Peter Temple (Feb 5, 2017) - Dr. Raymond H. Wheeler (1892-1961) developed a clock to forecast recurring droughts, which coincided with colder climates. He found that every 170 years, the climate would turn colder and dryer, social mood would turn negative, civil wars would proliferate, and the economy would suffer from financial collapse.
Although he completed his work during the 1930s, 40s, and 50s, he was
able to accurately forecast the second half of the 20th century, based
upon the cycles that occurred over and over again like clockwork from
600 BC through today. The Drought Clock shows shorter 100 Year Cycles of cold and dry which
are compounded by the larger degree 170 Year Cycle, when they happen at
the same time. You can see that he forecast the start of a cold, dry
170 Year Cycle just before the year 2000. Cold dry periods in history have almost always led to droughts (limited
access to food), civil wars, riots, and economic recessions or
depressions [...] The 515 Year Climate Cycle is also a major Civilization Cycle where virtually everything around us changes (more details Here + HERE).
