[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 in surface temperature. Yet it is not possible to determine whether these fluctuations are genuinely oscillatory from the relatively short observational record alone. Using a 1400 year climate model calculation, we are able to simulate the observed pattern and amplitude of the AMO. The results imply…

Is the thermohaline circulation changing
Analyses of ocean observations and model simulations suggest that there have been considerable changes in the thermohaline circulation (THC) during the last century. These changes are likely to be
Tracking the Atlantic Multidecadal Oscillation through the last 8,000 years
It is shown that distinct, ∼55- to 70-year oscillations characterized the North Atlantic ocean-atmosphere variability over the past 8,000 years, and that the coupling from the AMO to regional climate conditions was modulated by orbitally induced shifts in large-scale ocean- atmosphere circulation.
Climate impacts of the Atlantic Multidecadal Oscillation
[1] The Atlantic Multidecadal Oscillation (AMO) is a near-global scale mode of observed multidecadal climate variability with alternating warm and cool phases over large parts of the Northern
Multidecadal Climate Variability in Observed and Modeled Surface Temperatures
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
Amplification of the Atlantic Multidecadal Oscillation associated with the onset of the industrial-era warming
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 Atlantic Multidecadal Oscillation Inferred from the Forced Climate Response in Coupled General Circulation Models
Abstract Instrumental sea surface temperature records in the North Atlantic Ocean are characterized by large multidecadal variability known as the Atlantic multidecadal oscillation (AMO). The lack of
Due to its nonlinear dynamics and involvement in abrupt climate changes, the thermohaline circulation is a key component of the climate system. Numerical studies have shown that it is sensitive to
Subdecadal to multidecadal cycles of Late Holocene North Atlantic climate variability preserved by estuarine fossil pigments
The climate system in the North Atlantic region is complex and influenced by outside forcings as well as internal modes of the system. Modeling and observational work have suggested that a better
Non-uniform interhemispheric temperature trends over the past 550 years
The warming trend over the last century in the northern hemisphere (NH) was interrupted by cooling from ad 1940 to 1975, a period during which the southern hemisphere experienced pronounced warming.
Muted multidecadal climate variability in central Europe during cold stadial periods
During the last ice age, the Northern Hemisphere experienced a series of abrupt millennial-scale climatic changes linked to variations in the strength of the Atlantic Meridional Overturning


A tree‐ring based reconstruction of the Atlantic Multidecadal Oscillation since 1567 A.D.
[1] We present a tree-ring based reconstruction of the Atlantic Multidecadal Oscillation (AMO) which demonstrates that strong, low-frequency (60–100 yr) variability in basin-wide (0–70°N) sea surface
Global interdecadal and century-scale climate oscillations during the past five centuries
THE recognition of natural modes of climate variability is essential for a better understanding of the factors that govern climate change. Recent models suggest that interdecadal (roughly 15–35-year

A 21st-century global warming projection far exceeds the natural variability of the past 1000 years and is greater than the best estimate of global temperature change for the last interglacial.
