Because of its proximity to the Sun, the planet is waiting irreversible greenhouse effect on Venus Bashny.Net

Recent research staff of the University of Victoria in Canada, show that greenhouse effect on Earth's atmosphere much more than previously thought.

Our planet is located close enough to the Sun, in the future, heat and light activity of the latter has turned Earth into a kind of giant bath. Saturated steam atmosphere will reflect the thermal radiation from the fiery rays of the sun the Earth's surface, thereby exacerbating the greenhouse effect and launching a self-reinforcing cycle of heating.



Tyler Robinson and Colin Goldblatt created a model in which a planet with "earth" the relationship between received and delivered by solar energy can be a long time to keep a stable climate, or to become a cradle of environmental catastrophe, like Venus. According to Goldblatt and Robinson, a combination of factors that are favorable for life, is very rare, so few so-called extrasolar planets that astronomers have had to declare a "potentially habitable", in fact can not serve as a place of origin of life.

According to Tyler Robinson:

«The range of suitable conditions is very narrow. If earlier it was believed that the closer to the luminary, the better for life, it is now clear that the greenhouse effect can also prevent its occurrence ».

blockquote> Previously, astronomers and astrobiologists believed that the Earth is too far from the Sun to the scenario events developed irreversible greenhouse effect on Venus. According to the latest rough estimates of researchers, irreversible phase can begin on our planet, even before the most pessimistic estimates - at 0, 5-1, 1 billion years (instead of 1, 1-2, 2 billion as previously thought).



By the way, scientists believe that human-induced CO2 emissions can not affect the development of the "greenhouse of events": to speed up the process, humanity needs to burn 10 times more fossil fuel than is contained in all the planet's reserves.
