The Sun. It inspires songs, warms us, and grows our food. Life on land and in the oceans, the daily weather, and long-term climate patterns happen primarily because of energy we receive from our closest star. Even tiny variations in that energy can affect the workings of our planet’s atmosphere.... Read More
