Climate change: Unstable Atlantic deep ocean circulation may hasten 'tipping point'

A new study looking at past climate change asks if these changes in the future will be spasmodic and abrupt rather than a more gradual increase in the temperature. Today, deep waters formed in the northern North Atlantic fill approximately half of the deep ocean globally. In the process, this helps moderate the effects of global warming. Changes in this circulation mode are considered a potential tipping point in future climate change that could have widespread and long-lasting impacts. Until no...
