Abstract: The combustion of fossil fuels by human society has already driven a rise in atmospheric CO2 to levels not seen on Earth for millions of years.  Over the next few centuries, it is likely that CO2 concentrations will rise much more.  What is often overlooked is that a substantial fraction of that CO2 (i.e., 10 to 20 percent) will remain in the atmosphere for tens of thousands of years.  Much of the discussion of the impacts of climate change have neglected the impacts on these longer timescales.  I will examine some of these issues, and try to frame some of the questions one might ask about how to think about environmental change over such long timescales.


Biography: Daniel P. Schrag is the Sturgis Hooper Professor of Geology at Harvard University, Professor of Environmental Science and Engineering, and Director of the Harvard University Center for the Environment.

Schrag studies climate and climate change over the broadest range of Earth history. He is particularly interested in how information on climate change from the geologic past can lead to better understanding of anthropogenic climate change in the future. In addition to his work on geochemistry and climatology, Schrag studies energy technology and policy, including carbon capture and storage and low‐carbon synthetic fuels.

Schrag currently serves on President Obama’s Council of Advisors on Science and Technology. Among various honors, he is the recipient of the James B. Macelwane Medal from the American Geophysical Union and a MacArthur Fellowship. Schrag earned a B.S. in geology and geophysics and political science from Yale University and his Ph.D. in geology from the University of California at Berkeley. He came to Harvard in 1997 after teaching at Princeton.
