Is the Sahara Desert Getting Browner and Drier?

The planet is not getting browner and drier, which was the apocalyptic vision. Many of the areas that were really brown and dry are actually seeing vegetation ingress in a manner unprecedented even up to 15 years ago. I mean, 15% increase in greening is just, it's almost beyond comprehension. The benefits weren't even acknowledged until maybe the fifth assessment report in the IPCC.
