Which outcome results when the Gulf Stream weakens?

💡 Explanation

Weakening of the Gulf Stream reduces heat transport to Europe via thermohaline circulation, causing cooling, because circulation relies on density differences between warmer, saltier waters and colder, fresher waters; therefore, cooler temperatures occur, rather than increased ice, hurricane changes, or bloom enhancement.
