Carbon cycle: Fickle trends in the ocean
Nicolas Gruber1
Abstract
A model analysis of the uptake of carbon dioxide in the North Atlantic carries with it a cautionary reminder about interpreting what may be short-term trends as signals of long-term climate change.
Several observational studies have suggested that the carbon sink in the North Atlantic Ocean has decreased in recent decades, possibly reflecting the impact of long-term climate change. Writing in Global Biogeochemical Cycles, Thomas et al.1 propose that this latter interpretation needs to be viewed with great caution.

Deep convection in the subpolar North Atlantic, an important component of the global ocean circulation, has been absent in recent years. Profiling float data from the Argo programme document the return of deep mixing to the subpolar gyre in both the Labrador and Irminger seas in the winter of 2007?2008.
