With the melting ice in the Arctic Ocean because of the Climate Change, the Northern Sea Route, connecting Europe with East Asia, along the coast of Siberia, becomes economically accessable.
Some maps to show that in the light of future geopolitical effects.
Hereby three maps, centered near or at the North Pole, not distorting distances by the usual Mercator projection, that show how short distances become along the Arctic Sea Route, or Polar Silk Route as the Chinese call it, and the territorial claims.
Ships with Russian LNG from the Yamal Peninsula near Murmansk, need only two weeks to travel to India instead of four weeks through the Suez canal, halving the operational cost and investment for the transport, easily offsetting the nuclear icebreaker cost, because they are hardly needed.
For Putin important enough to visit the LNG port this year. For Xi-Jinping important enough to build up good ties with Norway, Denmark etc.
Also because of mineral resources in the Arctic, including gas, and the military strategic position, the Arctic is transforming from a barren, submarine only ice field, to a competed geopolitical area.
The Northern Sea Route will no doubt strtenghten the Russian position, and good ties between Russia and China. Technically from international law Denmark has a gigantic share of the Northpole area because the Danish Greenland continental shelf extends to the North Pole.
