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.</span></p>
