Detailed explanation-1: -Scientists can extract samples of ancient air from ICE cores. As ocean temperatures increase, the amount of carbon dioxide dissolved in ocean water has DECREASED.
Detailed explanation-2: -It was revealed that in winters during ice age The carbon dioxide level did not exceed 200 ppm whereas in summers it did not exceed 2 80 ppm. So the answer to this question is that for the past several 100 years carbon dioxide levels have never exceeded 300 PPm.
Detailed explanation-3: -Ice cores can tell us Earth’s atmospheric composition, greenhouse gases, and temperature trends from hundreds of thousands of years ago. Over the centuries, snow falling in the poles and on high mountains has been compressed into ice, trapping tiny bubbles of the ancient atmosphere.
