Earth-Sun Distance Sharply Alters Seasons in Tropical Pacific in a 22,000-Year Cycle

Earth & Sun

New climate simulations show the annual change in the planet’s distance from the star also affects a seasonal cycle that impacts weather in North America and globally. Weather and climate modelers understand pretty well how seasonal winds and ocean currents affect El Niño patterns in the eastern equatorial Pacific Ocean, impacting weather throughout the United States and worldwide. But new computer simulations show that the effect of …
