New DNA analysis reveals that, before their mysterious disappearance, the Norse colonies of Greenland had a “near monopoly” on Europe’s walrus ivory supply. An overreliance on this trade may have contributed to Norse Greenland’s collapse when the medieval market declined.
New analysis of the effects of melting permafrost in the Arctic points to $43 trillion in extra economic damage by the end of the next century, on top of the more than the $300 trillion economic damage already predicted.
Millennia-old genetic variant that once provided advantages for survival in cold climates increases risk of hypoglycemia and infant mortality.
New digital resource brings together centuries of cultural knowledge for the first time, showing that networks of trails over snow and sea ice, seemingly unconnected to the untrained eye, in fact span a continent – and that the Inuit have long-occupied one of the most resource-rich and contested areas on the planet.
The 24 July news story about the potential cost of Arctic methane release has provoked widespread coverage, including a critique in the Washington Post. Here, Professor Peter Wadhams responds to some of the comments that were made.
Economic modelling shows that the possible methane emissions caused by shrinking sea ice from just one area of the Arctic could come with a global price tag of 60 trillion dollars - the size of the world economy in 2012.
In 2010, researcher Stephen Leonard began a 12-month research project, documenting the disappearing oral traditions of the northernmost settled people on Earth. Now a short film about his experiences living with the Inugguit, whose way of life is threatened by climate change, is being released online.
Having just returned from a year spent documenting the language and culture of the remote Inughuit community of north-western Greenland, Dr Stephen Leonard describes how he witnessed first-hand the manner in which globalisation and consumerism are conspiring to destroy centuries-old cultures and traditions.
