This project aims to place 20th century climatic change into a longer-term context of inter-decadal climatic variability spanning the last 2000 years. We will:
1) Essentially triple the number of available proxy Arctic climate records that extend beyond the Little Ice Age to previous warm intervals to capture centennial-period modes of climatic variability.
2) Explore the role of volcanism, solar irradiance, and inherent modes of climate variability to explain observed patterns in the proxy data using climate modeling experiments.
