Short summary

During the last ice age, Northern Hemisphere ice sheets reshaped global climate. They shifted North Atlantic winds southward, increasing summer rainfall across Eurasia. They also altered tropical and Southern Hemisphere weather patterns, affecting rainfall far beyond the ice-covered regions. Our results show that the height and shape of the ice sheets had a much greater influence on global wind and rainfall patterns than changes in Earth’s orbit, greenhouse gases, or surface reflectivity.
