Excuse me for reiterating a point I have raised in another thread but
just adapted to this context.

I guess so too.
Though not scientifically very certain, climate changes with magnitude
like 3 K in 100 years (but not for longer duration with the same rate
like 30 K in 1000 years) do not seem rare in the geological history,
even if limited within the times since humans appeared. Therefore such
changes, in themselves, do not seem "bad" to the ecosystem as a whole,
though they may lead to extinction of some unlucky species.
But the current problem is that climate change occurs in the presense
of the huge popluation of human beings and its "ecological footprint"
which has reduced the adaptability (especially by way of migration) of
the ecosystems (including ourselves!). This combination is bad.
If we need to single out one factor from the compound, perhaps the bad
one is presence of ourselves, not climate change. But we cannot accept
the logical conclusion that we should be eliminated.
A viable direction seems to be to reduce our ecological footprint so
that the ecosystem can regain adaptability.
