We've added the ability to flood the entire planet by blasting it with storms, or to turn it into a fiery inferno with massive solar radiation. Be aware that doing so will most likely kill off any plants or animals living on the planet. However, if your civilization is technologically advanced enough, they may be able to hold on long enough to see the disaster through. If you decide to relieve their suffering, that is.
