CO2 is a gas that freezes at -109 F. So, how can a gas that freezes at such a low temperature be cooked in water ice, and ice core samples? Well, a Global Climate Climate change scientist will tell you that CO2 is soluble in water, noting that "CO2 is what gives soda its fizz – and the amount in the ice is proportional to the atmospheric level at the time the water froze. can Carbon-date it to find out the time it froze. " Alright, let's discuss this question when it comes to proving Global Warming Theory using ancient ice, shall we?
Okay so, but if the CO2 fizzes, some of the gas escapes, then the percentage of PPM would automatically be incorrect in these core ice samples. Further, CO2 is heavier than air so it will accumulate in the lower areas at the time, provided little or no wind, so the ice-core samples will be unequal, and not a good representation of a year of ice. Also, I am absolutely correct that when things heat up they will melt the previous ice, sometimes 10-years at a time, maybe a 100 years of ice core samples during a warm period, meaning we do not see those warming periods in the ice.
Remember, when you open a can of soda the CO2 escapes, fizzes to the top, not all remains soluble. I know because I have a favorite soft drink I often mix with my smoothies to add flavor. Actually, and contrary to what core ice scientists believe; no the amount in a given piece of ice would not be proportional to the atmospheric level at the time, only to that local area. I have run portable diesel equipment in sub-zero temps, you can see the CO2 fog floating around settling down, moving with the wind etc.
Ice Core samples can be valuable, but not as reliable as many would have us believe. Yes, I still believe it is wise to collect them and analyze them, but to force them to fit a climate model, or to say this warm period or that cooling period happened before or after 100s of 1000s of years ago with any certainty is suspect . We can not go back and isolate all the conditions in a lab 100s of 1000s of years ago, CO2 moves around, it takes a lot to freeze it, it melts easy, it fizzes and lets off gas, it settles due to its weight in calm conditions and will accumulate in the lowest near space, but if your core drill was 6 feet off, it was not recorded or if it was at a low spot, you got more than the average levels in your core sampling. It's not a perfect indicator, but about all we got. Think on this.
