Younger-Dryas–“The Underlying Reality”

By Ronald G. Messick

It is commonly accepted that starting in about 13,000 (BCE), the Earth experienced three major climatic catastrophes–one after another; i.e. (Bölling-Allerød, Younger-Dryas and Pre-boreal warming periods). They are described herein as catastrophic because that 1-2-3 punch annihilated a significant percentage of life on Earth.

The most precise records of late Pleistocene climate changes are the ice cores of the Greenland Ice Sheet Project (GISP) and the Greenland Ice Core Project (GRIP). These cores are especially important because the ages of the ice at various levels in the core have been measured by counting annual layers in the ice, giving a very accurate chronology of climatic fluctuations determined by measurement of annual layers.

The illustration below flags the timing associated with those three events based on temperature data from Cuffy and Clow (1997) which was modified by Alley (2000). A comparison of the two different approaches shows essential agreement.


What follows is a description of the three events:

  • 1. The Bölling-Allerød interstadial was a sudden, intense, climatic warming period that caused dramatic melting of large Ice Age ice sheets that covered Canada and the northern U.S., all of Scandinavia, and much of northern Europe and Russia. Sea level that had been 120 m (~400 ft) lower than present rose quickly and submerged large areas of the Earth’s surface that had been dry land during the Ice Age. This warming occurred abruptly in only a few years (Steffensen et al., 2008). This warming (~12° C; ~21° F) ran from c. 12,800 to c. 10,900 (BCE). It ended abruptly with the onset of the Younger Dryas.
  • 2. The Younger-Dryas was a cold period that reduced temperatures back to near-glacial levels within a decade. It began about 10,900 (BCE) when global temperatures plunged sharply (~8°C; ~14° F), sparking a 1200-year period of glacial re-advance. Its end came abruptly with the onset of Pre-boreal warming about 9,700 (BCE).
  • 3. Pre-boreal warming began about 9,700 (BCE) when, almost overnight, global temperatures rose parabolically (~12° C; ~21° F), marking the end of the Younger Dryas cold period and the end of the Pleistocene Ice Age. The peak rise in temperatures was reached about 9,500 (BCE). 

The narrative of the events was provided by Dr. Don J. Easterbrook

There has been an abundance of speculation as to the cause of these events (even a book or two) but no one has offered an explanation that ties all three of these extreme climate events together. Instead of simply classifying these events as random acts of nature, such as meteor strikes, we argue that all three events have a physical cause which would imply that these types of events may be predictable.

The proposed mechanism: “Ultra-low-frequency emanations from the Sun”–a concept that is firmly rooted in science. The challenge is to identify the emanations that impact long-term climate conditions here on Earth.

Two possible harmonic frequencies have been identified. The pattern below, overlayed on top of the temperature data, is the manifestation of one of the two frequencies.


The objective is to identify wave structures that are synchronous with sudden and extreme shifts in climate such as those that had delivered the subject 1, 2, 3-punch. The wave structures themselves represent the locked potential contained within two opposing magnetic fields.

To show the degree with which peaks and throughs align themselves with key temperature turning-points, the peaks are flagged with a verticle red arrow and the throughs are identified with a red rectangle.


Correlations between historical events and wave propagation is hard to deny. Even ardent skeptics will agree that something is going on here besides chance. But, what is even more exciting is that these correlations continue right up to the present (see exhibits below).

In the following illustration, a second wave structure is overlayed on the first wave with its peaks and throughs identified as was done with wave one. The results are astonishing.


In the six-thousand-year period between 14,000 and 8,000 BCE, every major climate shift was precipitated by either one of the peaks or throughs–along with a super-majority of the major climate shifts that have occurred since.

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. All electromagnetic waves travel at the speed of light (c = 3.0 × 108 m/s) in a vacuum. There seem to be no upper and lower limits to the frequency or wavelength of electromagnetic waves and no gaps in the spectrum.

However, electromagnetic waves have been observed with incredibly long wavelengths — these waves are known as ultra low frequency (ULF) waves, or micropulsations. Since frequency and wavelength are inversely proportional (v = fλ, for electromagnetic waves c = fλ), the name “ultra low frequency” is equivalent to “ultra long wavelength” — although nobody refers to them as such. The range of wavelengths which refer to ULF waves is disputable, and different sources cite different ranges. The consensus seems to be that the wavelength of the longest electromagnetic wave is in the range from 106 to 1011 M. However, it is not impossible to discover a wave with a wavelength approaching infinity.

ULF waves seem to have extraterrestrial sources (they seem to “result from interactions between plasma emitted from the sun (solar wind) and the Earth’s [magnetic] field”). Geomagnetic pulsations were first observed by Balfour Stewart in 1859, and he published his findings in 1861. Some people are interested in the sounds produced by ULF waves, VLF waves (very low frequency), and ELF waves (extremely low frequency). There is also speculation and research into the possibility that micropulsations may have an affect on people’s health and on women’s menstrual cycles.

Abstract One of the most important issues in space physics is to identify the dominant processes that transfer energy from the solar wind to energetic particle populations in Earth’s inner magnetosphere. Ultra-low-frequency (ULF) waves are an important consideration as they propagate electromagnetic energy over vast distances with little dissipation and interact with charged particles via drift resonance and drift-bounce resonance. ULF waves also take part in magnetosphere-ionosphere coupling and thus play an essential role in regulating energy flow throughout the entire system. This review summarizes recent advances in the characterization of ULF Pc3-5 waves in different regions of the magnetosphere, including ion and electron acceleration associated with these waves.’s_magnetosphere

The physical processes of transferring electromagnetic energy from sun to the earth is referred to as Solar – Terrestrial system. It involves terrestrial atmosphere, the outer part of geomagnetic field, and the solar events, which influence them.

Earth’s magnetic shield, which protects against harmful radiation from the sun and more distant sources, is full of ultra-low frequency (ULF) waves. These waves transfer energy from outside Earth’s magnetic shield to regions inside it. And, they play a key role in creating the impacts of space weather—including geomagnetic storms. The frequency of those waves ranges from fractions of a millihertz (MHz) up to just 1 hertz (Hz). One-thousand MHz equals 1 Hz—a much lower frequency than the range of human hearing.

To further investigate this coupling mechanism, we propose another exogenous source to be analyzed which is cosmic ray. In this study, the investigation on possible relationship between geomagnetic ULF pulsation and seismicity due to exogenous parameters has been focused. Unlike other frequency range, ULF waves can propagate

through the crust and reach the earth surface, thus produce reliable precursors to large impending earthquakes.
