Dr. James F. Kasting, professor of geosciences and meteorology at Penn State University, said Friday that he believes there was not enough time available for short lived asteroidal impacts to have caused the valleys and "water-created" formations on Mars. He states that the most likely method of this continuous warming effect would be from the greenhouse effect, although a pure CO2-water greenhouse effect would not have been enough to melt water.
