Figure 19-6: Stability of
North Atlantic thermohaline circulation (THC) computed with the CLIMBER model
(Petoukhov et al., 2000). Degree of shading indicates probability of THC collapse.
Light shading denotes low probability; dark shading denotes high probability.
The higher the hydrological sensitivity (HHS = high hydrological sensitivity,
LHS = low hydrological sensitivity), the faster the rate of temperature increase,
or the greater the magnitude of temperature increase, the more likely that the
North Atlantic THC becomes unstable.
