Global sea levels are rising and the world’s land ice is disappearing. Sea levels have risen 6 to 8 inches in the past 100 years, and Antarctica has been losing more than 100 cubic kilometers of ice per year since 2002, according to NASA satellite data.
By the year 2100, the Intergovernmental Panel on Climate Change estimates that sea levels will rise as much as 20 inches.
While rising sea levels ultimately influence the entire planet, they pose the greatest threat to the islands currently residing at sea level.
Here are some of the islands — many of them small nations — likely to face this crisis first.
