Tyndall Lectures

This annual lecture offers a historical perspective on global environmental change. The lecture is named in honor of 19th century Irish-born scientist John Tyndall FRS, whose measurements in the mid-century confirmed the significance of the greenhouse effect, which had been first hypothesized by French mathematician/physicist Joseph Fourier in 1824.

The 2015 lecture will be presented by Julie Brigham-Grette, Professor of Quaternary and Glacial Geology in the Department of Geosciences, University of Massachusetts, Amherst, on “Thin Ice — Bipolar Super Interglacials and our Possible Future”, on Tuesday, December 15, from 2:40 PM to 3:40 PM, in Moscone West 2022-2024.

The lecture will be recorded for later viewing and will also be viewable remotely in real time using the AGU Virtual Option. Further information about how to access this option will be posted here at a later date.
