The scientific community is essentially unanimous in its conclusion that human activity, especially the burning of fossil fuels and release of other greenhouse gases, is responsible for a rapid and significant increase in the average global temperature. This warming is leading to retreating glaciers and melting polar ice sheets, phenomena that will threaten water supplies and put coastal regions at risk from rising sea levels. Other environmental changes will disrupt ecological systems and agriculture. We are already seeing more extreme storms, droughts, floods, and outbreaks of disease that only will become worse without a change in our collective behavior.
For the past six years, Dr. Bob Mitchell has been informally researching the science and politics of climate change. He has taught several short courses on the subject, including in the Pitt and CMU Osher programs, and is an active member of Citizens’ Climate Lobby. In this talk, Bob will review Earth’s remarkable climate history and provide insights into its likely future. He will then examine the human consequences of a changing climate. Finally, he will discuss technological and policy approaches that offer hope for the future, including meeting the goals of the 2015 Paris climate accords.
Dr. Mitchell has an MS in physics and a PhD in electrical engineering from CMU. His early career work on gas lasers and circuit breakers used much of the same fundamental physics that applies to climate modeling. Later he managed engineering research on automated image analysis with applications in radar, sonar, medicine, and robotics. He retired in 2014 as the industry director of the Army’s collaborative research program in robotics.
