In one of the report's most worrisome findings, the agency estimates that in light of recent ice sheet melting, global sea level rise could be as much as four feet by 2100. The IPCC had projected a sea level rise of no more than 1.5 feet by that time, but satellite data over the past two years show the world's major ice sheets are melting much more rapidly than previously thought. The Antarctic and Greenland ice sheets are now losing an average of 48 cubic miles of ice a year, equivalent to twice the amount of ice that exists in the Alps.
A four foot change really means something to a number of the more famous (and less famous) coastal attractions in New Jersey like Cape May, Atlantic City, Wildwood, or Sandy Hook. But it also will severly impact the less visitable coastal wetlands that make some of these places possible. Even in New Brunswick and 4' rise would be a serious thing to consider, so I hope the county isn't spending any more tax money on a marina down there.
