What Does U.S. Look Like With 10 FEET OF SEA LEVEL RISE?
New research indicates that climate change has already triggered an unstoppable decay of the West Antarctic Ice Sheet. The projected decay will lead to at least 4 feet of accelerating global sea level rise within the next two-plus centuries, and at least 10 feet of rise in the end. What does the U.S. look like with an ocean that is 10 feet higher? The radically transformed map would lose 28,800 square miles of land, home today to 12.3 million people.These figures come from Climate Central research published in 2012, analyzing and mapping every coastal city, county and state in the lower 48 states. (A next generation of research is currently under way.)
More than half of the area of 40 large cities (population over 50,000) is less than 10 feet above the high tide line, from Virginia Beach and Miami (the largest affected), down to Hoboken, N.J. (smallest). Twenty-seven of the cities are in Florida, where one-third of all current housing sits below the critical line — including 85 percent in Miami-Dade and Broward counties. Each of these counties is more threatened than any whole state outside of Florida – and each sits on bedrock filled with holes, rendering defense by seawalls or levees almost impossible.
By the metric of most people living on land less than 10 ft above the high tide line, New York City is most threatened in the long run, with a low-lying population count of more than 700,000. Sixteen other cities, including New Orleans, La.; Norfolk, Va.; Stockton, Calif.; Boston, Mass.; St. Petersburg, Fla.; and Jacksonville, Fla.; are on the list of places with more than 100,000 people below the line. (Much of New Orleans is already below sea level, but is protected at today’s level by levees.)
Climate Central’s enhanced analysis paints a much more detailed pictured for completed states. For example, more than 32,000 miles of road and $950 billion of property currently sit on affected land in Florida. Threatened property in New York and New Jersey totals more than $300 billion. And New England states all face important risks. The predicted sea level rise will take a long time to unfold. The numbers listed here do not represent immediate or literal threats. Under any circumstances, coastal populations and economies will reshape themselves over time. But the new research on West Antarctic Ice Sheet decay — and the amount of humanity in the restless ocean’s way — point to unrelenting centuries of defense, retreat, and reimagination of life along our coasts.

but it's called science. Yeah, it's a lot of ice and it's all melting. And the oceans that exist currently are heating up. So what happens to objects as they heat up?
10 feet will take some time, but we've been hitting all the milestones faster then expected.
It will be a lot warmer too. 
making me a little cryptic.
OK, a lot cryptic.
happens more frequently, then becomes the other.

the first to respond to my comment.
It's also funny how you follow me around...and creepy.
Do you have a response that someone can actually use, you know, something with substance? After all, my comment was intended to draw out the reasons why we should care today about the sea level 200 years from now, not clueless 3-letter replies like: "WTF?"
Also, please link to a substantive post that was crafted by you. I'm just interested in knowing if you've ever said anything thoughtful or useful.
I submit here and now that you have never posted a single, meaningful, thought-provoking post during you entire tenure on DU.
" Totally substance free response, as usual..."
Much as "why should we care" also being one? Six of one, half a dozen of the other... 
(insert distinction without a difference here-- as it would look odd for you to indict others for the same guilt you hold)
