John Parmentola - Milankovitch & The Next Ice Age

Technically, we live in an ice-age. We're in the warm, "holocene interglacial period" of the Pleistocene Ice Age that started 2.5 million years ago. How long until it changes? The government says 50,000 years. Others say we're already overdue. Dr. John Parmentola has been studying the physics of Milankovitch cycles and estimates we've got 500 years. Dr. Parmentola isn't a climate scientist, but as an MIT-trained physicist, he was intrigued by the complexity of data involved with ice-age history. He dug into Milankovitch cycles, which are a model of science developed by Serbian scientist Milutin Milankovitch which proposes that long-term variations in the Earth’s orbital cycles are responsible for ice age climate periods. What intrigued John the most were the triggers for the beginning and end of "interglacial periods" like the one we're living in right now. By interpreting solar insolation as a complex waveform, he believes he's found the trigger - and may have even found a way for mankind to control it. Dr. John Parmentola is an Adjunct Staff member at the Rand Corporation, where he works on defense, energy, science, and technology strategy and planning. His career also includes experience as a Senior Vice President at General Atomics, the Director for Research and Laboratory Management for the U.S. Army, Chief Scientist at the U.S. Department of Energy, and Chief of Advanced Systems & Operations at the Defense Threat Reduction Agency. He is an Honorary Member of the U.S. Army STs, a Fellow of the American Association for the Advancement of Science, and a recipient of the Presidential Rank Award for Meritorious Executives, U.S. Army 10 Greatest Inventions Award, the Alfred Raymond Prize, and the Sigma Xi Research Award, among many other awards and honors. Dr. Parmentola has a Ph.D. in Physics from M.I.T. and has served on the faculty of M.I.T., West Virginia University, and as a Fellow at the John F. Kennedy School of Government.
