The freezing point of carbon dioxide is -78.5C. The temperature at which carbon dioxide sublimates is not a fixed value. It instead is a function of the partial pressure of carbon dioxide. That value of -78.5° C is the temperature at which CO2 sublimates given a partial CO2 pressure of one atmosphere. The temperature needed to have CO2 sublimate given a ...

-98°C is as cold as it can get on Earth, in isolated places, where air and surface radiation are in equlibirum in the polar winter and no exchange happens Scambos et al 2018. Given the low atmopsheric CO2 in cold phases, extremely low precipitation rates and an isolating polar vortex around Antarctica and no isotopic signal in cores it can be doubted that ...

During an ice age little CO2 will reach the arctic,it will be absorbed by sea water in all the oceans,This will create a positive feedback,lower CO2 level in the atmosphere will make it even colder so the liquid water will absorb even more CO2. Cold water can hold large amounts of dissolved gasses,When the ice age ends large amounts of CO2 will be released ...
