“…Our results indicate that the Mediterranean climate during the MSC peak was characterized by climatic oscillations similar to those observed during the past few centuries, likely regulated by astronomical cycles related to the Moon and to the natural oscillations of the Sun and the heliosphere (Scafetta 2010;2012a, 2012b, 2012c, 2012d, Wang et al 2012. Evaporite deposition was caused by precipitation at the pycnocline interface induced by intense evaporation during the driest season and hampered by water-mass dilution related to precipitation and fluvial runoff increase during the wet season (Fig.…”

“…The periodicities recognized in our study resemble the ones associated to the QuasiBiennial Oscillation, the El Niñ o Southern Oscillation, the sunspotnumber solar cycle and, interestingly, the 9 year periodicity related to a lunisolar tidal cycle. All of these represent the main climate forcing mechanisms that regulated temperature and precipitation in the Mediterranean in the past 500 years (Camuffo et al 2010;Scafetta 2010Scafetta , 2012aWang et al 2012). We suggest that during the MSC, at least during the insolation minima when evaporites precipitated, the Mediterranean did not have a constant hydrological budget but was rather characterized by a highly dynamic climate.…”

“…This decadal cycle, which is quite evident in several temperature records, can be related to major solar oscillations and lunisolar tidal cycles, which can modulate ocean currents and the albedo through a direct forcing of the cloud system (Scafetta 2010, 2012a, 2012b. Thus, numerous astronomical oscillations would influence climate, as is already known to happen for tidal dynamics (Ehret 2008;Wang et al 2012). Variations in the ocean circulation are well known to drive and influence the global climate and would influence Europe and the Mediterranean region as well.…”

The deposition of varved sedimentary sequences is usually controlled by climate conditions. The study of two late Miocene evaporite successions (one halite and the other gypsum) consisting of annual varves has been carried out to reconstruct the paleoclimatic and paleoenvironmental conditions existing during the acme of the Messinian salinity crisis, , 6 Ma, when thick evaporite deposits accumulated on the floor of the Mediterranean basin. Spectral analyses of these varved evaporitic successions reveal significant periodicity peaks at around 3-5, 9, 11-13, 20-27 and 50-100 yr. A comparison with modern precipitation data in the western Mediterranean shows that during the acme of the Messinian salinity crisis the climate was not in a permanent evaporitic stage, but in a dynamic situation where evaporite deposition was controlled by quasi-periodic climate oscillations with similarity to modern analogs including Quasi-Biennial Oscillation, El Niño Southern Oscillation, and decadal to secular lunar-and solar-induced cycles. Particularly we found a significant quasi-decadal oscillation with a prominent 9-year peak that is commonly also found in modern temperature records and is present in the contemporary Atlantic Multidecadal Oscillation (AMO) index and Pacific Decadal Oscillation (PDO) index. These cyclicities are common to both ancient and modern climate records because they can be associated with solar and solar-lunar tidal cycles.During the Messinian the Mediterranean basin as well as the global ocean were characterized by different configurations than at present, in terms of continent distribution, ocean size, geography, hydrological connections, and ice-sheet volumes. The recognition of modern-style climate oscillations during the Messinian suggests that, although local geographic factors acted as pre-conditioning factors turning the Mediterranean Sea into a giant brine pool, external climate forcings, regulated by solarlunar cycles and largely independent from local geographic factors, modulated the deposition of the evaporites.

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 astronomical harmonics. Herein I address some critiques claiming that planetary harmonics would not appear in the data. I will show that careful and improved analysis of the available data do support the planetary theory of solar and climate variation also in the critiqued cases. In particular, I show that: (1) high-resolution cosmogenic 10Be and 14C solar activity proxy records both during the Holocene and during the Marine Interglacial Stage 9.3 (MIS 9.3), 325-336 kyear ago, present four common spectral peaks (confidence level 95 %) at about 103, 115, 130 and 150 years (this is the frequency band that generates Maunder and Dalton like grand solar minima) that can be deduced from a simple solar model based on a generic non-linear coupling between planetary and solar harmonics; (2) time-frequency analysis and advanced minimum variance distortion-less response (MVDR) magnitude squared coherence analysis confirm the existence of persistent astronomical harmonics in the climate records at the decadal and multidecadal scales when used with an appropriate window lenght (L=110 years) to guarantee a sufficient spectral resolution to solve at least the major astronomical harmonics. The optimum theoretical window length deducible from astronomical considerations alone is, however, L=178.4 years because the planetary frequencies are harmonics of such a period. However, this length is larger than the available 164-year temperature signal. Thus, the best coherence test can be currently made only using a single window as long as the temperature instrumental record and comparing directly the temperature and astronomical spectra as done in Scafetta (J. Atmos. Sol. Terr. Phys. 72(13):951-970, 2010) and reconfirmed here. The existence of a spectral coherence between planetary, solar and climatic oscillations is confirmed at the following periods: 5.2 year, 5.93 year, 6.62 year, 7.42 year, 9.1 year (main lunar tidal cycle), 10.4 year (related to the 9.93-10.87-11.86 year solar cycle harmonics), 13.8-15.0 year, 20 year, 30 year and 61 year, 103 year, 115 year, 130 year, 150 year and about 1000 year. This work responds to the critiques of Cauquoin et al. (Astron. Astrophys. 561:A132, 2014), who ignored alternative planetary theories of solar variations, and of Holm (J. Atmos. Sol. Terr. Phys. 110-111:23-27, 2014a), who used inadequate physical and time frequency analyses of the data

“…Superimposed on these long-term trends of minima and maxima are short-term fluctuations caused by the Schwabe cycle [8], [9]. Furthermore, other studies suggest that the climate and atmospheric oscillations, such as the Pacific Decadal Oscillation (PDO), the Atlantic Multidecadal Oscillation (AMO) and El Niño Southern Oscillation (ENSO), are synchronized to the natural oscillations of the Solar System, which are driven by the movements of the planets around the Sun and lunar gravitational tides [7], [10]- [12]. In addition, Chambers et al [13] identified multi-decadal oscillations of about 60 years in most of the ocean tide gauges examined, which are believed to be related to wind forcing and current variations [14].…”

Sea Levels in a Changing Climate

ABSTRACT:The rise of sea levels could have devastating consequences for coastal settlements, and it can easily be one of the most critical effects of climate change. Thus, all factors affecting sea levels need to be considered. One of the factors discussed in this paper is the natural variability of sea levels, which originates from the oscillation of the planets and solar activity. The effect of the Sun's activity on Earth's climate has been identified since the 1800s. However, there are still many unknowns regarding the mechanisms connecting the Earth's climate to the variation in solar irradiance. Climate modelling that implements the solar sciences is a novel approach that accounts for the considerable effect that natural factors have on the climate, especially at regional level. This paper discusses the noticeable effect that planet oscillations have on the Sun's activity, which gives a very good correlation with the observed patterns in global surface temperatures, rainfall records and sea levels. In agreement with many studies that have identified a 60-year cycle in the variation of Earth's temperature, it is expected that surface temperatures will reach a trough of the cycle around 2030-2040. Furthermore, considering the influence of the Solar Inertial Motion, a solar slowdown is predicted for Solar Cycles 24 and 25, which will create a weak grand minimum. It is anticipated that this weak grand minimum will be reflected in a dampening effect of global temperatures, and a subsequent moderation in the rate of sea level rise.
