In 1 billion years, there will be no liquid water on the planet's surface . Scientists expected this phenomenon to occur a few millennia earlier due to the manifest increase in solar radiation, but the latest research has postponed the death sentence for life on Earth, although the finding is not comforting for the human species, which will be extinct. long time.
According to a study by the Pierre Simon Laplace Institute (France), within an eon all the water on the planet will evaporate due to the increase in energy released by the Sun, which has been observed for 30 years. Solar radiation increases naturally during the life of any star, which in the case of the Sun, causes the rise in Earth's temperature and the slow and progressive evaporation of our most precious substance. Another expected consequence is the destabilization of the greenhouse effect, which will not allow to continue to maintain an average temperature of 15 degrees Celsius.
To date, it had not been possible to make a reliable estimate of when evaporation would occur, since very simplified astrophysical models were used, which analyzed the Earth as a uniform entity and did not take into account essential elements such as seasons or clouds. . This innovative model, however, is capable of accurately predicting the evolution of the terrestrial environment by giving a determining role to atmospheric circulation , which distributes heat along the surface.
