This data visualization showing ocean currents around the world uses data from NASA’s ECCO (Estimating the Circulation and Climate of the Ocean) model. The model pulls data from spacecraft, buoys, and other measurements.

Is the Atlantic Overturning Circulation Approaching a Tipping Point?

The Atlantic Meridional Overturning Circulation (AMOC) has been unstable in the past. These instabilities are due to two different types of tipping points, one linked to amplifying feedbacks in the large-scale salt transport and the other in the convective mixing that drives the flow. These tipping points present a major risk of abrupt ocean circulation and climate shifts.
