How scientists capture a polar bear
Each spring since 2003, Jon Aars, senior scientist at the Norwegian Polar Institute, and his team have conducted an annual polar bear monitoring program on Svalbard - collaring, capturing and taking samples from as many bears as they can across several weeks.
By studying polar bears they get a better understanding of what is happening in this part of the Arctic environment. The bears roam over large distances and, being apex predators, provide lots of information about what is happening lower in the food chain and across different Arctic species.
The Guardian accompanied Aars on an expedition to the southern end of Spitsbergen island, the largest in the Svalbard archipelago.

Greenland and Iceland saw record heat in May. What does that mean for the planet?
Human-caused climate change boosted Iceland and Greenland 's temperatures by several degrees during a record-setting May heat wave, raising concerns about the far-reaching implications melting Arctic ice has for weather around the world, scientists said in an analysis released Wednesday. The Greenland ice sheet melted many times faster than normal during the heat wave, according to the analysis by World Weather Attribution, with at least two communities seeing record temperatures for May. Parts of Iceland saw temperatures more than 10°C (18 °F) above average, and the country set a record for its warmest temperature in May when Egilsstadir Airport hit 26.6°C (79.9 F) on May 15. The findings come as global leaders put more focus on Greenland, a semi-autonomous territory of Denmark, following U.S. President Donald Trump 's comments that he would like to annex the mineral-rich island. Burning fossil fuels for electricity and transportation releases pollutants such as carbon dioxide that cause the planet to warm unnaturally fast. The Arctic is one of the fastest-warming places on Earth. Even in today's climate, the occurrence of such a strong heat wave in the region is relatively rare, with a 1% chance of occurring in a year, the analysis said. But without human-caused climate change, such an event would be 'basically impossible,' said Friederike Otto, associate professor of climate science at Imperial College London, one of the report's authors. The extreme heat was 40 times more likely compared to the pre-industrial climate. Global impacts from a melting Arctic Otto said this extreme weather event affects the world. As the Greenland ice sheet melts, it releases massive amounts of fresh water into the salty oceans. Scientists say this could slow down the Atlantic Meridional Overturning Circulation, an ocean current that circulates water from the Gulf of Mexico across the Atlantic Ocean to Europe and then the Arctic. Such a slowdown could disturb global climate and weather patterns. 'The nature of weather in the Northern Hemisphere is directly tied to what's happening in the Arctic, because that ice floor basically at the bottom of the atmosphere helps determine the weather patterns that we get,' said Waleed Abdalati, who heads an environmental sciences institute at the University of Colorado Boulder. He was not involved in the WWA analysis. The Greenland ice sheet and other ice covering the Arctic can influence where and when wind blows, how much water content the wind has and whether precipitation falls as rain or snow. Most of the melting of the Greenland ice sheet happens in June, July and August. The May heat wave means there will be a longer melting season this year. Greenland and Iceland saw record heat in May.

Skipton cellist visits Arctic to record sounds of climate change
The sound of Arctic wind howling through the strings of Sarah Smout's carbon fibre cello on the pack ice connected to the North Pole is like nothing she has heard joined a group of artists from all over the world on a trip to research and be inspired by the "breathtaking and absolutely vast" landscape of the Arctic musician and poet spent 16 days on board a specially-equipped ship in the Norwegian archipelago of Svalbard and experienced temperatures of - said she saw climate change happening before her eyes as "cracks began to form on the ice, a large shelf broke off and we were hurried back onto the boat, no longer safe on the drifting piece of ice". Smout is using music, words and sound recordings to make her debut album, which will focus on climate change in the Arctic."Music is a brilliant way to bring people together, speak to their hearts and minds and inspire them to make decisions themselves to bring about positive change," said Smout."We are witness to the climate changing all around us, but none so dramatic and fast as in the Arctic."It might be far away but what happens there affects all of us."She said visiting Svalbard had made her more driven than ever to bring the sounds she has recorded to the wider hopes listeners will connect to what is happening in that part of the world and be encouraged to protect said her current research was about water and that she and her cello, which she has named Bernard, had been on many adventurers to explore nature."I've always been fascinated by the Arctic and I think being in places and getting a sense of the place first hand sparks my own creativity," she used a hydrophone to record under water and said the sounds she had collected, such as creaking glaciers, would speak for themselves on her album.
