Science Daily, Stuff, Eurasia Review, The Earth Institute, Phys.org and Futura reported that a study led by George Denton, Libra Professor in the University of Maine School of Earth and Climate Sciences, and Aaron Putnam, assistant professor, suggests that ice age climate change may be driven by the westerly winds of the Southern Hemisphere which facilitate the release of energy from tropical ocean waters.

The mechanism, dubbed the Zealandia Switch, relates to the general position of the Southern Hemisphere westerly wind belt the strongest wind system on Earth and the continental platforms of the southwest Pacific Ocean, and their control on ocean currents. Shifts in the latitude of the westerly winds affects the strength of the subtropical oceanic gyres and, in turn, influences the ....
