The topic, "Northern Sea Route" has become a highly relevant point on the strategic radar screen of many business and military leaders, since global climate change now opens up a hitherto impassable sea route and positions it as a strategic alternative to the Suez route. Add to this the discovery of many easily extractable commodities and metals in the arctic area. For entrepreneurs, this setting offers new opportunities and risks; for academics, a new research context emerges. The book discusses the strategic, economic, logistic, judicial and military challenges of the future great game in the arctic sea.
