A study titled "Radiative-convective model of warming Mars with artificial greenhouse gases" by Margarita M. Marinova, now at California Institute of Technology, Pasadena, California, USA; Christopher P. McKay, NASA Ames Research Center, Moffett Field, California, USA; and Hirofumi Hashimoto, University of Tsukuba, Tsukuba, Japan, suggests that when we finally get to Mars we might be able to use the global warming to terraform Mars to make it habitable for humans.

The researchers found that a compound known as octafluoropropane, whose chemical formula is C3F8, produced the greatest warming, while its combination with several similar gases enhanced the warming even further. They think that adding approximately 300 parts per million of the gas mixture in the current Martian atmosphere, which is the equivalent of nearly two parts per million in an Earth- like atmosphere, would spark a runaway greenhouse effect, that would slowly evaporate the frozen carbon dioxide on the planet's surface. The global warming and the ensuing release of that carbon dioxide would lead to further melting and global temperature increases that could create a thicker atmosphere to the planet.

The researchers warn, though, that this process could take hundreds, even thousands, or years to complete.

Obviously, they're wrong. Global warming on Earth will wipe out humanity in a few years, if you beleive the extremists. If we act now, and get those greenhouse gasses on Mars now, we can get have shirt-sleeve weather by the time we arrive.
