Richard Lindzen is an atmospheric physicist and retired Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology. He earned an A.B. in physics, and an S.M. and Ph.D. in applied mathematics from Harvard University.
Lindzen has made substantial contributions to the field, with papers published on topics such as hydrodynamic instability, planetary atmosphere, atmospheric effects, Hadley circulation, heat transport and climate change. He holds a skeptical view of climate change and has questioned the validity of the computer models used to forecast climate.
His most recent work has explored the idea of Earth acting like an infrared iris, called the iris hypothesis. In this theory, he studies the feedback loop between CO2 levels, atmospheric conditions and planetary warming. While strenuously rejected by many other scientists, Lindzen has openly questioned the validity of current climate models due to their handling of water vapor and surface temperature.
Lindzen has been an antagonist in the climate change fight, providing just enough contrary arguments to diminish and disrupt progress being made. He has also challenged the notion that cigarette smoking contributes to lung cancer and the dangers of second-hand smoke. These arguments offer no real value and appear to be representative of his reputation as a contrarian.

Richard Siegmund 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. He has criticized the scientific consensus about climate change and what he has called "climate alarmism."Source: Wikipedia
