Analysis of recent literature finds weaknesses in arguments to the effect that the Atlantic multidecadal oscillation (AMO)—roughly 50–90 year fluctuations in North Atlantic sea surface temperatures—is externally forced by anthropogenic aerosols and greenhouse gases rather than an internal climate mode, plus indications from other sources that the contrary may be true. We are led to the conclusion that the AMO is probably comprised of both natural and anthropogenic forcing in ways that preclude…

Contribution of Atlantic and Pacific Multidecadal Variability to Twentieth-Century Temperature Changes
AbstractRecent studies have suggested that significant parts of the observed warming in the early and the late twentieth century were caused by multidecadal internal variability centered in the
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
Multidecadal-to-centennial SST variability in the MPI-ESM simulation ensemble for the last millennium
We assess the responses of North Atlantic, North Pacific, and tropical Indian Ocean Sea Surface Temperatures (SSTs) to natural forcing and their linkage to simulated global surface temperature (GST)
Key role of the Atlantic Multidecadal Oscillation in 20th century drought and wet periods over the Great Plains
[1] The Great Plains of North America are susceptible to multi-year droughts, such as the 1930s ‘Dust Bowl’. The droughts have been linked to SST variability in the Pacific and Atlantic basins. This
Atlantic Multidecadal Oscillation (AMO) and sea surface temperature in the Bay of Biscay and adjacent regions
The sea surface temperature (SST) variability of the Bay of Biscay and adjacent regions (1854–2010) has been examined in relation to the evolution of the Atlantic Multidecadal Oscillation (AMO), a
Future Impact of Differential Interbasin Ocean Warming on Atlantic Hurricanes
Global climate model simulations forced by future greenhouse warming project that the tropical North Atlantic (TNA) warms at a slower rate than the tropical Indo-Pacific in the twenty-first century,
Atlantic hurricane activity during the last millennium
The results corroborate evidence for the increasing trend of hurricane activity during the Industrial Era; however, it is shown that contemporary activity has not exceeded the range of natural climate variability exhibited during the last millennium.
Atmospheric response to the North Atlantic Ocean variability on seasonal to decadal time scales
The NCEP twentieth century reanalyis and a 500-year control simulation with the IPSL-CM5 climate model are used to assess the influence of ocean-atmosphere coupling in the North Atlantic region at
An attempt to deconstruct the Atlantic Multidecadal Oscillation
The link between the Atlantic Multidecadal Oscillation (AMO) and low-frequency changes of the Atlantic Meridional Overturning Circulation (AMOC) is investigated in three historical and five control
Corals record persistent multidecadal SST variability in the Atlantic Warm Pool since 1775 AD
[1] Accurate low-latitude sea surface temperature (SST) records that predate the instrumental era are needed to put recent warming in the context of natural climate variability and to evaluate the


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

North Atlantic sea surface temperatures for 1856-1999 contain a 65-80 year cycle with a 0.4 C range, referred to as the Atlantic Multidecadal Oscillation (AMO) by Kerr (2000). AMO warm phases
Reconstructing, Monitoring, and Predicting Multidecadal-Scale Changes in the North Atlantic Thermohaline Circulation with Sea Surface Temperature
Sea surface temperature (SST) observations in the North Atlantic indicate the existence of strong multidecadal variability with a unique spatial structure. It is shown by means of a new global

Pacific and Atlantic Ocean influences on multidecadal drought frequency in the United States
Should the current positive AMO (warm North Atlantic) conditions persist into the upcoming decade, it is suggested two possible drought scenarios that resemble the continental-scale patterns of the 1930s and 1950s drought.
