October 8, 2018: Professor Richard Lindzen said the UN IPCC report released this week had reduced the alleged tipping point from 2C to 1.5C because there had been no significant warming for 20 years. “Warming of any significance ceased about 20 years ago, and 2C warming was looking increasingly unlikely.” Professor Lindzen provided a lecture for the Global Warming Policy Foundation in London, England at the Institution of Mechanical Engineers. Lindzen is an “American atmospheric physicist known for his work in the dynamics of the middle atmosphere, atmospheric tides, and ozone photochemistry. He has published more than 200 scientific papers and books. From 1983 until his retirement in 2013, he was Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology. He was a lead author of Chapter 7, “Physical Climate Processes and Feedbacks,” of the Intergovernmental Panel on Climate Change’s Third Assessment Report on climate change.

Professor Lindzen is speaking to a non-technical audience and explains his terms well.
