In recent years, two alarming trends in North Atlantic climate have been noted: an increase in the intensity and frequency of Atlantic hurricanes and a rapid decrease in Greenland ice sheet volume. Both of these phenomena occurred while a significant warming took place in North Atlantic sea surface temperatures (SSTs), thus sparking a debate on whether the warming is a consequence of natural climate variations, anthropogenic forcing, or both; and if both, what their relative roles are.

Evidence for multiple drivers of North Atlantic multi-decadal climate variability
[1] Observed North Atlantic Ocean surface temperatures have changed in a non-monotonic and non-uniform fashion over the last century. Here we assess the relative roles of greenhouses gases,
North Atlantic Multidecadal SST Oscillation: External forcing versus internal variability
Abstract The Atlantic Multi-decadal Oscillation (AMO) depicts the swings of North Atlantic basin-wide sea surface temperature (SST) between warm and cold phases on a multi-decadal time scale. The
Aerosols implicated as a prime driver of twentieth-century North Atlantic climate variability
Systematic climate shifts have been linked to multidecadal variability in observed sea surface temperatures in the North Atlantic Ocean. These links are extensive, influencing a range of climate
The Role of Forcings in the Twentieth-Century North Atlantic Multidecadal Variability: The 1940–75 North Atlantic Cooling Case Study
AbstractResults from a study inspecting the origins of multidecadal variability in the North Atlantic sea surface temperature (NASST) are presented. The authors target in particular the 1940–75
North Atlantic 20th century multidecadal variability in coupled climate models: sea surface temperature and ocean overturning circulation
Abstract. Output from a total of 24 state-of-the-art Atmosphere-Ocean General Circulation Models is analyzed. The models were integrated with observed forcing for the period 1850–2000 as part of the
Reconciling roles of sulphate aerosol forcing and internal variability in Atlantic multidecadal climate changes
The interdecadal basin-wide warming and cooling cycle of the North Atlantic Ocean, known as the Atlantic multidecadal variability (AMV), influences not only the Euro-Atlantic climatic conditions, but
Robust features of Atlantic multi-decadal variability and its climate impacts
[1] Atlantic Multi-decadal Variability (AMV), also known as the Atlantic Multi-decadal Oscillation (AMO), is characterized by a sharp rise and fall of the North Atlantic basin-wide sea surface
Influence of the North Atlantic SST Variability on the Atmospheric Circulation during the Twentieth Century
The ocean–atmosphere coupling in the North Atlantic is investigated during the twentieth century using maximum covariance analysis of sea surface temperature (SST) and 500-hPa geopotential height
Climate Changes of Atlantic Tropical Cyclone Formation Derived from Twentieth-Century Reanalysis
AbstractWhereas some studies linked the enhanced tropical cyclone (TC) formation in the North Atlantic basin to the ongoing global warming, other studies attributed it to the warm phase of the

Twentieth century north atlantic climate change. Part I: assessing determinism
Abstract Boreal winter North Atlantic climate change since 1950 is well described by a trend in the leading spatial structure of variability, known as the North Atlantic Oscillation (NAO). Through
Twentieth century North Atlantic climate change. Part II: Understanding the effect of Indian Ocean warming
Abstract Ensembles of atmospheric general circulation model (AGCM) experiments are used in an effort to understand the boreal winter Northern Hemisphere (NH) extratropical climate response to the
Forced and unforced ocean temperature changes in Atlantic and Pacific tropical cyclogenesis regions
In experiments in which forcing factors are varied individually rather than jointly, human-caused changes in greenhouse gases are the main driver of the 20th-century SST increases in both tropical cyclogenesis regions.
Atlantic hurricane trends linked to climate change
Increases in key measures of Atlantic hurricane activity over recent decades are believed to reflect, in large part, contemporaneous increases in tropical Atlantic warmth [e.g., Emanuel, 2005]. Some

Abstract This study identifies interdecadal natural climate variability in global surface temperatures by subtracting, from the observed temperature evolution, multimodel ensemble mean based on the

Abstract Decadal fluctuations in the climate of the North Atlantic–European region may be influenced by interactions between the atmosphere and the Atlantic Ocean, possibly as part of a coupled
