Did you say "warming"? Wouldn't there be a bit of exaggeration?
When we look at the temperature readings on the last 100 years, there is no doubt that the planet is warming up.
Now, is it fatal for Humanity if we continue like this? We will not be able to live between + and - 30 ° of latitude, and with 7 billions of human our descendants will be well tightened in the high latitudes. It will be necessary to find compact ways to produce food, but it is not technologically impossible.
Our descendants will live in bubbles protecting them from heat and climate disasters.
Is it worse than Elon Musk's plan to live underground on Mars? Probably not.
Man will have just transformed the earthly paradise for a hostile planet. And then, the universe is big no? we will find another planet with oil, coal and gas. History to start the cycle again.
Or not.
