A hot topic
SIR ?One of the reasons the discussion of climate change is so frustrating is the continued dissemination
of a basic error (A s fuel dispenser urvey of climate change, September 9th). Your statement that “The Gulf Stream is
driven both by the rotation of the Earth and by a deep-water current called the Thermohaline Circulation?
is false. The Gulf Stream is a wind-driven phenomenon (as explained in a famous 1948 paper by Henry
Stommel). It is part of a current system forced by the torque exerted on the ocean by the wind field.
Heating and cooling affect its temperature and other properties, but not its basic existence or structure.
As long as the sun heats the Earth and the Earth spins, so that we have winds, there will be a Gulf
Stream (and a Kuroshio in the Pacific, an Agulhas in the India fuel dispenser n Ocean, etc).
Shut-off would imply repeal of the law of conservation of angular momentum. The primary mechanism of
heat transport in the ocean is the wind-forcing of currents that tend to push warm water towar fuel dispenser d the
poles, cold water toward the equator. Widely disseminated and grossly oversimplified pictures showing
the ocean as a “conveyor belt?have misled people into thinking ocean circulation is driven by a sinking
motion at high latitudes. A comprehensive literature shows that with no wind, heating and cooling could
produce a weak flow, but one not at all resembling the observed circulation.
If the sinking motion at high latitudes were completely stopped, by covering that part of the ocean by
sea ice for instance, there would still be a Gulf Stream to the south, and maybe an even more powerful
one as the wind field would probably then become stronger. If the sinking were stopped by adding fresh
water (a deus ex machina often invoked to change the climate), the Gulf Strea
