Each day, over 10,000 times the total energy used by humanity comes down from the sun
Dr. Lawrence Krauss is an internationally-known theoretical physicist and the author of hundreds of articles and more than ten books. He received his PhD from M.I.T. in 1982 and was subsequently selected by the Harvard Society of Fellows for his exceptional scholarship. He spent nearly four decades teaching at several of the nation’s finest universities and currently serves as President of The Origins Project Foundation.
In this episode, we sit down with Lawrence to discuss his new book, “The Physics of Climate Change.” In this eye-opening conversation we discuss the carbon cycle, the history of climate science, the near-term and long-term effects of carbon emissions, potential tipping points, and the path forward.
