The thermohaline circulation of the ocean is a process that generates a giant flow pattern in which water moves around the planet. Recently, dire predictions and Hollywood movies have raised public consciousness of the impact of ocean flows on climate change. In their Perspective, Hansen et al . discuss recent observations and suggest that although the circulation may be weakening, which might lead to climate cooling in northern Europe, compensating effects make the picture richer and more… Expand

Influence of the Atlantic Subpolar Gyre on the Thermohaline Circulation
TLDR
The salinity of the Atlantic Inflow is tightly linked to the dynamics of the North Atlantic subpolar gyre circulation and its influence on the salinity are taken into account. Expand
Ocean circulation and climate at the Eemian and last glacial inception
Combining a hierarchy of climate models of varying complexity with marine proxy data, we show that the North Atlantic surface circulation played an important role for the climate of the Eemian andExpand
Response of Central European SST to atmospheric pCO2 forcing during the Oligocene – A combined proxy data and numerical climate model approach
Abstract CO 2 -induced global warming will affect seasonal to decadal temperature patterns. Expected changes will be particularly strong in extratropical regions where temperatures will increase atExpand
Interaction with the Global Climate System
The Arctic is part of the global climate system. To address the issue of climate, the fluxes of heat, salt, and fresh water must be considered. One of the most speculated reasons for rapid climateExpand
Bistability of the Atlantic subpolar gyre in a coarse‐resolution climate model
[1] High resolution models indicate that the dynamics of the Nordic Seas and the subpolar gyre is crucial for deep water formation and overturning circulation in the Atlantic. During the last decadesExpand
The Nordic Seas: An Overview
The aim of this overview paper is to provide a brief synthesis of the five review papers contained in the monograph. Prevailing south-westerly winds, oceanic flow patterns, and oceanic summer heatExpand
Global Warming: Human Intervention in World Climate
In the preceding chapter, we described climate changes that have occurred over very long geological periods. We concluded that Earth is currently in an interglacial interval within a rather longExpand
Disruption of the Atlantic Meridional Circulation during Deglacial Climates Inferred from Planktonic Foraminiferal Shell Weights
Changes in the density structure of the upper oceanic water masses are an important forcing of changes in the Atlantic Meridional Overturning Circulation (AMOC), which is believed to widely affectExpand
The Changing Climate of the Arctic
The first and strongest signs of global-scale climate change exist in the high latitudes of the planet. Evidence is now accumulating that the Arctic is warming, and responses are being observedExpand
Changes in the strength of the Nordic Seas Overflows over the past 3000 years
The Nordic Seas Overflows constitute the densest component of the deep limb of the Atlantic Meridional Overturning Circulation (AMOC). Changes in the vigour of the overflows may have had importantExpand

What Is the Thermohaline Circulation?
The term "thermohaline circulation" is widely used in the context of past and future climate change. In his Perspective, Wunsch argues that there are many different, and inconsistent, definitionsExpand
Rapid freshening of the deep North Atlantic Ocean over the past four decades
TLDR
It is shown, through the analysis of long hydrographic records, that the system of overflow and entrainment that ventilates the deep Atlantic has steadily changed over the past four decades, and this changes have already led to sustained and widespread freshening of the deep ocean. Expand
Global Climatic Impacts of a Collapse of the Atlantic Thermohaline Circulation
Part of the uncertainty in predictions by climate models results fromlimited knowledge of the stability of the thermohaline circulation ofthe ocean. Here we provide estimates of the response ofExpand
Tropical stabilization of the thermohaline circulation in a greenhouse warming simulation
Most global climate models simulate a weakening of the North Atlantic thermohaline circulation (THC) in response to enhanced greenhouse warming. Both surface warming and freshening in high latitudes,Expand
A change in the freshwater balance of the Atlantic Ocean over the past four decades
TLDR
A comparison of salinities on a long transect through the western basins of the Atlantic Ocean between the 1950s and the 1990s is presented, suggesting shifts in the oceanic distribution of fresh and saline waters are occurring worldwide in ways that suggest links to global warming and possible changes in the hydrologic cycle of the Earth.

Improved estimates of global ocean circulation, heat transport and mixing from hydrographic data
TLDR
These estimates provide a new reference state for future climate studies with rigorous estimates of the uncertainties, and resolve globally vertical mixing across surfaces of equal density. Expand
Upper layer cooling and freshening in the Norwegian Sea in relation to atmospheric forcing
Abstract Several time series in the Norwegian Sea indicate an upper layer decrease in temperature and salinity since the 1960s. Time series from Weather Station “M”, from Russian surveys in theExpand
North Atlantic–Nordic Seas exchanges
Abstract The northeastern part of the North Atlantic is unique in the sense that it is much warmer in the surface than other ocean areas at similar latitudes. The main reason for this is the largeExpand
Shifting seas in the greenhouse?
Models of the Earth's possible responses to global warming are continually being improved. The latest simulation of changes in deep flow in the Atlantic operates without several of the fudge factorsExpand
Is the Gulf Stream responsible for Europe's mild winters?
Is the transport of heat northward by the Gulf Stream and North Atlantic Drift, and its subsequent release into the midlatitude westerlies, the reason why Europe's winters are so much milder thanExpand
