A shift in the ocean circulation has warmed the subpolar North Atlantic Ocean since 2016
Abstract The Subpolar North Atlantic is known for rapid reversals of decadal temperature trends, with ramifications encompassing the large-scale meridional overturning and gyre circulations, Arctic heat and mass balances, or extreme continental weather. Here, we combine datasets derived from sustain...
