We will have a full slate of three talks. Join us to learn about climate change & air pollution, solar geoengineering, and the role of the US Geological Survey from its new director. Abstracts for the talks are here. Non members are always welcome, and there is no formal dress code for the audience. Details of the talk, including the Zoom link, will be sent to members shortly. Contact Michael Ackerson (ackersonm[at]si.edu) for the Zoom link if you do not have it.
