The research team spent years analyzing the core sample drawn from Kirman Lake in the Central Sierra, which revealed California’s climate history layer by layer for 10,000 years.
- Charcoal deposits indicate when wildfires were more prevalent.
- Layers of fossilized pollen shows eras of more pine trees or drier sagebrush.
- Shells from mollusks indicate times of deeper water.
- Single-celled algae and molecules of carbon and nitrogen give clues to the lake’s depth and salinity, and the abundance or waning of plant and animal life.
From 6,000 to 1,000 B.C., during a time geologists refer to as the mid-Holocene…
