I for one think that the ultimate goal of our species is not to remain on Earth... let people working on life extension, and they will go away :-)
Best Way to Make Mars Habitable: Inject Greenhouse Gas
Fri Feb 4, 9:19 AM ET
The best way to make Mars habitable would be to inject synthetic greenhouse gases into its atmosphere, researchers said Thursday
Some think earthlings have no right to mess with the climate of another planet. Others see Mars as a refuge for people who might need to flee this world as conditions deteriorate. Another argument holds that Mars was likely warmer and wetter in its distant past, and it might have harbored life, so bringing it back to a previous state makes sense.
Among the ideas for how to warm Mars: sprinkling stuff near the poles that would absorb more sunlight; or placing large mirrors in orbit around the planet to reflect more sunlight onto it.
Jumpstart the warming
The new research suggests that forcing global warming by injecting greenhouse gases may be the best way to terraform, should governments decide to do so. The conditions warming Earth could be harnessed to transform Mars, the scientists determined.....
Gas of choice
The new research modeled how manmade greenhouse gases would affect Martian temperature and melt water ice and carbon dioxide ice at the poles.
Artificially created gases could be 10,000 times more effective than carbon dioxide in warming up the Red Planet, the study determined. The gases that would work the best are flourines and could be made from elements readily available on Mars, Marinova and her colleagues found.
Adding 300 parts per million of the gas mixture into the Martian air would trigger a runaway greenhouse effect,
