Ocean Currents & Climate

The Gulf Stream carries warm water to the North Atlantic Ocean, which contributes to

• a mild climate for the British Isles.

• a harsh winter in the British Isles.

• a cold-water surface current that flows to the British Isles.

• a warm-water surface current that flows along the coast of California.
