Paleoclimatologists can use fossilized pollen to study the climate of the past. Once the fossil is dated they can determine what kind of plants lived at that time. From that they can start to determine the ______________ of that time period. 

• Dew Point

• Temperature 

• Barometric Pressure

• Humidity
