Tree rings can provide information about the climate because the width of the rings can indicate the conditions in which the tree grew. During periods of drought, trees may have narrower rings since they may have grown more slowly due to water scarcity. Conversely, during periods of ample rainfall, trees may have wider rings indicating faster growth. By analyzing the rings of trees, scientists can gain insights into past climate conditions.
