Abstract:
Climate change can lead to a substantial reduction of the strength of the
thermohaline circulation in the world oceans. This is often thought to have severe
consequences particularly on the North Atlantic region and Northern andWestern
Europe. The integrated assessment model FUND is used to estimate the extent of
these impacts. The results indicate that, owing to a slower warming (rather than
cooling) of the regions most affected by a thermohaline circulation collapse, climate
change induced damages in these regions would be smaller in case of a shutdown
of the thermohaline circulation. However, even with a thermohaline circulation
collapse, the total and marginal impacts of climate change are negative.
