The Uncertain Principle

What makes Lofoton Island off the Norwegian coast, situated far above within the Arctic Circle, enjoy a mild climate even in the severest winter? It is set on the 68 ° latitude but records a temperature 10°C higher than any spot in Siberia at the same latitude. This is the only place in the Arctic Circle where the sea doesn’t freeze,- thanks to the Gulf Stream that washes with warm currents what would have otherwise been a bleak and dismal shore.
Researches carried out in the 50’s and 60 have helped us to understand the nature of ocean currents. There exists an oceanic deep-sea conveyor belt, which begins from this North Atlantic area. The sea being very cold its salinity is very heavy. Salt contents pour out of the frozen sea like a chimney of cold currents, which in turn is displaced by warmer Gulf streams. The cold currents begin their trek along the shores of the American continents; and are driven to the west because of horizontal westerly winds above the sea. Along the continents (at a depth of 4000 meters)these meander at 10 cm per second through ridges and valleys cutting across to the Indian Ocean and finally run into the Pacific. These currents cover a distance of some 5000kms. It would take about 2000 years to finally pour themselves into Kermadic trenches, which is some 10 kilometers deep. The same currents on the return journey are warm. How? They travel through the tropics gathering warm currents as it speeds through. These stream we know as Gulf stream as it finishes off at the Greenland.
As I said earlier one half of the loop is decidedly cold while the other is warm, which makes the hot tropics milder and brings in warmth in areas designated as winter zones.
Conclusion? If in course of history events create conditions for a nation to the status of a superpower many factors went into its rise.
I am made what I am by many factors as vast as Cosmos as itself. Nations are also held up by the same.
