The Arctic is heating up. While China, the US and Russia rapidly boost their presence - mobilizing submarines and icebreakers - the ice at the North Pole continues to recede, creating new trade routes and golden opportunities for mining, fishing, oil and gas, but also new potential for international strife. For the first time in human history an entire ocean is opening up for new traffic. A dramatic struggle to maintain peace in the midst of a quest for power and resources is speedily unfolding - all against the most ominous backdrop of all: fast-accelerating climate change. Temperatures are rising twice as fast in the Arctic as in the rest of the world. In 2014 things took a strange turn. The Kingdom of Denmark, through its continued hold on Greenland, claimed a colossal piece of the Arctic seabed, including the North Pole, all the way to Russian waters. This followed a phenomenal stunt in which two Russian submarines planted the Russian flag at the deep bottom of the ice-covered ocean, precisely at the North Pole. In 2015, Russia formally claimed its massive piece of the seabed and the two claims now overlap extensively - and soon Canada will add its demands. As the great powers increase their Arctic military capacities, tortuous endeavours to reach a diplomatic solution to the dispute are underway. Investigative journalist Martin Breum has been on the Arctic front line for a decade, and brings this compelling story to life. He travels by ice-breaker with the researchers who try to prove ownership of the North Pole. He uncovers the stories of the 57,000 Inuit of Greenland who are fighting to mould their own place in this Arctic dynamic - between the greatest powers of the world. Thrillingly written, Cold Rush takes you straight to the modern Arctic - a region in which the future of our planet is being decided.
