The “excess chloride” record from the Greenland GISP2 Ice Core provides two startling outlier observations that echo the underlying 700 year rhythm of the Lawler Events.
J H L Lawler observed that all major empires rise and collapse every 700 years and that there is a complete collapse of civilization every 1400 years.
The “excess chloride” outliers from the Greenland GISP2 Ice Core align well with [both] the Heinson Horizon and the start of the Little Ice Age in the δO18 record extracted from an Old Japanese Cedar.
The extensive δO18 record from this Old Japanese Cedar provides an opportunity to evaluate a complete Lawler Cycle over it’s [hypothesised] 1,400 years.
The δO18 record from the Old Japanese Cedar suggests there is a repeating pattern of Little Ice Ages that recur [roughly] every 1,437 years with each Little Ice Age lasting for about 135 years.
The dramatic onset of the mid-cycle Lawler Event [around 916 AD] is very close to the Heinson Horizon and heralded a [roughly] 135 year period of cooler weather.
Using the above sources it appears the last Lawler Event began [roughly] between 1637 and 1647 and these dates align well with the onset of the Maunder Minimum.
The Maunder Minimum, also known as the “prolonged sunspot minimum”, is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time.
There is still a very poor understanding of the correlation between low sunspot activity and cooling temperatures.
During the period 1645–1715, in the middle of the Little Ice Age, there was a period of low solar activity known as the Maunder Minimum.
Although the mainstream has a “very poor understanding” of the cooling during the Maunder Minimum [and the Little Ice Age] there is evidence suggesting an increase in meteor activity may have exacerbated the winter extremes.
The historical records of meteor observations from Korea might explain the Little Ice Age because of their variable density banding [over the centuries] and their seasonal variations which markedly peak during the last quarter of the year.

Using the last Lawler Event as a filter for the interpretation of history is an interesting exercise because [amongst other things] it suggests the last Lawler Event had a more profound impact in the Eastern hemisphere.
In the Deccan Famine of 1630–1632 some 2 million Indians had died. The famine was the result of three consecutive staple crop failures, leading to intense hunger, disease, and displacement in the region.
This famine remains one of the most devastating famines in the history of India, and was the most serious famine to occur in the Mughal Empire.
The second Manchu invasion of Korea occurred in 1636, when the Manchu Qing Empire defeated Korea’s Joseon dynasty, forcing it to recognize the Qing Empire as the rightful dynasty of China, instead of the previous Ming Dynasty.

Mount Parker, locally known as Melibengoy, is a stratovolcano on Mindanao island in the Philippines (6°06.8′ N, 124°53.5′ E).
The elevation is given as 1,784 meters by some sources and as 1,824 meters by others.
The volcano has an elevation of and a base diameter of 40 km.
It has a 2.9-km-wide caldera with steep walls that rise 200-500m above the lake that is now called Lake Maughan.
Mount Parker is believed to have erupted thrice over the past 3,800 years, the last one on January 4, 1641.
The 1641 eruption caused the formation of the crater lake.
The Ming dynasty was the ruling dynasty of China for 276 years (1368–1644) following the collapse of the Mongol-led Yuan dynasty.
In 1640, masses of Chinese peasants who were starving, unable to pay their taxes, and no longer in fear of the frequently defeated Chinese army, began to form into huge bands of rebels.
The Chinese military, caught between fruitless efforts to defeat the Manchu raiders from the north and huge peasant revolts in the provinces, essentially fell apart.
Unpaid and unfed, the army was defeated by Li Zicheng – now self-styled as the Prince of Shun – and deserted the capital without much of a fight.
On 26 May 1644, Beijing fell to a rebel army led by Li Zicheng when the city gates were treacherously opened from within.
During the turmoil, the last Ming emperor hanged himself on a tree in the imperial garden outside the Forbidden City.
The Chongzhen Emperor (6 February 1611 – 25 April 1644), personal name Zhu Youjian, was the 16th and last emperor of the Ming dynasty in China, reigning from 1627–1644.
In the Western hemisphere the last Lawler Event ushered in the Wars of the Three Kingdoms during which [for a change] the British fought amongst themselves.
The Wars of the Three Kingdoms formed an intertwined series of conflicts that took place in England, Ireland and Scotland between 1639 and 1651.
The English Civil War has become the best-known of these conflicts and included the execution of the kingdoms’ monarch, Charles I, by the English parliament in 1649.
But the most curious aspect of the last Lawler Event is that it’s arrival was immediately preceded by the Gregorian calendar and the Scientific Renaissance.
The Gregorian calendar, also called the Western calendar and the Christian calendar, is internationally the most widely used civil calendar.
It is named for Pope Gregory XIII, who introduced it in 1582.
While its dates are disputed, the publication in 1543 of Nicolaus Copernicus’s De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) is often cited as marking the beginning of the scientific revolution.
A first phase of the scientific revolution, focused on the recovery of the knowledge of the ancients, can be described as the Scientific Renaissance and is considered to have ended in 1632 with publication of Galileo’s Dialogue Concerning the Two Chief World Systems.
Johannes Kepler (December 27, 1571 – November 15, 1630) was a German mathematician, astronomer, and astrologer.
A key figure in the 17th century scientific revolution, he is best known for his laws of planetary motion, based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy.
Galileo Galilei (15 February 1564 – 8 January 1642), was an Italian astronomer, physicist, engineer, philosopher, and mathematician who played a major role in the scientific revolution during the Renaissance.
Galileo has been called the “father of observational astronomy”, the “father of modern physics”, and the “father of science”.
TREPIDATION (from Lat. trepidare, to tremble), a term meaning, in general, fear or trembling, but used technically in astronomy for an imagined slow oscillation of the ecliptic, having a period of 7000 years, introduced by the Arabian astronomers to explain a supposed variation in the precession of the equinoxes.

Therefore, it’s just possible, that a series of Great Comets helped to inspire the Scientific Renaissance whilst [simultaneously] heralding the approach of the last Lawler Event.
The Great Comet of 1556 is a famous comet that first appeared in February 1556.
Its apparent diameter was equal to half that of the Moon, and the tail resembled “the flame of a torch agitated by the wind,” – an expression doubtless referring to the coruscation which are sometimes visible in the tails of comets.
Cornelius Gemma (the son of Gemma Frisius) says, the head of the comet, when it first appeared, was fully as large as Jupiter; its color resembled that of Mars.
On the other hand, it’s also possible that the timing of the Scientific Renaissance and the subsequent Lawler Event are purely coincidental.
I guess it all depends upon how comfortable you are with coincidences.
