Ancient Plankton will Help Scientists Predict Climate
Experts recorded the highest level of CO 2. This was previously observed during the geological era. About 20 years ago, experts learned that they could establish past temperature indicators by conducting a chemical analysis of a particular type of petrified plankton shell, which was called foraminifera. It turned out that the size of the unicellular shell organisms may be incorrect due to the chemistry of the ocean, in connection with which the researchers used the fat created by coccolithophores.
In the Pacific Ocean, the temperature difference between the eastern and western sides decreased, but it was weakly manifested. These data from the Pliocene are combined with the information that was predicted by future climate models with a high concentration of carbon dioxide.
