Abstract
What is happening
• Observations of the Atlantic Meridional Overturning Circulation or
Gulf Stream System since the 1980s have shown a strengthening in
the 1990s and a weakening in the 2000s, with no clear overall trend.
• Shifts in North-east Atlantic circulation, leading to a greater
influence of warmer subtropical-origin waters which can impact
marine ecosystems and economically important fish species such as
mackerel. The changing subpolar ocean circulation is also having
impacts on the food supply for deep-sea ecosystems.
• The subpolar gyre recorded its freshest values on record in the
2010s. Ongoing freshwater build-up in the rapidly changing Arctic
Ocean may exacerbate this freshening.
What could happen
• Projections from climate models consistently project a weakening of
the Atlantic Meridional Overturning Circulation due to
anthropogenic climate change.
• Warming of Atlantic waters is expected to reduce the depth of mixed
layers and limit nutrient supply to surface layers.
