Interpretation of Pleistocene Climate 



I believe these basins afford a feasible approach to the problem of past 

 climate that has not been exploited. I hope that with further work it

will be possible to make a quantitative estimate of Pleistocene climate by 

 comparing the Pleistocene and present hydrology of the basins. The 

 problem is, indeed, rendered complex by the variables that are involved
