How will climate change affect regions?
It will primarily affect climate and weather.
A change in the regional climates may cause further changes in the type of life that can survive. Things will change, but not necessarily catastrophically or irreversibly. A change from our current accepted “comfort zone” causes a lot of anxiety, but nature doesn’t care about that.
The geologic cycle of growth, expansion, overuse, collapse to regrowth will continue. We cannot either create nor destroy matter, and the entropy of the universe will always increase.
