Another paper has confirmed that the Sahel is greening. A team from South Dakota State University led by Armel Kaptué have looked again and confirmed earlier reports:
The predominance of increasing rain-use efficiency in our data supports earlier reports of a “greening” trend across the Sahel. However, there are strong regional differences in the extent and direction of change, and in the apparent role of changing woody and herbaceous components in driving those temporal trends.
That's (yet another) one in the eye for Desmog's (alleged) debunking.
