He found that although the amount of energy required is constant, new species form more
quickly near the equator because heat speeds up both metabolism and the rate of genetic mutations.
The Earth's magnetic field takes an average of only 7000 years to reverse its polarity, but the switch happens much more
quickly near the equator, according to the most comprehensive study yet of the last four reversals.
Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler in the
nearest deep convection source region of the South Atlantic
near Africa and the
Equator, warm over the bulk of the North Atlantic, strongly warmer where the gulf stream loses the largest portion of its heat
near 50N 25W, and strongly cooler
near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of cold water from the north whenever the Gulf Stream is running
quickly.
