Before someone reading this thinks that drying up the planet would cool it down: water in the air acts as a greenhouse gas, but also cools the surface when it evaporates and helps reflect solar radiation when it forms clouds (major factor of our planet's albedo). Also we are not comparing more water area vs less water area. Water will take more area in any case as sea levels rise. This way it just happens in a bit more controlled way.
