内容简介
the marine ecosystem is increasingly stressed by anthropogenic changes in the earth system. models and proxy data suggest multi-centennial nutrient and biological productivity changes under sustained climate warming. we show that transient adjustments of the overturning circulation, involving interactions between the atlantic and the indo-pacific, dominates the global redistribution of nutrients on centennial timescales and contributes to a long-term decline of global biological productivity in a warming climate. similar processes may have also contributed to past climate and carbon cycle changes during the glacial period.
