Several new studies underscore scientists' concerns we're headed toward a coastline at least this [zie kaartje boven; K] flooded (20 meters or 69 feet) over many hundreds of years.

The worst-case scenario for sea level rise has now become simply the "business-as-usual" scenario, recent studies from NASA make clear. NASA glaciologist Eric Rignot, co-author of a new Greenland study, says that, taken together, the new papers "suggest that the globe's ice sheets will contribute far more to sea level rise than current projections show."

That means if we don't reverse carbon pollution emissions trends ASAP, sea level rise will likely be 4 to 5 feet or more by century's end. Also, the rate of sea level rise in 2100 could be upwards of 1 inch per YEAR! [...]
