    Predicting Future Climate Change and its Impacts

    Dr. David Chipping

    Dr. David Chipping is Emeritus Professor of Geology from Cal Poly. He received a BS in geology from the Cambridge University, and an MS and PhD in geohydrology and geology from Stanford University. He joined the faculty at Cal Poly in 1971. While spending much of his life kicking plants out of the way to see the rocks, his wife, Linda, got him to kick the rocks to see the plants. In the late 1980s he started doing conservation work with the chapter and continues to this day. He has been state CNPS Conservation Director, has served on the CNPS Board of Directors, has served as chapter
    president, and is a Fellow of the Society. He is heading up a breakout session on Climate Change at the CNPS Conservation Conference the week before our meeting and will also report on how that came out.

    Chapter meetings are generally held the first Thursday of the month at the San Luis Obispo Vets Hall on Grande Ave near the corner of Monterey Street.

    Our meetings kick off with a social time that begins at 7:00 p.m.  This  is a time to sample the treats that members have brought along to share,  and browse the book table. The meeting starts at 7:30 p.m. with some  brief announcements before the program begins.

    Speakers and notes from Chapter Meetings are documented in each  Obispoensis newsletter. Please see the Obispoensis archive for PDF file  of each newsletter.
