Answer:

These rings can tell us how old the tree is, and what the weather was like during each year of the tree's life. ... Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area's local climate in the past

Explanation:

When scientists focus on climate from before the past 100-150 years, they use records from physical, chemical and biological materials preserved within the geologic record. Organisms (such as diatoms, forams and coral) can serve as useful climate proxies. Other proxies include ice cores, tree rings, and sediment cores.
