Which climatic consequence occurs when a major volcanic eruption disrupts the North Atlantic subpolar gyre?

💡 Explanation

When a volcanic eruption injects aerosols into the stratosphere, reduced solar radiation cools the North Atlantic, slowing down the subpolar gyre which drives the Atlantic Meridional Overturning Circulation (AMOC). Therefore weakened AMOC results, rather than increased cyclone frequency, enhanced carbon sequestration, or accelerated ice melt, which depend on different environmental conditions and feedback mechanisms.
