Article Abstract
Decadal variability in the North Atlantic and its subpolar gyre (SPG) has been shown to be predictable in climate models initialized with the concurrent ocean state. Numerous impacts over ocean and land have also been identified. Here we use three versions of the Met Office Decadal Prediction System to provide a multimodel ensemble forecast of the SPG and related impacts. The recent cooling trend in the SPG is predicted to continue in the next 5 years due to a decrease in the SPG heat convergence related to a slowdown of the Atlantic Meridional Overturning Circulation. We present evidence that the ensemble forecast is able to skilfully predict these quantities over recent decades. We also investigate the ability of the forecast to predict impacts on surface temperature, pressure, precipitation, and Atlantic tropical storms and compare the forecast to recent boreal summer climate.

Some large, wide-ranging teleosts and elasmobranchs are converged to have regional endothermy, retaining metabolic heat via vascular countercurrent heat exchangers. Yet, their adaptive significance remains debated. While previous studies proposed potential benefits of elevated body temperature, enhanced controllability of body temperature enabled by heat exchangers may also be important.

Atlantification is an ongoing oceanic phenomenon characterised by the expansion of the typical Atlantic domain towards the Arctic, driving rapid oceanic and ecological changes in the European Arctic. Using reanalyses and a multi-model ensemble of unperturbed and transient preindustrial, historical and future-scenario simulations, this study shows that modern Atlantification possibly initiated in the late nineteenth century, preceded by several "Arctification" episodes in the preindustrial millennium. In the historical period, Atlantification and pan-Arctic warming superposed constructively to drive upper-ocean warming and salinification in the Barents Sea.

is a long-lived marine bivalve mollusc that inhabits the continental shelf seas of the North Atlantic Ocean at subpolar and temperate latitudes. Growth increments formed within shells can be analysed to form annually resolved and absolutely dated sclerochronologies that are considered the marine counterpart to dendrochronologies. Here, we present an updated chronology from the Fladen Ground (North Sea) that spans between CE 1410 and 2021.

UK droughts are projected to become more frequent under climate change, reinforcing the need to understand their underlying causes. Our study examines oceanic drivers of UK summer droughts and the associated teleconnection pathways. Specifically, we evaluate statistical links between standardized precipitation and streamflow indices for the UK and two North Atlantic Sea surface temperature (SST) patterns which have previously been linked to the influx of freshwater into the subpolar region.

North Atlantic Ocean circulation and temperature patterns profoundly influence global and regional climate across all timescales, from synoptic to seasonal, decadal, multidecadal and beyond. During 2023, an extreme and near-basin-scale marine heatwave developed during Northern Hemisphere summer, peaking in July. The warming spread across virtually all regions of the North Atlantic, including the subpolar ocean, where a cooling trend over the past 50-100 years has been linked to a slowdown in the meridional overturning circulation.
