      1. I'm at 548 feet above current sea level.

      I won't shut up and I don't waste my time teaching pigs to sing

      2. Well, finally! A solution to Florida.

          Don't blame me. I voted for Bernie and Jill.

        4. And most of the major population centers of the East coast, much of the West

        coast and the Gulf. Check out Europe too.

          5. I've been looking forward to beachfront property.

          I’m at about 1800 feet.

          20. The East Coast will be hit harder then the West Coast

          The main reason is Continental Drift.  The North American Plate is being driven westward over the Pacific Plate.  This is causing the Mountains in the West to grow taller and with it the land to those Mountains WEST (The West Coast).  Do to this the West Coast rise quite rapidly in height starting with at the coasts.  The West Coast Beaches are rarer and smaller then beaches on the East and Gulf of Mexico for that reason.

          The two big concerns in the West is the Central Valley of California, for it was formed as a dip between the coast and its increasing height and the Sierra Madras and their increasing heights.   Given the gap in the Coastal ridge that is the Entrance to San Francisco Bay, the whole central valley is subject to becoming ocean.  This is mostly if and when the East Antarctic Ice Sheet (EAIS) melts and will be the product of decades of excessive heat.

          The second problem area is the Gulf of California and the Salton Sea.  Like the Central Valley, it is a dip between the coast and the Mountains, but the Gulf of California is within that dip.  Right conditions, right circumstances, you can see a surge of from West Antarctica driving north along the Coastline and being caught in the Gulf of California and the water, having no place else to go driving right across the US-Mexican Border and right to the Salton Sea, moving enough dirt to make the Salton Sea the new northern part of the Gulf of California.  This can occur with the collapse of the West Antarctica Ice Sheet (WAIS) which an collapse over night increasing world wide sea levels by 7 meter or 20 feet within days as oppose to decades.

          On the other hand the East Coast and the Coast along the Gulf of Mexico are the product of the gradual movement of the North American Continent Westward.  No over growth of one plate over another, but the result of the slow push caused by the rift in the middle of the Atlantic Ocean (Iceland is the northern part of that rift).   This permitted the development of long gradual shorelines that is typical of the Eastern US.

            21. Wow! Thanks for the info! I always wondered why the East Coast

            was in more danger. Ugh!

        6. Giggle!

        Miami is already building a flood wall but it will only be good for ten years.

          9. I thought that was pointless since they are built on limestone and the water wil

          just bubble up through the ground?

            13. ScarlettO'Hara urban planning-Fiddle-di-di;we'll worry about that tomorrow!

            You are absolutely right.  All of South Florida, including Miami, has a porous limestone base (hence all those pesky sinkholes).  High tides  and bi-annual “King Tides” have been damaging cars and lawns and negatively affecting businesses for years.  Now scientists raise concerns that these  waters are also a major health hazard.This article from November, 2016.

            King-Tide Floodwater in Miami Beach Might Be Full of Human Waste
            Tuesday, November 15, 2016 at 8:30 a.m.

            “Whatever you do, don’t come into contact with the floodwaters,” says Florida International University hydrologist Henry Briceño, who participated in a National Oceanic and Atmospheric Administration (NOAA) study on water pumped from the city’s streets and back into Biscayne Bay.

            Briceño’s study, which was published in February, showed unacceptably high levels of human waste in the floodwaters being pumped back into the bay by a $400 million anti-flooding system that’s still being installed around Miami Beach. NOAA’s researchers found highly elevated levels of nutrients, hydrocarbons, and bacteria in the untreated storm water; those pollutants can lead to algae blooms and kill marine life.

            Are those same pollutants swimming around in the storm water sitting on city streets this week? Briceño suspects they are.

            “What happens is that the soil under Miami is very porous and the sewer system is not very good, so any kind of pollutant goes into this lens of fresh water that floats atop the salt water. When the tides rise, that dirty fresh water comes up and fills the streets,” he says.

        7. How useful and interesting to know that drowning people would cheer you up!

        You think the only reason that people won't vote for a warmongering Third Way fracking-enabling cluster bomb throwing H-1B increasing lying pandering corporate and Wall Street shill who says she has no problem putting abortion rights on the table is because we are mad about Bernie?  Um, nope.

          10. so unlike you

          any way you look at Global warming, we are going to lose people, heck we will probably be dead by then, Now according to their chart, my house will be underwater in 2050. Will I be Alive? probably not, will I have sold it by then,  I hope so!!!!!!

            11. It is the casual dismissal of an entire state that brought that on.

            Like, for instance, saying Nevada is nothing but a bunch of gamblers and prostitutes.  Or everyone in Maine is pretty much accurately portrayed as the family in The Beans of Egypt, Maine.  (good book, BTW.)  I am a Floridian and I don’t engage in weird/illegal/gun-related/drug-induced acts at all.  Anyways, I have provided for my family by buying a five acre lot in the middle of Nowhere, Texas.  If nothing else, they can pitch tents and catch rabbits or whatever runs around in the scrub.  With my unerring eye for profitable real estate, I managed to nab five acres that has never been worth more than the $2000 I paid for it over ten years ago!

            Here’s a bright spot in all of this –

              14. Mother Nature will be dismissing the entire state but they

              are still building high-rise condos in Miami.

                15. Sort of like how the real estate people had a law passed so that no regulations

                could be based on global warming in North Carolina.  Can’t threaten real estate values until they are sure they will be bailed out.

                http://wunc.org/post/state-outlawed-climate-change-accepts-latest-sea-level-rise-report#stream/0

                Five years ago, the Science Panel of the North Carolina Coastal Resources Commissioner presented a report that outlined the possibility that sea levels along the coast could rise as much as 39 inches over the next 100 years. Reaction from local land managers and developers was quick and overwhelmingly negative. The General Assembly passed a law forbidding communities from using the report to pass new rules.

              18. oh yeah, your acres in Texas.

              I once refused to buy land in NC because I would only see it once a year, big mistake I could have made a bundle if I held on to it for one year, then lost my shirt if I held onto it for 10. No, I would still have profited, just not very much.

          17. That did not come out right. sorry.

          The giggle was for the solution to Florida comment.  I am sorry.  I do not want people to drown.  I hope most people will get out in the next few years.

      3. Good tool. Don't forget to sdd another thirty feet or more for storm surges

      which will get worse.

      12. I have beachfront property

      Not now, but when all the polar ice caps melt.

      How soon should I start building a dock on the creek behind the property?

      19. Here is a web map, where you can vary the increase, both world wide and local

      http://geology.com/sea-level-rise/

       

      You map shows the world if and when the East Antarctic Ice Sheet melts.   70% of all FRESH WATER is in that Sheet.  The East Antarctic Ice Sheet is also the Continent with the TALLEST average elevation (Asia’s Himalayas are offset by the low lands of Siberia, India and Southeast Asia, the same with South America, the Andes are offset by the Lowlands on the Atlantic Side of South America and North America Rockies are off set by the low lying middle of the Continent, the Mississippi River BOTTOM is already at sea level as it crosses the Missouri-Arkansas State line).  Thus, on average the East Antarctic Ice Sheet (EAIS) is on the TALLEST continent in the World.  The  East Antarctic Ice Sheet (EAIS) is also entirely within the Antarctic Circle and has little connection with the Ocean that surrounds Antarctica.

      Now the WEST Antarctic Ice Sheet (WAIS) is another story.  The WEST Antarctic Ice Sheet (WAIS)  is grounded BELOW SEA LEVEL so it interacts with the surrounding ocean, and that Ocean’s growing warmth  The WEST Antarctic Ice Sheet (WAIS) is considered inherently unstable given it being grounded below sea level, through it only contains about 10% of total fresh water (if the WEST Antarctic Ice Sheet (WAIS) ever breaks, it can raise world wide sea level  about 20 feet, or about 7 meters).   The down side is the West Antarctic Ice Sheet (WAIS) can do this almost overnight, i.e. break up some March or early April day, the time the Summer in the Antarctic is over and the West Antarctic Ice Sheet (WAIS) is at its weakest.  The West Antarctic Ice Sheet (WAIS) has been called the Godzilla of Global Warming, no gradual increase, a sudden almost overnight increase in sea level by 15 to 20 feet.

      Now, your maps shows what happens when the East Antarctic Ice Sheet (EAIS) melts.  Unlike the West Antarctic Ice Sheet (WAIS), the East Antarctic Ice Sheet (EAIS) is actually expected to EXPAND do to global warming over the next couple of decades.  Warmer air will carry more water over the East Antarctic Ice Sheet (EAIS) and fall as snow and then turn to Ice.  Then sometime after 2040, if not later,  the East Antarctic Ice Sheet (EAIS) will start to melt and sometime after 2100 we can expect what your map points out.   Unlike the WEST  Antarctic Ice Sheet (WAIS) the East Antarctic Ice Sheet (EAIS) is only expected to melt not collapse, thus the increase in sea level height will be gradual, over decades.  There are parts of the East Antarctic Ice Sheet (EAIS) that can collapse overnight but any collapse will NOT be close to what the West Antarctic Ice Sheet (WAIS) can do when it comes to world wide sea levels.

      The Above map starts at  7 meter, or about 20 feet. That is what a collapse of the West Antarctic Ice Sheet (WAIS) can do, it goes to 60 Meters, which is what world sea level will be when the East Antarctic Ice Sheet (EAIS) melts  (The West Antarctic Ice Sheet (WAIS) and the Greenland Ice Sheet will both be gone long before then, both hold about the same amount of water, about  7 meters, or 20 feet worth).   The Greenland Ice Sheet expends south of the Arctic Circle and thus subject to greater heating then the other two Ice Sheets, thus will melt quicker then either but NOT subject to any sudden Collapse.   The other Ice Sheets, the Glaciers around the world, contain very little water when compared to the three Big Ice Sheets, the East Antarctic Ice Sheet (EAIS), the West Antarctic Ice Sheet (WAIS) and the Greenland Ice Sheet.  All together, the lakes, rivers and Glaciers of the world contains less then 10% of all of the fresh water and most of that is in lakes and rivers NOT Glaciers.

      Just want to clarify what the fear should be when it comes to increase in world wide sea level do to global warming so that you are NOT faced with someone who pints out the expansion of the East Antarctic Ice Sheet (EAIS) as showing Global Warming is NOT occurring, that expansion is within the programs showing what Global Warming will do to this planet.
