Ice to see you!

Erich Fisher Episode 9

Why does Earth experience ice ages? In this episode, Mikey, Colton, and Dr. Erich explore what causes seasons, how the changes in seasons are related to the way earth is hurtling through space around the sun, and how all of this influences paleoclimates, like the shifts between glacial and interglacial periods, and even human evolution. Phew!
