This is depressing news! Scientists published a study in the journal Nature Astronomy today detailing why we absolutely cannot terraform Mars in the forseeable future with our current understanding of science and technology. The short answer is that there simply isn't near enough CO2 stored on the entire planet to be released into the atmosphere to terraform it. Apparently, adding up all the CO2 trapped in the ice and other places on Mars only gets us to 1/50 of the amount we need to thicken the atmosphere enough for Earth creatures to live there. Turns out the game Terraforming Mars may be more fantasy than science fiction. Oh well, it's still a great game.
