1). How might the Arctic Ocean affect the region's (Russia and the Republics) climate?

A: This ocean might affect the region's climate as its wind currents contribute to this region's climate?

That's part of it. What else?

A: This ocean might affect the region's climate as its wind currents contribute to this region's climate, as well as by its own location as it is near the North Pole?

Tell me about the Arctic Ocean's temperatures.

You can read about the Arctic Ocean's climate in this article.

Some of the lowest recorded temperatures in the Arctic Ocean were recorded in Siberia around -58°F (-50°C). The average Arctic Ocean's temperature in the summer is 50°F (10°C) although in some places, temperatures can reach 86°F (30°C) for short periods.

Large bodies of water greatly influence temperatures of land that's close to them. The Arctic Ocean is very cold and has glaciers and ice bergs in it.

A: This ocean might affect the region's climate as its wind currents and temperature contribute to this region's severely cold climate?

Right.
