Abstract

Numerous studies have been published on the contribution of Earth’s magnetic field to Earth’s climate. Most of them are being focused on the upper atmosphere and the caused effects in the conductivity of the ionosphere, the transport processes of ionospheric plasma, the control of the magnetic equator and aurora zones and the correlation between the ionosphere-thermosphere system with the solar wind and magnetosphere. But what about the effects in the lower atmosphere, where there is no obvious indicator of the influence of Earth’s magnetic field, despite the existence of interesting but controversial evidence and no clear mechanism explains the relationship between magnetic field variations and climate change? The introduction of magnetic declination as a contributor to climate change is an answer for a possible mechanism. Differentiation in magnetic declination could possibly affect mid- to long-term climate. Here, we propose a mechanism based on short- and mid- to long-term variations of Earth's magnetic field in combination with space weather and how it is correlated and affects climate and weather.
