That's the one point where you're wrong: Land masses will actually shrink a little bit. Despite the heat making more evaporation of water [shrinking of lakes, desertification, etc.], the extra heat will balance this out by melting the polar ice caps. The ice caps are currently shrinking; if this accelerates the sea could rise 100-200 feet, putting a lot of the world's major cities underwater.
New York, Tokyo, Sydney, LA ... basically anything on the coastline? Gone.
