The extreme heatwave that struck Florence, with temperatures topping 35 degrees Celsius (95 degrees Fahrenheit), caused an air conditioning system breakdown in a wax anatomical room at the Natural History Museum of the University of Florence-La Specola. Extraordinary maintenance and the emergency transfer of the artifacts to refrigerated rooms have been ordered by the University, resulting in a temporary suspension of visits to the section. The museum's Waxworks Workshop has made around 1,400 wax models since 1771, making the collection one-of-a-kind in the world. The wax models, which are particularly sensitive to their surroundings, require a steady temperature of approximately 18 degrees Celsius (64 degrees Fahrenheit). At 35 degrees Celsius, they risk melting. This is the second incident in just a few weeks in the Tuscan city; at the end of June, a similar malfunction struck the Uffizi's air conditioning system. The artworks were not harmed, but the episode raises concerns about the vulnerability of cultural assets to extreme weather events. And it sounds like a warning: cultural heritage preservation is now essentially a climate adaptation issue. Emergency planning, continual microclimate monitoring, and climate-controlled reserve storage are no longer optional, but a necessity.
