This is a
result of a weaker wind - driven
ocean circulation, when a large decrease in
heat transported to the deep
ocean allows the surface
ocean to warm quickly, and this in turn raises global surface temperatures.
Mauritsen said the warming of the upper
ocean and the atmosphere during the summer through reduced cooling around Europe
results in the stronger
transport of
heat into the Arctic, which is actually «pristine» in general.
Quite apart from the wider publicity given to the
heat transport problem in the Russell
ocean model (which affects all of the published GISS - E2 - R
results), and the famous rogue LU run where a negative forcing yields an overall positive net flux response (which is not rogue at all and not to be excluded according to Gavin), the WMGHG
results and particularly the relationship between Fi and ERF values now seem positively bizarre.
These processes affect the
transport of water,
heat, salinity, nutrients and carbon in the
ocean, impacting on the climate system by modifying it's ability to absorb human - emitted carbon dioxide and excess
heat resulting from increased carbon dioxide concentrations.
Sea ice is lost due to increasing
ocean heat transport into the arctic and the
resulting loss of ice causes the atmosphere to warm.
Associated with the warming, there has been an enhanced atmospheric hydrological cycle in the Southern
Ocean that results in an increase of the Antarctic sea ice for the past three decades through the reduced upward ocean heat transport and increased snow
Ocean that
results in an increase of the Antarctic sea ice for the past three decades through the reduced upward
ocean heat transport and increased snow
ocean heat transport and increased snowfall.
Perhaps the model
results do open a door for Arctic geoengineering approaches though, for instance by influencing Arctic
Ocean salinity and
heat transport or through Arctic solar radiation management.
Alternatively, it may be the
result of increased
ocean heat transports due to either an enhanced thermohaline circulation (Raymo et al., 1989; Rind and Chandler, 1991) or increased flow of surface
ocean currents due to greater wind stresses (Ravelo et al., 1997; Haywood et al., 2000), or associated with the reduced extent of land and sea ice (Jansen et al., 2000; Knies et al., 2002; Haywood et al., 2005).
The basic
results of this climate model analysis are that: (1) it is increase in atmospheric CO2 (and the other minor non-condensing greenhouse gases) that control the greenhouse warming of the climate system; (2) water vapor and clouds are feedback effects that magnify the strength of the greenhouse effect due to the non-condensing greenhouse gases by about a factor of three; (3) the large
heat capacity of the
ocean and the rate of
heat transport into the
ocean sets the time scale for the climate system to approach energy balance equilibrium.
We find that an increase in poleward
heat transport by the tropical
ocean results in a warming of the extra-tropics, relatively little change in the tropical temperatures, moistening of the subtropical dry zones, and partial but incomplete compensation of the planetary - scale energy
transport by the atmosphere.
