Cohen en nog andere zeggen dat een warme Noordpool leidt tot koudere continent (in de winter). Ander onderzoek bevestigt dat niet.
Abstract
The emergence of rapid Arctic warming in recent decades has coincided with unusually
cold winters over Northern Hemisphere continents. It has been speculated that this “Warm Arctic, Cold
Continents” trend pattern is due to sea ice loss. Here we use multiple models to examine whether such a
pattern is indeed forced by sea ice loss specifically and by anthropogenic forcing in general. While we
show much of Arctic amplification in surface warming to result from sea ice loss, we find that neither sea ice loss nor anthropogenic forcing overall yield trends toward colder continental temperatures. An alternate explanation of the cooling is that it represents a strong articulation of internal atmospheric variability, evidence for which is derived from model data, and physical considerations. Sea ice loss impact on weather variability over the high-latitude continents is found, however, to be characterized by reduced daily temperature variability and fewer cold extremes.
