Recently, scientists discovered that the albedo of the Greenland decreased by 5%

Perhaps this is due to the subsidence of the Arctic ice anthropogenic dust.

"Dr. Box estimates that darkening of the ice sheet in the 12 summers between 2000 and 2011 would have allowed the ice sheet to absorb an extra 172 quintillion joules of energy, nearly 2 times the annual energy consumption of the United States (about 94 quintillion joules in 2009). In areas where the ice sheet is melting, this additional energy has doubled melt rates, which contributes ice loss to the ocean and sea level rise. In non-melting areas, this extra energy would be enough to raise the temperature of a 5.5-inch-deep layer of snow from 14 degrees Fahrenheit (-10 Celsius) to the melting point."


The same can accelerate the melting of sea ice in summer. In a world of increasing the amount of coal burned.

"...return to a traditional diet..."

It's my understanding that it's never been completely abandoned. True, modern processed foods are imported in quantity into the Arctic, but the last I heard, 'country food' continues to make up very significant proportions of the diets of Canada's First Nations, including the Inuit. (As in, last I heard--admittedly a while back!--up to 50%.)

For one thing, there is considerable effort and interest in conserving cultural heritages, including foodways, and for another, Southern products tend to be very, very expensive.

traditional diet?

I recall watching a doco about Iceland. They have a whale hunting concession. And they make a big deal of eating the meat. But ......

They've had to limit the intake, especially for children and women. The load of toxic metals is too much for healthy development of foetuses and young children.

I wouldn't put too much reliance on the "Inuit diet made cancer and coronary diseases practically non-existent" claim.
With a life expectancy after age 4 of about 45, lots of deaths due to "accidents", and negligible medical resources for diagnosis the claim has a very poor data basis.

No tooth decay, yes. But how often did people with chronic conditions die due to accidents/exhaustion in bad weather?

It is very sad that the poles are the recipients of the mercury emitted by our power stations, and of other vaporised substances such as DDT.

thank you Neven! there is some stuff i didn't know. thank you for the links for more information. It seems like no place on earth is perfectly clean
