Short summary
It is often claimed that a relationship between atmospheric temperature and geomagnetic activity exists. The aim of this paper is to highlight how the use of statistical tests, used to establish such a relationship, can be prone to misinterpretation when temporal and spatial autocorrelations are not taken into account. When these autocorrelations are considered, the relationship between temperature and geomagnetic activity no longer exists.
