The Franco-Croatian symposium on climate change has been a huge bore today. All speakers showed slides with loads of data that nobody could follow. The only interesting slide I saw was that of the average annual temperature on the planet between the late Nineteenth Century and the early Twenty-First Century, when the measurements could be trusted. In spite of all the jigs and jags, the temperature steadily increased. The only two periods when the global temperature was not rising were those of World War I and II. A simpler demonstration of the connection between the number of people on the planet and its temperature could not be found, but the speaker skipped the obvious point. I immediately thought of a comment about the possible benefits of World War III, but I kept my mouth shut in the end. The symposium was crowded, but I wondered about the participants’ wherewithal.
