To determine air temperature at the time it was formed, scientists commonly study:
1. **Ice cores**: These contain layers of ice that trap air bubbles, providing records of past temperatures and atmospheric composition over thousands of years.
2. **Tree rings**: The width and density of tree rings can indicate the climatic conditions during the years of the tree's growth, including temperature.
While fossilized pollen and certain chemical isotopes can provide clues about past climates, they are not as direct indicators of temperature as ice cores and tree rings. Fermentation shells are not typically used for this purpose.
