There are a number of reasons.

For instance, it is my understanding that Polar Bears are drowning
because they are too exhausted to reach sea ice that has retreated to
record levels. Should this result in a reduction in the Polar Bear
population, it will cause native peoples of the polar latitudes to
abandon their traditional ways of life.

The ice covering Greenland is currently melting at all time record
rates. That feeds a positive feedback system in which the incident
isolation is no longer reflected back into space, but absorbed by the
exposed land leading to an increase of environmental temperatures.
That accelerates melting.

If the less dense melt water dilutes the mineral laden sea water at
the poles, it is possible that it may disrupt the ocean current
"conveyer" that causes the historical climates to which we are
accustomed, and it may disrupt ocean biota to the point of reducing
available nutrients for sea life....


Nobody disputes there will be changes, but you seem to believe that any
changes are necessarily bad.



You should really view the movie.


I'll stick with science.
