What are the effects of Atmospheric Depletion or thinning of the atmosphere on the temperatures?

Question

Mars has a super thin atmosphere and its temperature variations are over 300 degrees every day. Global Warming is a government agreed on term so as to http://www.healthcentral.com/heart-disease/news-200512-31.html downplay the real effects of atmospheric depletion and poisoning.

Answer 1

The atmosphere, or water vapor specifically on Earth, is what causes the misnamed "greenhouse effect" on the planet.  Without an atmoshpere and wind currents, the side of the planet facing the sun would be much hotter than the side facing away from the sun.  The Temperature variations noted by the Apollo astronauts on the moon were in the range of 350 degrees Celcius.

If the planet Earth were to loose part of the Atmosphere, or as in the case of an ice age, were to loose atmospheric humidity and night time cloud cover, The planet would be cold enough at night that the heat of the day would not be able to melt all the resultant ice.

I am not sure what coorelation you are trying to make between atmospheric depletion and ultrafine soot particles in the air, but any depletion in our atmoshphere would result in more heat being radiated out into space at night than the planet could absorb during the day for quite some time.
