I am resigning as Director of the Berkeley Atmospheric Sciences Center (BASC) @BerkeleyAtmo. To reduce the odds of being mischaracterized, I want to explain my decision here. Last month, the MIT Department of Earth, Atmospheric and Planetary Sciences @eapsMIT canceled a science lecture because of the invited scientist's political views. That scientist does excellent work in areas of interest to BASC (he visited us at our invitation in 2014).
