On September 9, 1896, The Chatham Record reported this patent:
To Cool the Atmosphere
A western inventor recently patented a scheme by which he claims he can artificially cool a whole community at little expense. At certain intervals he would erect skeleton towers-like windmill tower-each having an electric trolley wire running from bottom to top. The wire transports peculiarly made bombs to the top where they are exploded by electricity. The bombs contain liquefied carbonic acid gas, which, when liberated by the explosive, will instantly evaporate and severely chill the surrounding atmosphere.
So there you go. Problem solved.
