1

How do Scientists study Earth's climates

Temperature and Rainfall (Rulers and Thermometer)

2

What are the limitations of satellite and instrumental records when studying climate

satellites and instruments have not been around forever

3

Where can scientists find clues about climate for timeframes before the 19th century

tree rings, glaciers, records

4

Why are layers, bands, and rings in natural enviromental records useful to studying climate

They tell seasons, temperatures, rainfall, and age

5

Can scientists use evidence from one form of data to determine the details of an ancient climate? Why or Why not?

No because not every place has the same climate, like not every place has trees

6

Data is an estimate

Proxy (Indirect) data

7

examples of proxy/indirect data

tree rings, ice cores, corals, lake and ocean sediments, tree pollen, or human archives

8

direct measurement example

current temperature and CO2 levels are in the atmosphere

air samples and greenhouse gases
