Arctic and North Atlantic Oscillation phase changes are recorded in the isotopes (δ 18 O and δ 13 C) of Cassiope tetragona plants
Abstract The Arctic and North Atlantic Oscillations (AO/NAO) are large‐scale annual modes of atmospheric circulation that have shifted in the last 30 years. Recent changes in arctic climate, including increasing surface air temperature, declining sea ice extent, and shifts in the amounts seasonality...
