Higher dust emissions are consistent with climate change projections indicating an expansion in the global area of drylands  and increased drought risk , but future trends in dust event frequency and intensity as a result of climate change are uncertain and will vary geographically . Combined effects of climate change and anthropogenic activities are projected to increase sand encroachment and extreme dust storms  as a result of increased aridity, accelerating soil erosion  and loss of biomass . Shifts in dust storm timings are also projected in some regions . Dustiness is projected to increase in the southern US Great Plains in the late 21st century under the RCP8.5 climate change scenario but decrease over
