Does Earth's Geomagnetic Field Strength Modulate Surface Air Temperature?: Although the evidence is strong that variability in solar activity is the primary driver of surface air temperature change, there is evidence that longer-term variations in the planet's geomagnetic field strength play a secondary role in this phenomenon.
