How Ice Ages Happen: The Milankovitch Cycles
I made two follow up videos explaining where we are in the cycle (https://www.youtube.com/watch?v=eB3DJtQZVsw) and answering frequently asked questions (https://www.youtube.com/watch?v=49Wk1g_XBs8) This video explains how the climate changes naturally over hundreds of thousands of years and is unrelated to any changes over the past century. Please see my follow up video. The Milankovitch Cycles are changes in the Earth's orbit and rotation that cause the Earth's climate to change over hundreds of thousands of years. For more information, I recommend Dan Britt's lecture on the history of climate: https://www.youtube.com/watch?v=Yze1YAz_LYM
