In 1871, some people suffered the same affliction of claiming that every month was the most extreme on record, and deluding themselves into believing that the climate is changing.
The Brisbane Courier 10 January 1871
IMAGINARY CHANGES OF CLIMATE.
We have often noticed that in the tabular statements of those compilers of weather records who write to the Times, useful and welcome as their communications are, every season is sure to be “extraordinary,” almost every month one of the driest or wettest, or windiest, coldest or hottest, ever known. Much observation, which ought to correct a tendency to exaggerate, seems in some minds to have rather a tendency to increase it.
