  3. Studies link AMOC variability to abrupt climate change • Anthropogenic forcing could cause the AMOC to shut down, causing global cooling. • We don't know much about AMOC • What's its current state? • On what time scales does the AMOC vary? • What causes these variations? • What impacts can we expect from AMOC variability? • Can we predict them? • Solution: design & install a monitoring system Why do we study the North Atlantic Meridional Overturning Circulation?
