President Anote Tong today ended a Greenpeace-organized tour of glaciers in Norway's Svalbard Archipelago, a trip he said left a deep impression that he would share with world leaders at a UN climate summit next week in New York.
"It's a very fascinating sight. In spite of that, what I feel very deeply is the sense of threat," Tong said. "If all of that ice would disappear it would end up eroding our shores."
In a landmark report last year, the UN's expert panel on climate change said oceans could rise by as much as 1 meter (3.3 feet) by the end of this century if no action is taken to cut the greenhouse gas emissions blamed for global warming.
The summit in New York is meant to build momentum for a global agreement next year to cut emissions.
Tong said he hopes his country won't have to be evacuated.
Still, it has bought 20 square kilometers of land in Fiji as "an investment, a guarantee" in case part of the population has to be moved, he said.
