We investigate whether or not the decadal and multi-decadal climate oscillations have an astronomical origin. Several global surface temperature records since 1850 and records deduced from the orbits of the planets present very similar power spectra. Eleven frequencies with period between 5 and 100 years closely correspond in the two records. Among them, large climate oscillations with peak-to-trough amplitude of about 0.1 and 0.251C, and periods of about 20 and 60 years, respectively, are… Expand
On the sixty-year periodicity in climate and astronomical series
In a recent article by Scafetta, 2010, the author investigates whether or not the decadal and multi-decadal climate oscillations have an astronomical origin. In particular, the author note thatExpand
On the astronomical origin of the Hallstatt oscillation found in radiocarbon and climate records throughout the Holocene
Abstract An oscillation with a period of about 2100–2500 years, the Hallstatt cycle, is found in cosmogenic radioisotopes (14C and 10Be) and in paleoclimate records throughout the Holocene. ThisExpand
A shared frequency set between the historical mid-latitude aurora records and the global surface temperature
Abstract Herein we show that the historical records of mid-latitude auroras from 1700 to 1966 present oscillations with periods of about 9, 10–11, 20–21, 30 and 60 years. The same frequencies areExpand
Signals from the planets, via the Sun to the Earth
The best method for identification of planetary forcing of the Earth's climate is to investigate pe- riodic variations in climate time series. Some natural frequencies in the Earth climate systemExpand
Testing an astronomically based decadal-scale empirical harmonic climate model versus the IPCC (2007) general circulation climate models
Abstract We compare the performance of a recently proposed empirical climate model based on astronomical harmonics against all CMIP3 available general circulation climate models (GCM) used by theExpand
Evidence for two abrupt warming events of SST in the last century
We have recently suggested that the warming in the sea surface temperature (SST) since 1900, did not occur smoothly and slowly, but with two rapid shifts in 1925/1926 and 1987/1988, which are moreExpand
Reconstruction of the Interannual to Millennial Scale Patterns of the Global Surface Temperature
Climate changes are due to anthropogenic factors, volcano eruptions and the natural variability of the Earth’s system. Herein the natural variability of the global surface temperature is modeledExpand
Solar and Planetary Oscillation Control on Climate Change: Hind-Cast, Forecast and a Comparison with the Cmip5 Gcms
Global surface temperature records (e.g. HadCRUT4) since 1850 are characterized by climatic oscillations synchronous with specific solar, planetary and lunar harmonics superimposed on a backgroundExpand
Discussion on the spectral coherence between planetary, solar and climate oscillations: a reply to some critiques
During the last few years a number of works have proposed that planetary harmonics regulate solar oscillations. Also the Earth’s climate seems to present a signature of multiple astronomicalExpand
Evidences for a quasi 60-year North Atlantic Oscillation since 1700 and its meaning for global climate change
The North Atlantic Oscillation (NAO) obtained using instrumental and documentary proxy predictors from Eurasia is found to be characterized by a quasi 60-year dominant oscillation since 1650. ThisExpand


Possible forcing of global temperature by the oceanic tides.

It is proposed that the dissipation of extreme tides increases vertical mixing of sea water, thereby causing episodic cooling near the sea surface, which explains near-decadal temperature periodicities and may also apply to variability in temperature and climate on other times-scales. Expand

It is proposed that strong tidal forcing causes cooling at the sea surface by increasing vertical mixing in the oceans by resonances in the periodic motions of the earth and moon. Expand
A large discontinuity in the mid-twentieth century in observed global-mean surface temperature
It is argued that the abrupt temperature drop in 1945 is the apparent result of uncorrected instrumental biases in the sea surface temperature record, and Corrections for the discontinuity are expected to alter the character of mid-twentieth century temperature variability but not estimates of the century-long trend in global-mean temperatures.

The decadal fluctuations in the Earth's rotation and in the climate characteristics
Close correlations are found between the decades-long variations in the length of the day (LOD), variations in the rate of the westward drift of the geomagnetic eccentric dipole, and variations inExpand
The "Sun - climate" relationship. II. The "cosmogenic" beryllium and the middle latitude aurora.
In Paper I we pointed out that the subcenturial climate cycle with duration of 50-70 years could have solar reason. The argument was the existence of statistically signifi- cant respective cycle inExpand
On the 60-year signal from the core
The decadal variation in the length of day and in the Earth's magnetic field is analyzed by empirical mode decomposition (EMD). The existence of a periodicity of about 60-years in the Earth's angularExpand
Amplifying the Pacific Climate System Response to a Small 11-Year Solar Cycle Forcing
Two mechanisms, the top-down stratospheric response of ozone to fluctuations of shortwave solar forcing and the bottom-up coupled ocean-atmosphere surface response, are included in versions of three global climate models, with either mechanism acting alone or both acting together. Expand
Celestial driver of Phanerozoic climate
Atmospheric levels of CO2 are commonly assumed to be a main driver of global climate. Independent empirical evidence suggests that the galactic cosmic ray flux (CRF) is linked to climate variability.Expand

Cosmic Rays and Climate
Among the most puzzling questions in climate change is that of solar-climate variability, which has attracted the attention of scientists for more than two centuries. Until recently, even theExpand
