I’m not sure that’s true. Climate change has a good number of destroyed civilizations on its ledger.
Where I think you have a point is that climate change is less avoidable and easier to adapt to, which makes it potentially less deserving of attention.
Yes entire civilizations have risen and collapsed due to natural climate change. The difference today is that we have the technology to adapt to the changing climate.
But you don't get social cohesion without shared cultural values. Without shared values civilization devolves quickly.
