If the Falcon Heavy can send 14,000 kilograms to Mars [1]. How much warmer could 14,000 kilograms of this gas make mars? Anyone able to calculate?
14,000 kg would be equal to 98,000 tonnes of CO2. Trivial amount of heating, esp. since atmospheric forcing is weaker on Mars since the Sun is further away.
I reread it a year or two back, and it's standing the test of time very well, in spite of the fact that Red Mars was first published almost 21 years ago and the story begins in the 2020s.
As ealloc points out [2], this particular fluorine compound isn't very different, as a greenhouse gas, from the other CFCs these estimates are based on.
