Polar ice and permafrost sound an odd combination with tropical palm beaches and coral atolls but scientists say both the Arctic and small islands are among the most vulnerable to global warming, widely blamed on human use of fossil fuels.

"There are so many similarities between the two regions and we hope to ... see how collaboration can be made at community level," said Grete Hovelsrud, research director at the Center for International Climate and Environmental Research in Oslo.

Hovelsrud told Reuters the meeting of 40 delegates would be the first of its kind since a "Many Strong Voices" plan for Arctic peoples and island states was launched at UN talks in Montreal in 2005. Hovelsrud is a leader of the programme.

Both Arctic peoples and those in tropical islands depend on the coasts -- Inuit people rely on sea ice for hunts of polar bears or seals while many islands rely on fishing or tourism based on the lure of white sands, coral reefs and palm beaches.

"In the Arctic the ice is disappearing," she said. "In the tropics, rising seas are damaging beaches. And seawater is percolating into the ground water and damages crops."

The Arctic region and small island developing states account for just one percent of greenhouse gases. By teaming up they might raise their political clout.

"The Inuit don't have the front seat when it comes to policy making and I don't think the small islands do either," Hovelsrud said. The talks are partly sponsored by the United Nations and the Organisation of American States.

The talks would try to work out a five-year plan of work and examine possibilities for a broader study of threats to small islands modelled on a 2004 study of the Arctic by 250 experts.

A report by the UN climate panel in April said that small islands were "especially vulnerable to the effects of climate change, sea level rise and extreme events." Erosion of beaches or damage to corals could damage fisheries and tourism.
