Global torms on mars common

[Yazeran]

Actually dust storms that cover the intire planet of Mars is not uncommon, as the first american probe orbited mars, they at first couldn't get any images of the surface, as a large storm covered the surface. Only the volcanic peaks (olympos mons and the three other volcanoes on the 'Tharis ridge' vas visible due to their huge height. That storm lasted several months if i recall correctly.

This storm is just a large one. It'll most likely be over in 2 months anyway.

As to the melting point of CO2, one has to remeember that CO2 doesent melt, it sublimates, as the pressure on mars (and earth) is lower than the critical pressure for liquid CO2. Heating the mars atmosphrere do vaporise more CO2, but it is doubtfull if much more than usual during the southern summer is vaporized.
atmospheric pressure on mars rises during the summer on the southern hemisphere, as most of the CO2 is bound here and sublimation of CO2 increases the pressure. Similarly in southeren winter, the CO2 precipitates out.
