“The transition may be occurring because hotter air has more capacity to hold moisture, which in turn creates more rain, said Martin Claussen of the Max Planck Institute for Meteorology in Hamburg, Germany, who was not involved in the new study.”
Let me get this straight. The desert is already hot. But, if it gets hotter it will become greener. OK, got it.
Is this like boiling something until it freezes?

Deserts are defined by their being dry - not by being hot - there are plenty of cold deserts. If the global atmospheric temperature rises by a small amount, then the moisture carrying capacity of the air will increase by a proportionate amount. More water vapor in the air = more precipitation worldwide. And more precipitation worldwide = shrinking deserts.
