New CO2 Reservoir Discovered on Mars

If you’ve followed Mars science for long, you know that the question of where the atmosphere went is a major one. Evidence points to liquid water on the surface of Mars, and that’s only possible if the atmospheric pressure is high enough and the surface temperature is warm enough. Adding CO2 to the atmosphere would increase both temperature and pressure, so a lot of scientists have been looking for carbonate rocks that might be trapping the CO2 that used to be in the atmosphere.

Well, this week a new article in Science reveals that there is a huge amount of CO2 trapped as dry ice near the South Pole!
