How hot will it be in 2030?
Different parts of the world will warm up by 1.5˚C–8˚C. This will cause more summer heatwaves and warmer winters. Rainfall will increase by ~25% in polar and equatorial regions. The frequency and intensity of cyclones and related flooding will increase.
Will the Earth become uninhabitable?
Four billion years from now, the increase in the Earth’s surface temperature will cause a runaway greenhouse effect, heating the surface enough to melt it. By that point, all life on the Earth will be extinct.

In 1,000 years we’ll probably have a thriving civilization on Mars, the Moon, or maybe even another planet beyond the solar system. We’ve already discovered billions and billions of planets outside our own solar system. There are 40 billion Earth-like planets in our own galaxy alone.
What did the world look like 20000 years ago?
20,000 YEARS AGO. Last Glacial Maximum- a time, around 20,000 years ago, when much of the Earth was covered in ice. The average global temperature may have been as much as 10 degrees Celsius colder than that of today. The Earth has a long history of cycles between warming and cooling.
