Because the atmosphere is so massive. Look at the surface pressure compared to Earth. Why is Mars so cold?

After all, we are talking about > 0.04% concentration -- NOT massive percentages, like Venus. The greenhouse effect on planet earth is determined primarily by WV and CO2. WV operates in the lower troposphere, CO2 above it. This can be seen quite clearly in the satellite measurements of the OLWR spectrum. > > >> >>> Why is Mars so cold? >>> > ...... and Mars ahs a very high percentage of CO2. > |
