Obviously just a coincidence.. or perhaps not:
The Pacific ocean's largest known climate cycle, the Pacific Decadal Oscillation, generally follows either the negative or positive phase for periods of 20-40 years. But usually there will be a period within a broader cycle where it flips for a couple years.
This happened precisely in early 1957 and lasted until mid-1961... when the PDO moved from its long established negative phase (1946-1957) and became very positive, especially in the 1957-1959 period.
This might not be unimportant because the El Niņo of 1957-58 was the largest in 20 years at the time and disrupted the Asian monsoon. Rather than a quick turnaround, this disruption lasted for a few years. It is probably no coincidence that China's famine was so bad. The human reasons as well as the weather played a role.
Of course for the U.S. that might not be significant.. in fact because in 1957, the southern plains/Texas was emerging from its worst drought on record (far worse than the dustbowl).
