Although El Niño and La Niña are the largest single sources of global interannual climate variability, climate shifts on longer time scales than El Niño's 2 to 7 years are also drawing the attention of researchers. On multidecadal time scales of 40 to 80 years, a restless North Atlantic seems to be at work, alternately countering and enhancing humankind's alterations of climate. The evidence for this is turning up in such records as tree rings, ice cores, and corals.

Atlantic Ocean Forcing of North American and European Summer Climate
TLDR
New evidence is presented that basin-scale changes in the Atlantic Ocean, probably related to the thermohaline circulation, have been an important driver of multidecadal variations in the summertime climate of both North America and western Europe.
Multidecadal Tendencies in ENSO and Global Temperatures Related to Multidecadal Oscillations
Perlwitz etal (2009) used computer model suites to contend that the 2008 North American cooling was naturally induced as a result of the continent's sensitivity to widespread cooling of the tropical
Effects of solar forcing and North Atlantic oscillation on the climate of continental Scandinavia during the Holocene
Abstract 10,000-year-long varved sediment records from lakes Nautajarvi and Korttajarvi, Finland provide evidence of climate and environment oscillations at multi-decadal to millennial timescales. We
A signature of persistent natural thermohaline circulation cycles in observed climate
[1] Analyses of global climate from measurements dating back to the nineteenth century show an ‘Atlantic Multidecadal Oscillation’ (AMO) as a leading large-scale pattern of multidecadal variability
Amplification of the Atlantic Multidecadal Oscillation associated with the onset of the industrial-era warming
TLDR
An annually resolved coralline algal time series from the northwest Atlantic Ocean that exhibits multidecadal variability extending back six centuries is presented and it is argued that changes are associated with a regional climate reorganization involving an amplification of the AMO that coincided with onset of the industrial-era warming.
The role of the Atlantic Multidecadal Oscillation on medieval drought in North America: Synthesizing results from proxy data and climate models
article i nfo During medieval times (900-1300 AD; henceforth MT), persistent drought ('megadrought') was a ubiquitous feature for much of North America. To better understand the mechanisms for these
Asymmetric impact of Atlantic Multidecadal Oscillation on El Niño and La Niña characteristics
The long-lasting cold surface conditions of North Atlantic, i.e., the negative phase of Atlantic Multidecadal Oscillation (AMO), can intensify the El Nino–Southern Oscillation through the enhanced
Forced and Internal Twentieth-Century SST Trends in the North Atlantic*
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.
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 and
North Atlantic multidecadal to centennial variability in a model and a marine proxy dataset
Variability on decadal and longer timescales is of great interest in climate research due to it’s socio-economic impacts, potential for predictability and masking of anthroprogenic global warming.
