Thanks to Luke for alerting us to this new research.
Following hot on the heels of recent climate revelations, such as the warming aerosols of Asian Brown Clouds, Climate Shifts, 1934 replacing 1998 as the warmest recorded year in the USA, and the new evidence for a large negative feedback due to the thinning of heat trapping clouds, Australian scientists at CSIRO have discovered a previously unrecognised deep ocean pathway linking the 3 southern hemisphere ocean basins, which is part of the global conveyer belt, or thermohaline circulation. Very important to global climate.
This is where I came in to the climate debate by initilally believing scare stories that the Gulf Stream was about to shut down and give europe a climate similar to Alaska. It turned out that the slowing down was a mis-calculation, plus ‘mean wind advection’ and the earth’s rotation are important factors in driving ocean circulations, according to Carl Wunsch.
The CSIRO news release is here:
Also on CNN who unfortunately saw fit to introduce the now customary alarmism:
“The best known of the global ocean currents is the North Atlantic loop of the Great Ocean Conveyer, which brings warm water from the Equator to waters off northern Europe, ensuring relatively mild weather there. Scientists say if the conveyor collapsed, northern Europe would be plunged into an ice age.”
Of course, this new ocean ‘supergyre’ will have to be incorporated into those diagnostic tools known as ‘climate models,’ along with the results of other recent research.
