New Interactive Map For Understanding Global Flood Risks

Posted by timothy on from the seek-out-higher-ground dept.

An anonymous reader writes "Using computations on the massive near-global SRTM surface model from NASA, this map lets you query watersheds, interactively set the sea-level and flood the world (North America at 500m increase in sea-level), or play around with river thresholds on a global or regional scale (computed rivers around NYC/NJ). It can be used to get an understanding of the watersheds and water flow paths in your local neighborhood; do you know where rain (or pollutants) that falls in your backyard end up? The map is freely available to the public."

    Why not go the whole hog and allow for a FALL in sea-level by enabling negative values? Surely we have the necessary sea-floor maps and people who think climate change is running the other way.

      Well, that would actually make more sense than the 500m that the link points to. If all ice in both the south pole and Greenland melts the sea-level will rise with about 80m. To get above 100m we will need to import water from another planet.
      The range that would be of interest would be somewhere between -100 to 100m for showing everything from a new ice age to an ice-free planet.
      I guess even lower than -100m is still theoretically possible. 500m is just retarded scaremongering that undermines their credibility.
