Climate models used to explain formation of Mars valley networks

> The extensive valley networks on the surface of Mars were probably
> created by running water billions of years ago, but the source of
> that water is unknown. Now, a team of Penn State and NASA researchers
> is using climate models to predict how greenhouse warming could be
> the source of the water.
>
> "Everyone is looking for life on Mars, and if Mars was habitable
> early on as indicated by flowing water, then the chances of there
> being some sort of life there now goes up," said Natasha Batalha,
> graduate student in astronomy and astrophysics, Penn State. "Our work
> involves using models to best estimate what was happening on the
> surface of Mars 3.8 billion years ago."
>
> Previous studies analyzing craters support the idea of flowing water
> on early Mars but still unknown is how surface warming occurred to
> melt that water and how much water was really there.
>
> "If we compare some of these valleys on Mars to what we know on
> Earth, for example the Colorado River, then they look to be the same
> width," said James Kasting, Evan Pugh Professor of Geosciences, Penn
> State. "We know how much water it took to carve the Grand Canyon
> based on five to six million years of rainfall, which is estimated to
> be about three to six million feet (of rainfall)."
