Answer 1

Google relief maps. There are lots of sites.

Answer 2

The site Google earth will give you the elevation of any point you place the cursor on. It doesn't, however, show gradient lines if that is what you need to print out. Use the keywords "Relief maps" in your search engine, even try adding a general location after the word maps, such as "Gulf coast U.S.", or "Southern Florida,". You SHOULD look at not only HOW MUCH the rise in sea-level will encompas, but WHERE those rises will have the most effect. Our nations capital, and much of the eastern seabord's major cities will be inundated. Think of the synergistic effects that the loss of manufacturing, transportation, food production, and economic management caused in that reigon alone will cause, then look at how things will affect the gulf coast and the mississippi river valley. Remember, you aren't talking a mere 10 LINEAR feet back from current tide-lines, but 10 VERTICAL feet, and you have to allow for tidal effects, wave action, storm surges, etc.
