Grist writes about the underestimated toll global warming will take on the United States in the near future, increasing the sea-level rise by amounts that will leave many devastated.

What the scientific community has failed to communicate, and the public has failed to grasp, is that the U.S. is particularly vulnerable to very small increments of sea-level rise.

The IPCC Fourth Assessment projects a sea-level rise of 0.18 meters to 0.59 meters this century. Even though the report includes a caveat that this range does not include any significant contribution from the Greenland and West Antarctica ice sheets, global warming skeptics continually characterize those who mention a six-meter sea-level rise as scaremongers.

There is also a common notion in circulation, advanced by the media and many studies on the impacts of climate change, that wealthier countries in the West will be able to adapt, while underdeveloped countries will bear the brunt of the impacts.
