Arctic sea ice is not merely a passive responder to the climate changes occurring around the world, according to new research.
Scientists at Yale University and the University of Southampton say the ongoing Arctic ice loss can play an active role in altering one of the planet’s largest water circulation systems: the Atlantic Meridional Overturning Circulation (AMOC).
AMOC has a lower limb of dense, cold water that flows south from the north Atlantic, and an upper limb of warm, salty water that flows north from the south Atlantic as part of the Gulf Stream. AMOC plays a major role in regional and global climate, affecting the Atlantic rim countries — particularly those in Europe — and far beyond. It was featured in the movie “The Day After Tomorrow.”
Here's why we must not let this happen...
