The world may not often be very interested in Greenland but it is fascinated by what lies beneath it. As the country’s ice cap melts, hidden mineral wealth is coming tantalisingly within reach. The country’s riches include “rare earth” metals that are essential in the production of many electronic devices, from electric-car batteries to television screens. Metals such as cerium (used in glass manufacturing) and yttrium (which goes into electronic displays) are among those that are hidden under the ice. Many rare earths are not as scarce as their misleading name suggests, but they are scattered thinly and can be difficult to extract. In Greenland they are often mixed up with uranium, which under the country's current laws is illegal to mine. Most of the precious metals therefore remain underground. ...Should Ms Hammond’s plans go ahead, and Greenland manage to ramp up its extraction of rare earths, it could deliver a jolt to the market for the valuable metals. At the moment rare-earth supply is dominated by China. In recent years China has restricted its exports of rare earths, citing environmental concerns. Extraction of the metals is dirty and dangerous, and stories of poisoning are common. But some see an ulterior motive in China’s cutbacks: by controlling the supply of high-value materials, China can also control their use in finished products. That could help it in its broader strategy to move from low- to high-value manufacturing. If Greenland becomes a big supplier of those same minerals, China’s grip on the market could loosen, and prices around the world may fall. Polar politics therefore matter to many more than the 57,000 people who live in 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 been halved to 1,500 in just a decade. Suicides are up.
“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 — perhaps nowhere 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 may someday even render it the first sovereign nation created by global warming.
“One of our goals is to obtain independence,” said Vittus Qujaukitsoq, a prominent labor union leader.
But the rapid transition from a society of individual fishermen and hunters to an economy supported by corporate mining raises difficult questions. How would Greenland’s insular settlements tolerate an influx of thousands of Polish or Chinese construction workers, as has been proposed? Will mining despoil a natural environment essential to Greenland’s national identity — the whales and seals, the silent icy fjords, and mythic polar bears? Can fishermen reinvent themselves as miners?
“I think mining will be the future, but this is a difficult phase,” said Jens B. Frederiksen, Greenland’s housing and infrastructure minister and a deputy premier. “It’s a plan that not everyone wants. It’s about traditions, the freedom of a boat, family professions.”
The Arctic is warming even faster than other parts of the planet, and the rapidly melting ice is causing alarm among scientists about sea-level rise. In northeastern Greenland, average yearly temperature have risen 4.5 degrees in the past 15 years, and scientists predict the area could warm by 14 to 21 degrees by the end of the century.
Energy companies should not drill for crude oil in Arctic waters because the environmental risks are too high, Total SA Chief Executive Officer Christophe de Margerie said in the Financial Times on Wednesday. The newspaper described de Margerie's comments as the first time a major oil company has publicly criticised offshore exploration in the Arctic.The risk of an oil spill in such an environmentally sensitive area was simply too high, according to de Margerie. "Oil on Greenland would be a disaster. A leak would do too much damage to the image of the company," he said.

New research on the dynamics of Greenland’s ice sheets complicates efforts to forecast sea level rise in this century, as the Green Blog reports. Expanding fields of crevasses appear to be limiting the flow of water to the base of the ice through tube-like moulins. That flow has been thought to ease the seaward movement of the ice over bedrock. But the crevasses also warm the ice as liquid water descends deep inside the frozen mass, with that process also potentially speeding its flow. This diagram shows the two types of plumbing.
In the meantime, the high recent rate of ice loss in Greenland, according to other new research, has largely continued.
