And this is a good thing! For the most of its history, Earth was much (>5F) warmer than today:

We are still technically getting out of the last ice age.

Warmer climates mean more places are warm enough to grow food. More CO2 means plants grow faster (also more food). Yea, some low lands might get flooded - either build protections or don’t buy / build houses there. But overall for humanity warmer Earth temperatures are good thing. Much better than another ice age.
