Who is concerned about climate change? I personally believe this is our biggest threat
Humans have been dealing with climate change for 1000s of years. We adapt cause that is what we do.
So here's the graphic.
The graphic correlates with GDP per captita. Those countries with functional governments and economies will do fine. Those with dyfunctional or non-existent governments will have problems. IOW - this is nothing new. The only thing climate change does is give people a boogie man to blame instead of more accurately placing the blame on the people living in the countries that are not able to create or sustain a functional government.
