Assuming that changes of the Earth's climate due to the effects of industrial civilization which go on before our very eyes and threaten global ecological disaster for the Earth, it is very important to understand how and why this happend on Mars. It is impossible to understand the history of the Martian climate without understanding its present state. This is accompanied by strong meridional transfers. The carbon dioxide distribution between gasous and solid states changes due to changing inclination of the equator. A Possible analogy is with changes of terrestrial glaciation and global warming.
Atmospheric aerosols have a major impact on the climate of Mars, as well as of the Earth.
On Mars, this impact is amplified as the planet passes through perihelion. Frequently, but not regularly, global dust storms, which have no to-date terrestrial analogs, are generated in this period. However, local dust storms occur on Earth in deserts. Wind transport of the dust play a major role on both planets, contributing to the growth of deserts. Such phenomena are more pronounced on Mars, and their studies may be helpful in understanding mechanisms responsible for continental environmental changes, as well as for predicting these changes.
