![]() “The brutality of nature used to bring joy, but now it scares people,” says Holmen. “We identified ourselves as people who could ‘stand the storm.’”īut that confidence has been replaced by anxiety. In Longyearbyen’s case, the avalanches “have changed the mood in the village quite dramatically,” says Holmen. Assumptions that present day climate change “is not so serious,” have been proven wrong, he says, adding that the increasing strength and frequency of extreme events “needs attention.” Kim Holmen, of the Norwegian Polar Institute, says that Longyearbyen’s story is a “forewarning” for other parts of the world. He says it is vital to reduce manmad-e greenhouse gas emissions to prevent carbon release from happening. “Permafrost holds an immense amount of carbon – enough to double the amount of carbon dioxide in the atmosphere” says Frans-Jan Parmentier, an Arctic climate scientist who conducts research at a station just outside Longyearbyen. Perhaps most worrying of all, the thawing permafrost could fuel further global warming. “But now, because the ice disconnection occurs earlier and lasts longer, the bears run into food shortages.”Īccording to the new report, the average temperature in Longyearbyen is predicted to rise by 7☌ to 10☌, and rainfall by 40% to 65%, by the end of the century, depending on the level of global carbon emissions. Unable to hunt for ring seals on the ice floes, in the past the bears would eke out the warmer months by raiding eggs on the cliffs. “If the bears miss the ride, they are stranded on the shore for the summer.” “The floating sea ice disconnects from the land in the summer,” explains Holmen. When rain freezes and forms ice, Svalbard's reindeer are at risk of starvation. The reindeer are unable to break through the ice to reach the grass below. “When the water hits the ground, it freezes,” he says. But snow is increasingly giving way to rain. “During winter, reindeer stomp the ground with their front legs to get the snow away in order to graze,” he says. Land-bound animals cannot relocate and starving reindeer are now a common sight, says Holmen. Atlantic cod have arrived in their place, swimming north to the warming waters, says Holmen. Polar cod, which used to swim in the fjord, have disappeared along with the ice on which they depend. Speaking in February, he said: “At this time of year, we used to have a meter of ice on the fjord, I could see from my window. Kim Holmen, international director of the Norwegian Polar Institute and a resident of Longyearbyen, has been observing the former coal mining town’s changing landscape for over three decades. ‘Doomsday Vault’ Protects Earth’s Food SupplyHere’s How Designed to be insulated from a cataclysm, the Svalbard Global Seed Vault sprang a leak last year. ![]() Pipes containing a coolant were threaded through the soil, and a freezing mat laid on top of the tunnel to help the permafrost stay frozen. Statsbygg also transferred heat-producing electrical equipment from inside the tunnel to a separate facility and dug ditches to divert meltwater. Since its inception, except in the case of urgent deposits, the vault’s doors are opened just three times a year the rest of the time the vault is. ![]() “We replaced the steel entrance tunnel with a waterproof concrete tunnel,” says Aschim. With a total capacity of 4.5 million samples, the so-called Doomsday Vault serves a humanitarian purpose in providing a last-resort Noah’s ark for the planet’s seeds. Statsbygg undertook 100 million Norwegian krone ($11.7 million) of reconstruction work, more than double the original cost of the structure. Labels indicating the depositor are stuck on the boxes containing packages and then the information about where the package is stored is entered into the NordGen data base.Construction work on the seed vault's new service building and tunnel entrance. Each package can hold about 500 seeds of one variety. The seeds are dried in advance and packed in special aluminum packages measuring 60х40х28 centimeters, so the depositary shelves can accommodate them all. Seeds are accepted approximately three times a year and are delivered by aircraft or ship. ![]() ![]() Not all seeds are accepted for storage but only those which are important for plant growing, agribusiness and scientific studies, for example, wheat, rice and barley.

The building is divided into three rooms, each of which can store 1.5 million seeds. It is important to note that the seeds at the depositary remain the property of the country of origin or genetic material bank which gave them over for storage. Over 320,000 seeds were put into the bank at the opening ceremony. ![]()
