Which outcome occurs when increased thermal expansion weakens the temperature gradient along Arctic river outflow streams?

💡 Explanation

Reduced temperature gradients weaken density differences which drive thermohaline circulation intensity through convective overturning in the North Atlantic. This weakens the Atlantic Meridional Overturning Circulation. Therefore, the thermohaline circulation weakens, rather than any direct change with feedbacks or polar winds, because density gradients matter.
