    See How Much of NYC Will Be Under Water In 200 Years

    It's easy to laugh off the image of an underwater New York City when it comes from something like the humorous maps made by designer Jeffrey Linn that show neighborhoods like Bed Sea, Middrown, and Port Greene. But it's not so easy to laugh off when the image comes from climate change scientists. New data published in Science shows that if the planet warms by 2 degrees Celsius, sea levels will rise about 20 feet. It's pretty much a given that this will happen, it's just a matter of when—it could be by the end of the century. A 20-foot rise is no where near Linn's extreme depiction of a 100-foot rise, but it would still radically alter our coastline. The group Climate Central created an interactive map (h/t Gizmodo) that shows what this would mean for major cities in the United States. In New York, it means that entire neighborhoods would be wiped out and 1.8 million people would be displaced.

    All of Rockaway and Coney Island will be toast.

    Obviously, it's impossible to pinpoint when exactly this could happen, but according to Gizmodo, "scientists are modeling two different warming scenarios to help humans plot a roadmap for how to avoid these futures." In one model, the planet could warm by 2 degrees Celsius within a century—and with people living to be 116 friggin' years old, that means kids today would experience this—but Climate Central notes that two centuries is more likely:

    When could the sea fully reach this height? Perhaps sooner than 200 years from now (see Table 1 in this scientific paper), or perhaps much longer (for example, see this paper). It is easier to estimate how much ice will eventually melt from a certain amount of warming, than how quickly it will melt, which involves more unknowns.

    But hey, at least we can take comfort in the fact that our entire city won't be swallowed up by a massive earthquake and tsunami at any moment.

    That island on the right that will partially survive? It is made of trash.

    Roosevelt Island and Long Island City will be completely submerged.

    City Hall will be on its own island, while the World Trade Center will be under water.

    North Brooklyn will turn into an archipelago of sorts.
