Increased winter temperatures associated with the
observed positive trend in the winter Arctic Oscillation can partially explain
trends towards earlier spring leafout in the northern hemisphere. Increased spring drawdown associated with
earlier leafout, coupled with increased winter respiration due to warmer
temperatures, indicate the trend in the winter Arctic Oscillation can help
explain observed increases in the seasonal amplitude of atmospheric CO2 concentration.
