The fate of sea ice in the Arctic Ocean in the coming years and decades is dependent upon our understanding of the complex ocean–ice–air interactions and feedbacks to the system. A new paper by Carmack et al. identifies the critical processes, key questions, and required elements for a research agenda to study this new Arctic environment.
The Atlantic Meridional Overturning Circulation (AMOC), a large-scale circulation pattern in the Atlantic, plays a central role in climate through its heat and freshwater transports. New research proposes monitoring a specific region that may enable scientists to better predict AMOC variability and future climate.
In the Northwest Atlantic, the ensemble of global climate models has a warm bias in sea surface temperature due to a misrepresentation of the Gulf Stream position; thus, existing climate change projections could be underestimating the warming rate in the upper ocean by two to three times, according to new research by Saba et al.
Climate model projections provide a compelling reason to believe that anthropogenic warming will lead to a pronounced reduction in Arctic sea ice extent over the course of this century and beyond, but there is no reason to expect this long-term sea ice retreat to occur steadily through time.
The underlying physical driver for the decadal variability in the Gulf Stream path and the regional biogeochemical cycling is linked to the low-frequency variability of the large-scale ocean circulation in the Atlantic, also known as Atlantic meridional overturning circulation (AMOC).
