The earth is getting hotter and hotter. What will happen to human beings after a long time?

First of all, the Paleocene-Eocene extreme heat event caused the earth to rise by 5 ~ 8℃ in a very short time. How short is this time? The shortest estimate is 13 years! In just 13 years, the earth has risen by 5 ~ 8℃. Think about it again. In the past 1 years, the earth's temperature has only risen by .3℃, which makes people nervous, and they can't help blushing. It is after this incident that primates who could only live in a corner have covered the whole of Europe, Asia and Africa! If this incident did not happen, it is still a question whether primates can survive, let alone humans!

Then came the Em interglacial period, when the temperature was 5-8℃ higher than it is now, and the Sahara desert turned into a tropical rain forest. It was at that time that Homo sapiens went from Africa to the world, chopping melons and vegetables all the way and occupied the whole world! Then came 12, years ago, when the ice age ended, global warming and the temperature was about two degrees higher than it is now. Humans took this opportunity to enter the era of agricultural civilization in one fell swoop, and human civilizations were born all over the world!

finally, according to the records of ancient China, whenever the climate in China gets warmer, China will enter a prosperous time, regardless of Han and Tang dynasties! History has proved time and again that whenever global warming occurs, it is a period of rapid development of mankind. I really don't understand what those who think that global warming will destroy mankind think.

At that time, human science was well developed, and it was possible to emigrate to other planets. Why should we hang ourselves on a dead tree like the earth? According to the hierarchy theory of cosmic civilization, some scientists believe that to reach the second civilization, human beings must completely rely on solar energy, and must build a huge dyson sphere structure to absorb solar energy. To build a large shell of about 1 astronomical unit to wrap the sun, it is necessary to dismantle all the planets in the solar system, including the earth, and people's living areas have completely reached space cities or emigrated outside the solar system. This space city is attached to the dyson sphere.
