TLDR
In this paper, the authors used tree-ring records from eastern North America and northwestern Europe to develop the first reconstruction of the winter North Atlantic Oscillation (NAO) and found that the reconstructed series spans the interval AD 1701-1980 and explains 41% of the variance in the NAO over the AD 1874-1980 calibration period.Abstract:
Tree-ring records, six from eastern North America and four from northwestern Europe, are used to develop the first reconstruction of the winter North Atlantic Oscillation (NAO) The reconstructed series spans the interval AD 1701-1980 and explains 41%, of the variance in the NAO over the AD 1874-1980 calibration period The reconstruction also captures the spectral properties of this index, suggesting that the oscillatory character of the NAO is a long-term feature of the North Atlantic climate systemread more

Observed climate variability and change
TL;DR: In this paper, the authors emphasise that the certainty of conclusions that can be drawn about climate from observations depends critically on the availability of accurate, complete and consistent series of observations.

Climate over past millennia
Philip Jones,Michael E. Mann +1 more
TL;DR: This paper reviewed evidence for climate change over the past several millennia from instrumental and high-resolution climate "proxy" data sources and climate modeling studies and concluded that late 20th century warmth is unprecedented at hemispheric and, likely, global scales.

TL;DR: Variability of the North Atlantic Oscillation and the Tropical Atlantic dominate the climate of North Atlantic sector, the underlying ocean and surrounding continents on interannual to decadal time scales as mentioned in this paper.

TL;DR: This work identifies issues related to: (i) spatial variation; (ii) seasonality; (iii) non–stationarity; (iv) nonlinearity; and (v) lack of correlation in the relationship between global and local climate.

Strong coherence between solar variability and the monsoon in Oman between 9 and 6 kyr ago
U. Neff,Stephen J. Burns,Stephen J. Burns,Augusto Mangini,Manfred Mudelsee,Dominik Fleitmann,Albert Matter +6 more
TL;DR: A high-resolution record of oxygen isotope variations, for the period from 9.6 to 6.1 kyr before present, in a Th–U-dated stalagmite from Oman suggests that one of the primary controls on centennial- to decadal-scale changes in tropical rainfall and monsoon intensity during this time are variations in solar radiation.

Regression and time series model selection in small samples
TL;DR: In this article, a bias correction to the Akaike information criterion, called AICC, is derived for regression and autoregressive time series models, which is of particular use when the sample size is small, or when the number of fitted parameters is a moderate to large fraction of the sample sample size.

Teleconnections in the Geopotential Height Field during the Northern Hemisphere Winter
John M. Wallace,David S. Gutzler +1 more
TL;DR: In this paper, a review of existing literature on the subject reveals the existence of at least four such patterns: the North Atlantic and North Pacific Oscillations identified by Walker and Bliss (1932), a zonally symmetric seesaw between sea level pressures in polar and temperature latitudes, first noted by Lorenz (1951), and what we will refer to as the Pacific/North American pattern, which has been known to operational long-range forecasters in this country since the 1950's.

An oscillation in the global climate system of period 65–70 years
TL;DR: In this article, the authors apply singular spectrum analysis to four global-mean surface temperature records and identify a temperature oscillation with a period of 65-70 years over the North Atlantic Ocean and its bounding Northern Hemisphere continents.

Singular-spectrum analysis: a toolkit for short, noisy chaotic signals
TL;DR: Singular spectrum analysis (SSA) is used in this article to estimate the lagged-covariance matrix of the processes studied, which is the basis of SSA.
