What kind of impact could global warming have on the Caribbean?

Citizens in parts of Grenada are already pulling back from beachfront homes as the water rises and storms become more deadly. The Intergovernmental Panel on Climate Change said the economic hit from Hurricane Ivan, which damaged 90 percent of the homes, was twice the nation’s gross domestic product. Scientists and government officials worry about what’s next. United Nations’ models show that the 110,000 people across the Caribbean could be displaced, some 150 multimillion-dollar tourist resorts lost and 21 of 64 regional airports inundated by 2100.
