Here is a thread on the AMOC (Atlantic Meridional Overturning Circulation):
Climate change might not slow ocean circulation as much as thought
Wen et al. had a paper out earlier this year that modeled the effect of the warming of the Tibetan Plateau in central Asia on North Atlantic circulation. The teleconnections resulted in less precipitation over the Atlantic and thus higher salinity. This enhances the deep-water formation in the subpolar North Atlantic and thus strengthens the AMOC.
