If only we were a few decades ahead in our space tech, then we could
make sure the comet hits mars at a low angle for high ablation and
begin our terraforming efforts! The gases from a 50 km comet will be
substantial! Not to mention the heat/energy from impact could help
raise temperature, which would turn Mar's dry ice into even more
atmosphere; a nice chain reaction.
