A while back, I read about a couple of scientists, who had written an article about terraforming Mars. Their theory was to send a fungus with a black pigment to the frozen poles on the planet, that had the capability of multiplying rapidly and surviving the harsh temperatures. In a couple of decades, the surface would literally become darker, and automatically absorb warmth from the sun. This in turn would melt the poles, creating a denser atmosphere where life could evolve.
