Earth's lifespan has decreased: only half a billion more years

Until now, scientists believed that this process would only occur in five billion years, but it turns out that much earlier we will leave the zone of life

The fate of the earth is bleak - scientists today estimate that the earth will eventually dry up and burn, although it is still too early to make final plans. This terrible scenario will not happen until at least 500 million years from now.

Scientists discussed the end of the earth at the annual meeting of the American Association for the Advancement of Scientific Thought, which is currently taking place in Washington. Prof. James Casting, lecturer in Geological Sciences at the University of Pennsylvania, explained that the fate of the Earth depends on the Sun, and that, like any other planet, will not live forever. Casting explained that the sun gradually becomes hotter and has stronger radiation, which causes a gradual increase in the temperature of the earth as well. The disaster will occur when the temperatures on Earth reach 52 degrees Celsius. At this temperature the oceans will begin to evaporate.

Until now, scientists believed that this process would only occur in five billion years, but new calculations performed show that the end of the earth is closer than expected and it will occur in about 500 million years "only".

According to another scenario that predicts the end of the earth, the rise in temperatures on the earth's surface will cause the oceans to absorb the carbon dioxide from the atmosphere. In this way, the gas necessary for the existence of the plant on the earth will disappear, all the plants will die and in their wake all the living creatures that depend on the oxygen emitted by the plants will die.

"If our calculations are accurate," Casting added, "the Earth began to be habitable 4.5 billion years ago and has only half a billion years left."
