School air conditioning: It’s not the heat, it’s the lack of humility

After a pleasant flirtation with early fall weather last week, Maryland is back in the sauna with temperatures in the 90-degree range and humidity levels somewhere between damp and soaking wet. One of the unfortunate side effects of this meteorological malady is early dismissal from school in those buildings lacking fully functioning air conditioning systems. Baltimore City Public Schools, long the regional leader in substandard school conditions, began that inevitable process Monday with 27 schools closing early for lack of AC or because of systems under repair.
