Greening in the circumpolar high-latitude may amplify warming in the growing season
We present a study that suggests greening in the circumpolar high-latitude regions amplifies surface warming in the growing season (May-September) under enhanced greenhouse conditions. The investigation used a series of climate simulations with the Community Atmospheric Model version 3-which incorpo...
