The Nenets people of Russia, who herd reindeer high in the northern Arctic, are suffering the effects of climate change. Their homeland is changing, as the permafrost continues to melt - and that means that herders are often cut off from medical care for longer periods during the summer. <br />The indigenous nomads of the Archangel Oblast are forced to herd their reindeer onto summer pastures earlier - and to keep them there longer. That means they spend more time away from regular medical care and they face growing difficulties finding food. Leonid Subov, a doctor and researcher at the Institute of Polar Medicine in Archangel, goes north to check up on the Nenets people.
