Warming Climate Could Cause a Major Current in the Atlantic Ocean to Collapse

A new modeling study predicts that centuries of doubled atmospheric CO2 could cause the collapse of a major Atlantic current, producing dramatically different climate effects than previous models have anticipated. The analysis corrects for biases in current climate models that predict greenhouse gas forcing to drive only moderate changes to the Atlantic Meridional Overturning Circulation (AMOC), a current that carries oceanic heat northward and is a key component of climate change estimates. Existing models favor a stable AMOC, though evidence suggests that the modern AMOC is unstable and will further weaken as global warming continues. In an effort to reassess AMOC fluctuation, Wei Liu and colleagues conducted parallel experiments using two versions of the same climate model: a control run without bias correction and a bias-adjusted run, both with doubled CO2. Their adjusted model reflected a more accurate measure of AMOC stability by incorporating a different “stability indicator”; the previously-used indicator neglected the freshwater transport between the Atlantic and Arctic, the researchers say. Based on these conditions, the corrected model forecasted distinct climate changes compared to the control run – including a projected AMOC breakdown 300 years after a CO2 doubling – followed by a sweeping reduction in temperatures over the northern Atlantic, sea ice expansion in the Northern Hemisphere and a significant southward rain-belt migration over the tropical Atlantic. The results highlight the importance of identifying and reducing model biases in future climate projections.
