the northern Great Plains . A declining trend in dust emission and transport from the Sahara under RCP8.5 was detected by Evan et al. , but regional climate model experiments conducted by Ji et al.  under the same scenario indicated that overall dust loadings would increase by the end of the 21st century over West Africa. New dust sources may emerge with changing climate conditions, as Bhattachan et al.  indicate for the Kalahari Desert in southern Africa, due to vegetation loss and dune remobilisation. There is overall low confidence on future atmospheric dust loads at the global and regional scale. Models of future dust emissions are limited by the low accuracy of models of present anthropogenic dust emissions, which range from 10% to 60% of the total atmospheric dust load . A global compilation of data from sedimentary archives , remote sensing, airborne sediment sampling and meteorological station data estimated that anthropogenic dust emissions have at least doubled over the past 250 years . While future emissions of natural dust sources are projected to decrease  or remain stable , when sources of human emissions are included, projections of future atmospheric dust loads suggest that emissions may increase .
