that the world is doomed - it
will just continue to change, as it always has.

There are plenty of models that show all sorts of odd effects when the
temperature goes up - more rainfall for one (which could make some
currently dry areas suitable for farming).  Higher Co2 levels should
lead to more plant growth - locking at least some of the additional
Co2 away.
