Arctic Currents and Climate

Warm and cool currents in the Arctic Ocean

The snow and ice that cover the Arctic reflect about 90% of the sun's energy, so the Arctic is constantly losing heat. However, the ocean currents also exchange heat; currents from the Atlantic bring warm water into the Arctic, while currents traveling southwards discharge cold water. The strong southward currents flow along the shores of northeastern North America and Asia, cooling the climate in these regions. Conversely, the North Atlantic Drift and the Japan Current warm the northwestern shores of Europe and North America, as well as the Arctic
