An oscillation in the global climate system of period 65–70 years

  title={An oscillation in the global climate system of period 65–70 years},
  author={M. Schlesinger and N. Ramankutty},
IN addition to the well-known warming of ∼0.5 °C since the middle of the nineteenth century, global-mean surface temperature records1–4display substantial variability on timescales of a century or less. Accurate prediction of future temperature change requires an understanding of the causes of this variability; possibilities include external factors, such as increasing greenhouse-gas concentrations5–7 and anthropogenic sulphate aerosols8–10, and internal factors, both predictable (such as El Ni… Expand
A century and a half of change in the climate of the NE Pacific
A long-range forecast suggests that the BDO and VLF oscillations peaked in 1989 and are currently in a cooling phase, Consequently, coastal temperatures should moderate for the rest of this century. Expand
The role of Atlantic Multi-decadal Oscillation in the global mean temperature variability
The global mean 1900–2015 warming simulated by 42 Coupled Models Inter-comparison Project, phase 5 (CMIP5) climate models varies between 0.58 and 1.70 °C. The observed warming according to the NASAExpand
Low‐frequency oscillations in temperature‐Proxy records and implications for recent climate change
The global-mean surface temperature has inherent variability on all time scales. Distinguishing natural climatic variability from the observed ∼0.5°C warming since the mid nineteenth century isExpand
Quasiperiodic climate variability with a period of 50–80 years: Fourier analysis of measurements and Earth System Model simulations
We examine an oscillation of global mean temperature with a period of about two thirds of a century. We find evidence for the oscillation both in the instrumental temperature record and in an EarthExpand
How would global-mean temperature change in the 21st century?
The time series of HadCRUT3 global-mean surface air temperature (GSAT) anomaly, Pacific decadal oscillation (PDO) index, and the equatorial Pacific sea surface temperature (SST) were utilized, andExpand
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.

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-yearExpand
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.

Secular and multidecadal warmings in the North Atlantic and their relationships with major hurricane activity
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 surfaceExpand
Is the recently reported 65‐ to 70‐year surface‐temperature oscillation the result of climatic noise?
In a recent paper (Schlesinger and Ramankutty, 1994) we reported finding a 65- to 70-year oscillation in each of the four records of observed global-mean surface temperature. We also found that theExpand


Do bidecadal oscillations exist in the global temperature record?
MODELS predict1–3 that increasing atmospheric concentrations of greenhouse gases will result in an increase in the global mean temperature over the next few decades and beyond. It is thereforeExpand
Interdecadal oscillations and the warming trend in global temperature time series
THE ability to distinguish a warming trend from natural variability is critical for an understanding of the climatic response to increasing greenhouse-gas concentrations. Here we use singularExpand
Natural variability of the climate system and detection of the greenhouse effect
GLOBAL mean temperatures show considerable variability on all timescales. The causes of this variability are usually classified as external or internal1, and the variations themselves may be usefullyExpand
Climate spectra and detecting climate change
Part of the debate over possible climate changes centers on the possibility that the changes observed over the previous century are natural in origin. This raises the question of how large a changeExpand
Interdecadal Variations in North Atlantic Sea Surface Temperature and Associated Atmospheric Conditions
Abstract Evidence is presented for a distinct Pattern Of ocean-atmosphere relationship associated with interdecadal variability in the North Atlantic region. Using a century of surface marineExpand

Interpentadal variability of temperature and salinity at intermediate depths of the North-Atlantic O
We have composited historical hydrographic observations for the world ocean for two pentads, 1955–1959 and 1970–1974, and have objectively analyzed these data for the purpose of studying the temporalExpand
Solar cycle length, greenhouse forcing and global climate
THE recent rise in global-mean surface air temperature is widely thought to be the result of increasing atmospheric concentrations of greenhouse gases1–3, but there are discrepancies between theExpand
