Abstract
Some of the possible mechanisms for changes in the earth's surface temperature due to a depression of the geomagnetic field are described and commented upon. For example, as a result of the field depression, charged particles, such as galactic and solar cosmic rays, are expected to impinge upon air molecules in the stratosphere, even at lower latitudes. This may lead to an increase in NO concentration, and a subsequent decrease in ozone content in the atmosphere. Depletion of ozone would cause climatic changes to some extent and/or some biological effects.
A brief discussion is also given of some effects of magnetospheric deformation.
