Quantitative estimates are made of the effect of climate change upon dust activity during the Last Glacial Maximum (LGM), which peaked 18,000 years ago, using present-day measurements of the occurence of dust storms recalculated in the light
of information on LGM climatic change. Dust storm seasons were lengthened and dust paths were modified. Estimates based upon climate alone, without considering the increased supplies of sediment to dust source areas during the LGM, however, probably underestimate

Evolution of a dune from crescentic to parabolic form in response to short-term climatic changes: Råbjerg Mile, Skagen Odde, Denmark
Special Issue. Response of aeolian processes to global change
This study describes the geomorphological changes of the Råbjerg Mile since 1887 A.D., examines changes in characteristics of the wind and vegetation cover with time and discusses controls on dune morphodynamics and dune evolution.

A regional climate model (RCM) developed for the Hanford Site, Washington illustrates a potentially useful method for assessing eolian responses to regional climate change. The RCM is based on long-term relations between fundamental climatic

to regional and local sand transport corridors. Periods of geomorphic stability are represented by paleosols and talus accumulations. The sand ramps provide a record of the response of aeolian processes to climatic change in the Mojave Desert. Most are now
