Influence of CO2 emission rates on the stability of the thermohaline circulation

Article Abstract:

It has been shown to be possible to use a basic coupled atmosphere-ocean climate model to indicate that the Atlantic thermohaline circulation depends on the rate of change of the carbon dioxide (CO2) concentration in the atmosphere. A rise in atmospheric CO2 concentration in this climate model causes temporary changes which are very similar to those in three-dimensional coupled atmosphere-ocean models. It was concluded that the atmosphere-ocean system involves critical levels of atmospheric CO2 beyond which permanent changes of the Atlantic thermohaline circulation will probably occur.

Water cycle shifts gear

Article Abstract:

The study carried out on the hydrological cycle shows that the hydrological cycle is speeding up at high northern latitudes. Details of the irreversible effects of the flow of the freshwater into the Arctic Ocean are discussed.

Models change their tune

Article Abstract:

Climate models usually tune their models to match observations. Instead of this a new approach in which the models are detuned, increases the confidence of public in projections of future warming.
