The far northern city of Kiruna usually meets winter on the 10th of October, and the northern coastal city of Umeå usually has winter weather by the 4th of November.
But instead of winter, fresh wild strawberries are still growing.
Alexandra Ohlsson at the Swedish Meteorological Institute (SMHI) says to news agency TT that winter will probably be at least another week away.
As well as ripening strawberries, the mild temperatures in the northern part of Sweden are also good for pests like mosquitoes and ticks.
Winter is officially defined as an average temperature of below zero for five days in a row. It usually reaches Stockholm by the 1st of December, Gothenburg by the 29th, and Malmö by the 7th of January.

Fast-melting Arctic sea ice appears to be pushing walruses to haul themselves out onto land, and many are moving around the area where oil leases have been sold, the U.S. Geological Survey reports.
Walruses are accomplished divers and frequently plunge hundreds of feet (meters) to the bottom of the continental shelf to feed. But they use sea ice as platforms to give birth, nurse their young and elude predators, and when sea ice is scarce or non-existent, as it has been this summer, they come up on land.
Last September, the loss of sea ice caused an estimated 10,000 to 20,000 walruses to venture onto land, and as sea ice melts reached a record last month, U.S. government scientists are working with Alaskan villagers to put radio transmitters on some of the hauled-out walruses to track their movements around the Chukchi Sea.
“The ice is very widely dispersed and there is little of it left over the continental shelf,” researcher Chad Jay of the U.S. Geological Survey said in a statement on Wednesday. “Based on our tracking data, the walruses appear to be spreading out and spending quite a bit of time looking for sea ice.”
The loss of sea ice puts Pacific walruses at risk, according to the U.S. Fish and Wildlife Service, but other, higher-priority species will get attention first. In February, the wildlife service listed Pacific walruses as candidates for protection, though not protection itself.
Walruses are protected under the Marine Mammal Protection Act, which means these animals cannot be harvested, imported, exported or be part of interstate commerce.
Polar bears, which also use sea ice in the Chukchi Sea as platforms for hunting, have been designated as threatened under the U.S. Endangered Species Act because of declining sea ice in the Arctic.
Compared to last year’s massive haul-out, there are few walruses on land, and there is no solid count, Jay said.
“There is a lot less ice than there used to be on the continental shelf this time of year,” he said. “So we might be headed into a new normal.”
Transmissions from the radio-tagged walruses offer a good picture of where these creatures are in the Chukchi Sea in a U.S. Geological Survey graphic updated approximately weekly.
SHRINKING ARCTIC SEA ICE
Available online here , the graphic shows where the walruses were when they were first tagged (shown as red Xs) and how they moved around the water (shown as yellow dots).
The graphic also shows changes in sea ice cover in the far north, indicating nearly ice-free conditions in areas where the walruses are moving. Many are within the boundaries of an oil lease sale area that stretches along the northwestern Alaska coast and far into the Chukchi Sea.
Royal Dutch Shell, ConocoPhillips and Statoil hold leases in the Chukchi Sea, though no drilling has started.
Last month saw Arctic sea ice drop to its lowest extent — meaning that it covered the smallest area — for any July since satellite records began in 1979, according to the U.S. National Snow and Ice Data Center. Typically, Arctic sea ice hits its lowest extent for the year in September.
This record-low ice extent for July is lower than July ice extent in 2007, when ice extent shrank in September to its smallest area in the satellite record.
Several persons were injured when a polar bear attacked people near the Von Post Glacier approximately 40 kilometers from Longyearbyen.
It has been a busy situation for ambulance personell at Longyearbyen, and assistance from the mainland was immediately sent northwards.
This article on nrk.no first broke the news of the incident which was reported to the Sysselmann at Spitsbergen around 07:30 AM today, August 5th. The polar bear is now dead and health personell have arrived on site, the Sysselmann reports.
“We have received four patients. All of them have moderate to serious injuries, mainly head injuries”, says Jon Mathisen, director of the department for acute medicine at the University Hospital in Tromsø to VG Nett.
Liv Ødegaard, information consultant with the Sysselmann office, tells NRK that they don’t have a complete overview of the situation so far, including how seriously hurt the persons involved are.
“We can now confirm that they were camping there, but if they were tourists or scientists is too early to say. At this stage we have made a priority of getting the injured persons medical help”, Ødegaard said earlier this morning.
None of the involved people are identified so far, and the British department of foreign affairs does not have an overview of the situation yet.
Starvation and lack of food is the most common motivation for a polar bear to attack people say Jon Aas, scientist at the Norwegian Polar Institute.
“All polar bears are potentially dangerous, but there are higher numbers of young and starving bears involved in attacks”, Aas says.
Kjersti Norås, tourism coordinator on Spitsbergen says that the Von Post Glacier is a common site for tourists to visit. “You can go there on snowmobiles in the winter to get to Pyramiden”, she informs VG Nett.
It is recommended to carry guns when out in the field on Spitsbergen, and the company who met the bear have killed the animal themselves.
Since 1971, four people have been hurt and four people killed by polar bears on Spitsbergen, Margrete Nilsdatter Skaktavl Keyser states in her master thesis on the subject.
When situations with polar bears arise, the only solution is to kill the animal if possible, or else get killed.
We should now ask ourselves: Is tourism on Spitsbergen OK? Perhaps travelling in these areas should be restricted to personell with real business in the area? Useful activities like science, hunting and industry? Perhaps we should keep tourists and adventurers off these pristine nature reserves?

Analysis of subtle chemical variations in reindeer teeth suggest the Neanderthal employed sophisticated hunting strategies similar to the tactics used much later by modern humans. Kate Britton, an archaeologist now at the University of Aberdeen, and her colleagues wanted to find out more about adult reindeer remains from a 70,000 year old layer at the Jonzac Neanderthal hunting camp site in France – a rock shelter believed to have been used over a long period of time – by looking at the teeth and their chemical composition.
Teeth are made of calcium, phosphorus, oxygen, strontium and other elements, but not all the atoms of each element are the same. Some atoms, or isotopes, are heavier than others and may have slightly different chemical properties. Says Britton, “Strontium in your bones and teeth is related to the food and water you consume… to the underlying soil and rocks of a particular area.” It’s possible to look at the strontium isotopes and find out if the animals ate and drank always in the same area, or if they moved around.
The reindeer have similar strontium isotope patterns, suggesting they moved from one area to another and back again while their teeth were developing. “The reindeer were probably travelling through the area during their annual migrations,” Britton says. The Neanderthal were probably aware of the reindeer migration patterns and planned their stays to make the most out of the moving herd. “This sophisticated hunting behaviour is something we see much later in the Upper Palaeolithic amongst modern human groups, and it’s really fascinating to see that Neanderthals were employing similar strategies,” concludes Britton.

A huge floating island of ice that broke off the Petermann Glacier near Greenland last August could add some excitement this summer during Newfoundland and Labrador’s tourist season.
“It’s tracking pretty close to Labrador. Our best estimate is it’s probably going to ground up there and break up,” says Charles Randell, president and chief executive officer of C-Core, a Newfoundland research and development company with ice engineering expertise.
Icebergs from the fractured ice island are expected to appear off Newfoundland’s Northern Peninsula toward the second half of July and into August. If they don’t break up or melt, they’ll make the usual trek around the province’s coastline.
That’s a bit later than the normal iceberg season, but coincides with the province’s prime tourist season, “so it should be a good year for iceberg tourism,” Randell said.
The Petermann glacier generated a lot of interest last year when it calved what started out as a 251-square-kilometre ice island. Recently, it was estimated to be smaller, at about 64 square kilometres.
Randell said icebergs are a regular occurrence, but ice islands — very large tabular icebergs like this one — are a bit of an anomaly, so C-Core’s engineers and researchers take advantage of any opportunity to learn more about them by tracking them, analyzing their melt rates and probability of breaking up.
It could just stay off Labrador and melt, Randell said, but most likely it will break up into more conventional icebergs “and give us more of the sorts of things that we’re used to seeing here.”
C-Core has been involved with tracking icebergs using satellite imagery for about 14 years. It’s a partner in an iceberg tracking website, www.icebergfinder.com, with Hospitality Newfoundland and Labrador, the provincial Department of Tourism, Culture and Recreation and the Atlantic Canada Opportunities Agency.
Most of the iceberg sightings published on the website have originated from space, using satellite data provided by the Canadian Space Agency and European Space Agency and technology to locate icebergs off the coast of Newfoundland and Labrador.

NEW YORK — Scientists have identified what may be one of the last northern refuges of Neanderthals, a spot near the Arctic Circle in Russia with artifacts dated to 31,000 to 34,000 years ago.
Stone tools and flakes found there look like the work of Neanderthals, the stocky, muscular hunters who lived in Europe and western Asia until they were replaced by modern humans, researchers reported today in the journal Science.
The site lies along the Pechora River west of the Ural Mountains, about 92 miles south of the Arctic Circle. Researchers dated it from animal bones and sand grains. Nobody has found any human bones or DNA that could provide stronger evidence that Neanderthals lived there, report the scientists, from Russia, France and Norway. The artifacts had been collected during various expeditions.
Richard Klein, a Stanford University professor of anthropology, said the artifacts do look like the work of Neanderthals, but that it’s also possible they were made by modern people instead.
Neanderthals were not previously known to be in that area, nor convincingly shown to be present anywhere at such a recent time, he said. Finding another site or human bones would help settle the question, he said.
Eric Delson, a paleoanthropologist at Lehman College of the City of New York, cited a 2006 study that suggests Neanderthals occupied a cave near the southern tip of Spain at about the same time as the new work puts them in Russia. Maybe the two locations show how Neanderthals retreated in opposite directions from the encroachment of the modern humans, he said.
NUUK, Greenland – Here, just south of the Arctic Circle, where the sea ice is vanishing like dew on a July morning, the temperature isn’t the only thing that’s heating up.
Across the region, a warming Arctic is opening up new competition for resources that until recently were out of reach, protected under a thick layer of ice. As glaciers defrost and ice floes diminish, the North is being viewed as a source of not only great wealth but also conflict, diplomats and policy experts say.
In recent months, oil companies have begun lining up for exploration rights to Baffin Bay, a hydrocarbon-rich region on Greenland’s western coast that until recently was too ice-choked for drilling. U.S. and Canadian diplomats have reopened a spat over navigation rights to a sea route through the Canadian Arctic that could cut shipping time and costs for long-haul tankers.
Even ownership of the North Pole has come into dispute, as Russia and Denmark pursue rival claims to the underlying seabed in hopes of locking up access to everything from fisheries to natural-gas deposits.
The intense rivalry over Arctic development was highlighted in diplomatic cables released recently by the anti-secrecy website WikiLeaks. Messages between U.S. diplomats revealed how northern nations, including the United States and Russia, have been maneuvering to ensure access to shipping lanes as well as undersea oil and gas deposits that are estimated to contain up to 25 percent of the world’s untapped reserves.
In the cables, U.S. officials worried that bickering over resources might even lead to an arming of the Arctic.
“While in the Arctic there is peace and stability, however, one cannot exclude that in the future there will be a redistribution of power, up to armed intervention,” a 2009 State Department cable quoted a Russian ambassador as saying.
Concern over competition in the Arctic was partly behind an extraordinary diplomatic gathering recently in Greenland’s tiny capital Nuuk. This year’s meeting of the eight-nation Arctic Council drew seven foreign ministers, including Russia’s Sergey Lavrov and Secretary of State Hillary Rodham Clinton, the highest-ranking U.S. diplomat to attend an Arctic Council session. Accompanying Clinton was a second U.S. Cabinet member, Interior Secretary Ken Salazar.
Clinton and her aides sought to call attention to climate change during the visit, highlighting new studies that show Arctic ice melting far more rapidly than scientists had believed. But Clinton also promoted a message of international cooperation in the Arctic.
“The challenges in the region are not just environmental,” Clinton said in Nuuk following talks with her Danish counterpart, Lene Espersen. “The melting of sea ice, for example, will result in more shipping, fishing and tourism, and the possibility to develop newly accessible oil and gas reserves. We seek to pursue these opportunities in a smart, sustainable way that preserves the Arctic environment and ecosystem.”
Clinton’s presence at the Nuuk meeting was intended to show U.S. support for the Arctic Council as a critical forum for cooperation and to resolve conflicts. With strong backing from the Obama administration, the council approved the first legally binding treaty in its history, a pact that sets the rules for maritime search and rescue in the region. Although modest in scope, the treaty, authored mainly by Russia and the United States, was hailed as a template for future agreements on issues ranging from oil-spill cleanup to territorial disputes.
Significantly, the eight member nations voted to establish a permanent secretariat to the council, to be located in Tronso, Norway. Clinton asserted that the region’s powers must recognize the council as the “preeminent intergovernmental body, where we can solve shared problems and pursue shared opportunities.”
“The opportunities for economic development in the Arctic must be weighed against the need to protect its environment and ecosystems. And governments will not always see eye to eye on how to achieve this balance,” Clinton said. “That’s why this council is so important.”
In the diplomatic cables obtained by WikiLeaks, there was no dispute about rapid warming under way. The predominant questions revolved around how the region’s newly accessible resources would be carved up.
