Magnetic shield ‘would let Mars terraform itself’

Jim Green, the Chief Scientist, proposed a plan to geoengineer Mars by placing a massive magnetic shield between Mars and the sun. This shield would protect Mars from solar particles, allowing the planet's temperature and pressure to rise. As a result, carbon dioxide on Mars' polar caps would sublimate, enhancing the greenhouse effect and initiating a terraforming process. This would eventually enable humans to grow food and walk on Mars without spacesuits.
