So for you the issue is all about who's to blame, not about how to
mitigate it?


I don't think anyone's to blame and it doesn't need to be mitigated. Why do
you conclude that global warming, whether man-made or natural, is
necessarily bad?


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....

You should really view the movie.
