It is becoming increasingly apparent that climate change due to green house gas (GHG) emissions is accelerating, giving humanity less and less time to mitigate its ultimate effects on our global ecosystem. Interestingly, climate change was predicted (reasonably accurately) more than a century ago by Arrhenius, and then improved by Callendar in 1938 using better data, so you can’t say we weren’t warned. In this talk, I will discuss the history, the current state and future implications of anthropogenic climate change. In 2020, President Schlissel established the President’s Commission on Carbon Neutrality to develop a plan for U-M to do its part in meeting its own emission reduction strategy. I will discuss some of the important conclusions of that plan and the progress made thus far in achieving its goals. Finally, if there is time I will discuss solar technologies that can cost effectively have an enormous impact in reducing global use of fossil fuels in the near term.
