Terraforming Mars - Head over to Io9 for a great article of how we could terraform Mars using our current knowledge of the Red Planet. The first step is to reintroduce liquid water to the surface, then increasing the atmospheric pressure, and that should lead to an overall increase in planet temperatures sufficient to sustain plants and someday humans.
There’s also a discussion on the issues facing the aim of a sustainable human presence on Mars, including the absence of a strong planetary magnetic field to help shield the new martians from space radiation. Another challenge is the relatively low 0.4g surface gravity.
