How much land would be left woud be determined by how much global warming took place.
Melting ice caps would raise ocean levels but not by much 20-80 feet maybe.
Serious flooding would take place due to thermal exansion. Hotter water takes up more space than cooler water. The extent of thermal expansion would depend on how hot the climate had become.
A hotter climate with more water in the atmosphere would mean much more severe thunder strorms tornados and hurricanes. These too, would cause massive flooding.

Most of it would still be left (most of the middle of america...how ironic). Low lying areas would flood or become flooded with every storm surge. That would include alot of the coastal areas, (most of manhattan and brooklyn and staten island). There are a number of islands off the coast of bangladesh and eastern england that over the past 20 years have disappeared and the waters continue to rise, putting large parts of those countries at risk. In terms of other places like countries in europe, the Netherlands and italy would have huge problems since they're already very low and fighting storm surges all the time. I know that Bangladesh will mostly disappear since they can't afford to build so many hundreds of miles of levees and are the most at risk. Thus, that will probably be the biggest humanitarian crisis we have known as modern man. If you're thinking about global warming's effect as a whole, alot more people will die as a result of the mosquito/malaria line moving up to higher elevations and finally getting to very sensitive populations in africa and asia.

Well think of this, the icebergs in the ocean are kind of like icecubes in a glass of water they rise it but when it melts it stays the same. But some of the smaller islands and alaska and places would definately be gone because they have alot of ice on the surface which is what we need to worry about.

Find the 200 ft (60 m contour line on any topographical map. Everything now seaward of that would be submerged. Additional subsidence of land due to the added weight of the water might alter shorelines even more.

Almost all of it. If all the ice in the world were to melt, it would only raise sea levels by less than 200 feet.
