On the warming asymmetry between Europe and North America in climate change projections

North America warms more than the zonal mean, while Europe warms less than the zonal mean during the next millennia. This asymmetry can be explained by both regional and larger-scale processes. The amplification of the warming in NAM is due in winter and spring to the snow cover feedback and, in addition, to the sea ice feedback in autumn. The poleward heat transport in the Atlantic is reduced by 10%. This weakens the sst increase along European coasts in winter and therefore reduces the warming over the continent during this season
