The Atlantic Meridional Overturning Circulation (AMOC) is a vastly important system of water circulation. It distributes Earth’s energy and is a major controller of global climate. This energy distribution is the reason Northern Ireland has such warmer weather than Alberta, Canada, despite occupying similar latitudes.
New research is showing that Arctic sea ice (Figure 2), which has been drastically reduced by anthropogenic global warming (Stroeve et al., 2014), plays an important role in the stability of the AMOC.
