Simulation of abrupt climate change induced by freshwater input to the North Atlantic Ocean
Article Abstract:
The thermohaline circulation (THC) in the North Atlantic Ocean varies with the differences in the freshwater input. A combined ocean-atmosphere model explains the decline of the THC as due to the massive movement of the freshwater into the northern North Atlantic Ocean. Following the initial decline, the THC rises by an increase in the sea-surface temperature and the sea-surface salinity. Such North Atlantic climate changes probably took place in the Younger Dryas Ocean during the glacial and postglacial periods.

Simulated response of the ocean carbon cycle to anthropogenic climate warming
Article Abstract:
The Intergovernmental Panel on Climate Change's 1995 report includes several CO2 emission models that would allow stabilization of atmospheric CO2 at levels between 350-1,000 ppm. However, the illustrations do not take into account the changing ability over time of the land and ocean to act as a sink for anthropogenic CO2. A new simulation of global warming focuses on the ocean carbon sink covering the period from 1765-2065. Details of the study are presented.

Century-scale effects of increased atmospheric CO2 on the ocean-atmosphere system
Article Abstract:
An integrated climatic model looking at the long-term effects of doubling and quadrupling atmospheric carbon dioxide levels show that, at four times current levels, thermohaline circulation ceases. Doubled levels lead to worldwide temperature increases of 3.5 degrees C and sea levels 1 meter higher; quadrupling it about doubles these effects. The latter also deepens the ocean thermocline and prevents ventilation of the deep ocean.
