How does the Gulf Stream affect climate?

• A. It cools Europe
• B. It carries warm water from the tropics toward Europe, making climate milder than expected
• C. It causes droughts in Europe
• D. It stops hurricanes from forming in the Atlantic

Answer: (B)

Heat transport by ocean currents affects climate. The Gulf Stream moves warm water from the tropics northward toward Europe, which releases heat into the surrounding air and helps keep Western Europe’s winters milder than its latitude would suggest. That warmth is the reason the climate there is more temperate than one might expect.

So the best description is that it carries warm water toward Europe, making the climate milder than expected. The other statements don’t fit because this current is a warm one and tends to warm, not cool, the nearby regions; it’s not the primary cause of droughts in Europe, which are driven by broader atmospheric and seasonal patterns; and it does not stop hurricanes from forming—hurricanes require warm surface waters to form, and the Gulf Stream can influence their paths and intensity but does not prevent their development.
