Abstract
This paper is focused on the hypothesised connection between the main geomagnetic field and climate. Previously we have shown that on time scales from decades to centuries there is a correlation between the changes of the main geomagnetic field and climate in the Northern Hemisphere. But only correlation may not be conclusive evidence of such link, it needs an appropriate mechanism. Below we present one of the possible mechanisms - a chain of cause-and-effect relationship between cosmic rays, geomagnetic field, ozone variations and humidity at the upper troposphere / lower stratosphere (UTLS), which ultimately leads to a change in the radiation balance of the planet and, as a consequence, to long-term changes in surface air temperature.
