What a naive statement. Water ice can cool things, water steam can heat them. You are confusing the conditions with the substance. Dry ice is manufactured by removing energy until the gas changes phase and becomes a solid. That solid CO2 can then absorb energy from the environment to return to a gaseous state.
You are disagreeing with something I did not say, your comprehension suffers a bit.
CO2 is used to keep stuff cold, it does a better job at that then ICE.
Dry ice is made by removing energy? You have zero understanding of CO2 and how it is turned into dry ice yet you claim to understand CO2 in the atmosphere?
Dry ice is made by freezing and pressurizing CO2 in its gaseous form, it then becomes a liquid, which is further pressurized, causing some of the CO2 to escape, which results in an extreme drop of temperature which freezes the liquid into a block.
If you are so naive to make a statement that is not close to being accurate about a simple process concerning CO2, you have zero understanding of CO2 in the atmosphere.
