Perched on a cliff above Greenland's Helheim glacier, I tried calling my wife in New York on a satellite phone. Before I could leave a message, an explosion broke the arctic silence. More explosions followed. I ran across a muddy tundra to a video camera on a tripod overlooking the glacier and ripped off the trash bag I had used to protect it. I hit record as fast as I could focus. The popping sounds morphed into a low rumble. Over the next half hour, the ice broke apart and a four-mile wide chunk tumbled into the sea in a process called calving - one rarely witnessed on this scale.

When he's not out on the Arctic tundra with his 2,000 reindeer, his dog and Whitney Houston blasting through his headphones, Nils Mathis Sara is often busy explaining to people how a planned copper mine threatens his livelihood. Along with other Sami herders and fishermen, the 60-year-old is in a standoff with the mine owners, Norwegian officials and many townspeople that is, after six years, coming to a head. It is a litmus test for the Arctic, where climate change and technology are enabling mineral and energy extraction, shipping and tourism while threatening traditional ways of life and creating tensions among its four million inhabitants.

In Russia's remote Arctic regions reindeer herding has been a way of life for centuries. Each winter herders in Russia's sparsely populated Nenets Autonomous District corral their reindeers into open-air pens before selecting weak animals to be culled. The cull helps to preserve the region's fragile tundra by keeping herd sizes down, and local people sell reindeer meat, hide and antlers to make a living. Krasnoye is the only settlement in the Nenets region connected by road to the regional capital, Naryan-Mar, which is over 2,000 kilometres north of Moscow. Temperatures can sink below minus 40 degrees Celsius in winter. REUTERS/Sergei Karpukhin TPX IMAGES OF THE DAY. SEARCH "REINDEER ARCTIC" FOR THIS STORY. SEARCH "THE WIDER IMAGE" FOR ALL STORIES.
