If our planet were just a little closer to the Sun a runaway - TopicsExpress



          

If our planet were just a little closer to the Sun a runaway greenhouse effect would render it unliveable, a climate model suggests. The simulation, which helps to define the inner edge of a star system’s habitable zone, drastically reduces the fraction of Sun-like stars that might harbor a rocky planet suitable for life, some scientists suggest. But others note that the model, although detailed, might be too restrictive because it applies only to Earth-like planets on which water is abundant - Sid Perkins for Nature.
