Pardon me if I do not know some fundamental law of physics, but is it not possible that some of the water on Earth or Mars falls from space, either as catastrophic events or on a regular basis? Thanks for helping me before I email the author...
This is inspired by a "News and Views" item in this week's Nature 458, 5 March, 2009, p. 45; "Volatility in Martian Magmas," by Harry McSween, Knoxville. It is a discussion of Filiberto and Trieman's report in Chemical Geology about chlorine replacing water as a magma volatile. Mcsween states:
"But to my mind it is doubtful that magma borne chlorine would dominate on Mars. The channels and valley networks on Mars were surely eroded by water, and magmas must have delivered that water to the surface."
Now, why can't it be considered that Mars has catastrophic floods from outer-space sources? Indeed, from what I have seen of volcanoes in Hawaii, they are a lot better at putting out rock than water. Also, I recall reading about cosmic snowballs that were destroyed by Earth's magnetic field, and it is my understanding that Mars does not have this protection...

Please see this, posted today by NASA: photojournal.jpl.nasa.gov/catalog/PIA12170This vertical profile view from the Tropospheric Emission Spectrometer (TES) instrument on NASA's Aura satellite depicts the distribution of water vapor molecules over Earth's tropics across one transect of the satellite's orbit on January 6, 2006. TES uses the spectrum of the water isotope HDO or 'heavy' water (also known as deuterium) to trace the history of the water vapor.

So is this cosmic shower evenly distributed over our planet, or does it concentrate in areas that receive a lot of rain? Do magnetic portals from the Sun have an influence?
A personal note: I am back to work after nine months on unemployment... still hoping to enroll in a UW "Sustainable Transportation Certificate" program on-line starting in October.

When god finished making the Earth, he washed his hands. He forgot to turn the tap off after he'd finished, that was 3 billion years ago...
