Tropics Play More Active Role Than Was Thought In Controlling Earth's Climate

Summary:
A million years ago, global climate changes occurred due to changes in tropical circulation in the Pacific similar to those caused by "El Niño" today. Changes in atmospheric circulation triggered a large expansion of the polar ice sheets. The discovery shows that local climate changes in the tropics can create global climate changes, and emphasises the hypothesis that the tropics play a more active role than was thought in controlling the Earth's climate.
