Description
Approximate 1000-year tree-ring chronologies for five species of high-elevation conifers at 13 sites in the Sierra Nevada and White Mountains of western North America indicated the existence of the MWP (a period with temperatures slightly higher than the long-term average) at the start of the records around AD 1000 and lasting until AD 1150.
