Observations increasingly suggest that the ambient CGM pressure cannot exceed the limit at which cold clouds start to condense and fuel feedback that limits further condensation. Such a feedback loop tends to suspend the CGM at the threshold pressure for precipitation. The coming decade will offer many opportunities to test this principle.

Abstract
Observations increasingly suggest that the ambient CGM pressure cannot exceed the limit at which cold clouds start to condense and fuel feedback that limits further condensation. Such a feedback loop tends to suspend the CGM at the threshold pressure for precipitation. The coming decade will offer many opportunities to test this principle.
