TL;DR: Instrumental records, proxy data and climate modelling show that multidecadal variability is a dominant feature of North Atlantic sea-surface temperature variations as discussed by the authors, and that the timing of this variability is determined mainly by external forcing, for example from volcanic eruption or solar forcing.

TL;DR: The Barents Sea is the site of coupled feedback processes that are important for creating variability in the entire Arctic air-ice-ocean system as mentioned in this paper, and it has had an important role in Northern Hemisphere climate for, at least, the last 2500 years.

TL;DR: In this paper, a multi-model analysis of Atlantic multidecadal variability is performed with the following aims: to investigate the similarities to observations; to assess the strength and relative importance of the different elements of the mechanism proposed by Delworth et al. (J Clim 6:1993-2011, 1993) (hereafter D93) among coupled general circulation models (CGCMs); and to relate model differences to mean systematic error.

TL;DR: In this article, a modulation of the Pacific Decadal Oscillation (PDO) on the summer precipitation pattern over East China during the last century is partly responsible for this characteristic precipitation pattern.

TL;DR: In this article, the authors present a holistic description of the northern maritime climate from the Last Glacial Maximum through to the projected global warming of the 21st century, including the compilation of the most complete temperature record for Norway and the Norwegian Sea to date.
