Anyone else read the Kim Stanley Robinson “Red Mars, Green Mars, Blue Mars” trilogy? Anyone ever bothered by the fact that he got the colours the wrong way around? If we terraform Mars, we’ll cook it for 100 years with super-greenhouse gases and the CO2 poles will melt and the CO2 in the regolith will sublime. This gives Mars a blue ocean (from space) and a blue sky! Mars turns blue before we can then turn it into a garden. KSR simply named his books wrong! Red, BLUE, then Green is the framework used by the documentary below. (HD).
