Fickle Trends In The Ocean

摘要

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. propose that this latter interpretation needs to be viewed with great caution. From their modelling work, they argue that the observed trends instead reflect fluctuations on a decadal timescale that are a response to climate variability in the North Atlantic region.
