The climate crisis is causing unprecedented levels of stress and anxiety to people in Greenland who are struggling to reconcile the traumatic impact of global heating with their traditional way of life.

The first ever national survey examining the human impact of the climate emergency, revealed in the Guardian on Monday, shows that more than 90% of islanders interviewed fully accept that the climate crisis is happening, with a further 76% claiming to have personally experienced global heating in their daily lives, from coping with dangerous sea ice journeys to having sled dogs euthanised for economic reasons tied to shorter winters.

The Greenlandic Perspectives Survey was carried out by the University of Copenhagen’s Center for Social Data Science, the Kraks Fond Institute for Urban Economic Research and the University of Greenland. The study samples almost 2% of the population, spanning an area almost three times the size of France. An equivalent study in the UK would involve a sample of almost 1 million citizens.

Scattered across 17 small towns and approximately 60 villages, all situated on a narrow coastal strip, Greenland’s residents have often been overlooked by data science. The island faces some of the most acute social issues in the world with high levels of alcoholism and historically disproportionate rates of suicide.

According to its lead author, Kelton Minor, the survey finally gives Greenland’s most remote and inaccessible communities a voice on the climate crisis.

He said: “The Arctic is a bellwether for the unequal impact of global warming on social and economic systems. As countries struggle to limit future risks and overall warming to 1.5C [an increase of 2.7F], many Arctic and Greenlandic residents are already living in regional climates that have changed by more than this, in less than a lifetime.

“Therein lies the paradox: while satellites and sensors monitor the surface of Greenland’s ice sheet, chase icebergs and scan sea ice daily, relatively little is known about what the residents of Greenland think about their changing surroundings.”

Profile Greenland Show About 80% of the world's largest island is covered in ice. Inuit people first inhabited it by moving from present-day Canada 4,000-5,000 years ago. It was named by Erik the Red when he led a fleet of 25 ships from Iceland to colonise it in 985 AD. Population: 56,000 - 90% of whom live in 16 towns. Size: 836,000 sq miles (2.16m sq km) - roughly the same size as Great Britain, France, Germany, Spain, Italy, Austria, Switzerland and Belgium combined. Official language: Greenlandic - closely related to languages spoken by Inuit in Canada and Alaska.

National dish: Meat soup called suaasat which normally contains seal, whale, reindeer or seabirds.

Life expectancy: 72.9 years

Head of state: Queen Margrethe II of Denmark

Premier: Kim Kielsen

Capital city: Nuuk (population 18,000)

National anthem: Nunarput Utoqqarsuanngoravit, adopted in 1916. The first verse translates as: “Our country, which has become so old, your head is all covered with white hair. Always held us, your children, in your bosom, and gave us the riches of your coasts.”

Religion: Christianity was introduced to the island around 1000 by Erik the Red’s son Leif Eriksson.

Government: Denmark granted the island limited self-government in 1979, 26 years after it was incorporated into the country by the Danish constitution. Further powers were devolved in 2008. Economic self-sufficiency has been a stumbling block to the island gaining full independence.

EU membership: Greenland was a member of the European Union as part of Denmark from 1973 to 1985. It withdrew in 1985 after 53% of people voted to leave in a referendum called following disputes over fishing rights.

Military: There is no military force. Defence and foreign policy remain in the hands of the Danes.

Airports: 14. The first three were built in the 1940s and 50s by the US, which was handed the defence and control of Greenland while Denmark was under Nazi occupation.

According to the data, detailed in a Guardian investigation carried out across Greenland in the last month, the majority of local residents interviewed believe that the climate emergency will harm its people, sled dogs, plants and animals. The revelation contradicts arguments that local people believe climate breakdown will benefit the Arctic and raises concern over a growing mental health crisis around climate in the polar region.

Minor said: “We find that a large majority of the Greenlandic population thinks that local sea ice has become more dangerous to travel on in recent years, suggesting that perceptions of growing risk are widespread for this important social, ecological and economic platform used by residents from all regions. Importantly, we find that residents are more likely to feel negative rather than positive sentiment when thinking about climate change, recent changes in sea ice, as well as glacial changes.”

The survey is revealed as the Arctic faces potentially record warming levels. According to the National Snow and Ice Data Center in Colorado, US, Greenland has already lost more than 250bn tonnes from a combination of melt runoff and low total snowfall in July.

For mental health professionals who specialise in the polar region, the latest survey findings from Greenland will present another red flag for the Arctic’s vulnerable Inuit communities. According to Courtney Howard, the board president of the Canadian Association of Physicians for the Environment, who lives and works in the Arctic, the intersection between the climate emergency and mental and physical health will become one of the world’s major issues.

Howard said: “Temperature change is magnified in circumpolar regions. There is no question Arctic people are now showing symptoms of anxiety, ‘ecological grief’ and even post-traumatic stress related to the effects of climate change.

“We are challenging the medical profession to acknowledge the world we are inheriting. Schools and universities aren’t considering how climate change will affect people, from a medical or a psychological perspective, so we are not training a new generation of medical professionals to help people in a fast-changing planet and this is intolerable. We are moving too slowly on this.”
