A Melting Greenland Weighs Perils Against Potential By ELISABETH ROSENTHAL October 08, 2012. NARSAQ, Greenland — As icebergs in the Kayak Harbor pop and hiss while melting away,this remote Arctic town and its culture are also disappearing in a changing climate.Narsaq’s largest employer, a shrimp factory, closed a few years ago after the crustaceans fled north to cooler water. Where once there were eight commercial fishing vessels, there is now one.As a result, the population here, one of southern Greenland’s major towns, has beenhalved to 1,500 in just a decade. Suicides are up.Andrew Testa for The New York Times.“Fishing is the heart of this town,” said Hans Kaspersen, 63, a fisherman. “Lots of people have lost their livelihoods.”But even as warming temperatures are upending traditional Greenlandic life, they are also offering up intriguing new opportunities for this state of 57,000 — perhapsnowhere more so than here in Narsaq.Vast new deposits of minerals and gems are being discovered as Greenland’s massive ice cap recedes, forming the basis of a potentially lucrative mining industry.One of the world’s largest deposits of rare earth metals — essential for manufacturing cellphones, wind turbines and electric cars —sits just outside Narsaq.This could be momentous for Greenland, which has long relied on half a billion dollars a year in welfare payments from Denmark, its parent state. Mining profits could help Greenland become economically self sufficient and render it the first sovereign nation created by global warming.“For me, I wouldn’t mind if the whole ice cap disappears,” said Ole Christiansen, the chief executive of NunamMinerals, Greenland’s largest homegrown mining company, as he picked his way along a proposed gold mining site up the fjord from Nuuk, Greenland’s capital. “As it melts, we’re seeing new places with very attractive geology.”The Black Angel lead and zinc mine, which closed in 1990, is applying to reopen this year, said Jorgen T. Hammeken-Holm, who oversees licensing at the country’s mining bureau, “because the ice is in retreat and you’re getting much more to explore.”The Greenlandic government hopes that mining will provide new revenue. In granting Greenland home rule in 2009, Denmark froze its annual subsidy, which is scheduledto be decreased further in the coming years.Here in Narsaq, a collection of brightly painted homes bordered by spectacular fjords,two foreign companies are applying to the government for permission to mine.“This is huge; we could be mining this for the next 100 years,” said Eric Sondergaard, a geologist with the Australian-owned company Greenland Minerals and Energy, whowas on the outskirts of Narsaq one day recently, picking at rocks on a moon-likeplateau rich with an estimated 10.5 million tons of rare earth ore.That proximity promises employment, and the company is already schooling some young men in drilling and in English, the international language of mine operations. It plans to build a processing plant, a new port and more roads. (Greenland currently has none outside of settled areas.) Narsaq’s tiny airport, previously threatened with closure from lack of traffic, could be expanded. A local landlord is contemplating converting an abandoned apartment block into a hotel.“There will be a lot of people coming from outside and that will be a big challenge since Greenlandic culture has been isolated,” said Jasper Schroder, a student home in Narsaq from university in Denmark.
