Abstract
The present authors propose in this paper that a connection exists between the variations of the Earth’s magnetic field during polarity reversal and climate change. The mechanism by which the variations of the internal magnetic field could trigger climate changes would be produced by the influence of the internal magnetic field on Galactic Cosmic Rays (GCR), since the geomagnetic field (GF) provides shielding to such radiation.
