Short summary
Using a unique annually-laminated record (varve) from the western Canadian High Arctic, we found a significant relationship between our varve record and instrumental and reconstructed Pacific Decadal Oscillations (PDOs). The negative (positive) PDO (North Pacific Index) phases increase precipitation as low sea-ice extent, warmer temperature and winds reach our region more efficiently. Our results imply that future negative PDO phases will likely impact the already rapidly warming Arctic.
