The ocean rise could also be very sudden (if an antarctic or greenland ice sheet slides into the ocean) resulting in mass deaths in low lying areas like the Maldives and Burma.
Would there even be much of a rise, if any at all? Not only are the oceans extremely vast, but 90% of polar ice is underwater and already displacing ocean. Ice is more volumnous than liquid water, so if it should melt, it's possible that the oceans might even recede slightly.
Even so, I'm still not convinced that man will have had much impact on a temperature shift, should it come to be. There's a lot of informal evidence that during the time of the vikings, Greenland was indeed green, and Iceland was indeed ice. In addition, Roman accounts of the terrain in North Africa seem to indicate that it was much more moist than it is today. Yet there's not much of an indication that any cities were swallowed, or on the ither hand that the oceans receded much over the past 3000 years. The press definitely has an agenda to spread the rumor that global warming is not only a problem but is a man-made armageddon, if only to villify industry and everything that is non-cosmopolitan. I'm inclined to believe that most of it is hype, and like you said, global warming might end up making things better for almost everyone.
