There's a theory that the Sahara alternates between desert and green every X thousand years, dramatically altering the Mediterranean, European, and African climates.
And BTW our species is conducting its largest peaceful "mobilization" ever to deal with this virus; it's actually quite inspiring.

This is a funny way to phrase the causation. The state of the Sahara is surely not exogenous -- the transition must be caused by the climate. (It can then contribute further, but why attribute the changes to an intermediary effect?)
