As I woke up this morning, I learned that a wildfire raging in our local forest had grown to nearly 70,000 acres. A mixture of emotions subsequently flooded in, combining thoughts of concern with questions about how climate change is altering wildfire patterns. In order for scientists and land managers to better predict wildfire outbreaks and to understand the role that climate plays in their behavior, they must first examine the fire history of an area over a long period of time—longer than recorded history. Charcoal and pollen deposits in lake sediments may be able to provide answers to the mysteries of fire’s deep past. Read on to hear about this interesting approach and how one study of lake sediments mapped out 1.5 million years of fire history in China.
