Description: Aside from ethical concerns turning the planet Mars into a habitable planet would be a scientific challenge. The planet is too cold, lacks a useable atmosphere, and the lack of a magnetic field leaves it susceptible to space weather. Increasing the amount of CO2 in the atmosphere could solves two of these problems through the greenhouse effect. This thought-experiment could provide students an opportunity to better understand interactions between Earth systems.
