Many decades have passed since the encouragement of the first magic numbers for climate control in museums—the 60°F, 60% relative humidity (RH) rule of Rawlins and the last three decades have seen widespread implementation of museum climate control “improvements.” An entire generation of conservators and conservation scientists have watched the accumulation (or not) of damage in collections modified (or not) by climate control. The next generation faces painful decisions about sustainability. It is time to take stock and to consider what advice to pass on. – Stefan Michalski
