The economic impact of a shutdown of the Thermohaline Circulation: an application of FUND
AbstractThe integrated assessment model FUND 2.8n is applied in an analysis of the overall economic consequences in a scenario of a shutdown of the thermohaline circulation (THC). Monetized market and non-market impacts of changes in environmental conditions following a THC collapse are determined for 207 individual countries. Eight different response patterns can be identified. The dominant pattern is that a THC shutdown has an offsetting effect on the underlying warming trend. Depending on whether the impacts of warming are initially beneficial or detrimental, the economic effects of a THC collapse show distinct regional variability. Key economic sectors affected in a THC shutdown scenario are water resources and energy consumption, as well as cardiovascular and respiratory diseases among health impacts. The maximum, national impact of a collapse of the THC turns out to be of the magnitude of a few per cent of GDP, but the global impact is much smaller. Considering the low probability of occurrence, a THC shutdown does not call for drastic action at present.
