Before Earth´s oceans ever have a chance to freeze or fry, they might have already dried up and evaporated into space, said James Kasting, a Penn State professor of meteorology and geosciences. Kasting estimates his version of the end is a mere 1 billion years away.

"The sun ... is getting brighter with time and that affects the Earth´s climate," Kasting said. "Eventually temperatures will become high enough so that the oceans evaporate."

And, Kasting said, a cataclysmic finale may come even sooner. As Earth becomes a global desert, carbon dioxide levels are expected to drop. At a certain level, which he and his colleagues say might be achieved in half a billion years, there would not be enough carbon dioxide to support photosynthesis, and most plants would die.

Remaining plants would not be sufficient to support a biosphere, Kasting contends. So while the entire planet might incinerated in a few billion years, or cast off into a deep freeze, it´s possible that life on Earth is already in the sunset years.

"If we calculated correctly, Earth has been habitable for 4.5 billion years and only has a half-billion years left," Kasting said.


A ver si caen de una vez 30 o más centímetros de nieve en Madrid capital.
