The calculations can not «exclude the possibility of dust emission bright enough to explain the entire excess signal,» the team writes. (sciencenews.org)
The 90 % confidence level is estimated to be ± 0.2 W m — 2, reflecting the uncertainty in total dust emissions and burdens and the range of possible anthropogenic dust fractions. (ipcc.ch)
From this perspective, the model projections suggest that rainfall increases would not be sufficient to support sufficient vegetation to stop dust emission. (pnas.org)
