An article "As Arctic Ice Vanishes, New Shipping Routes Open" on The New York Times discussed the new opportunities in shipping routes when ice continues to melt. Global warming is the key contributor of the melting ice in both North and South poles. The territory,
once melted, becomes exposed to new ways of inhabitation and channels.
At the global scale, strategic decisions for port location and use of route is essential to higher yield and to race against other nations.* Moreover, the infrastructural systems and it's respective use of specific tools were also developed to accommodate the shipping cargo industry. The largest port is the Shanghai International Port, which consists of vast ports for containers. large and dredged docks, dredged river, and tide are essential to keep the goods in the containers; as well as a location for the ship and the workers.
As the globe continues to become warmer, glacier in the Arctic became thinner over time. This will allow more ships to sail across at a shorter distance. Fountain and Patel predicted for 2030-2046, regular container ships will also be able to sail across Arctic without ice-breaking equipment in the Summer. This will greatly affect the shipping industry, especially between Asia, Europe, and North America. However, there would still be negotiation points, for insurance may be higher, and oceanic current are more unpredictable.
*During World War II, Massachusetts was a vital location for its proximity to Russia and Japan. However, this piece of information is not normally represented in maps. It was difficult to see the proximity.
