During the Little Ice Age (LIA; covering approximately the fifteenth through the eighteenth centuries), northern South America experienced about 10 percent more rainfall than during the twentieth century, according to Reuter et al.
The authors analyzed two new records of oxygen isotopes (which track precipitation levels) from cave formations in northeastern Peru. They attribute the higher rainfall in northern South America during the LIA to cooler spring sea surface temperatures in the tropical North Atlantic.
Furthermore, the authors note that some studies have shown that during the twentieth century, a significant amount of rainfall variability in northern South America was related to the El Niño-Southern Oscillation (ENSO), with higher rainfall occurring during La Niña conditions.
However, the authors determine that the ENSO was probably not as significant an influence on rainfall during that time period as it is now.
The authors suggest that the results point to a need to reevaluate some ideas about hydroclimate change over South America during the past millennia.
The research is published in Geophysical Research Letters.

Then he married Grace Kelly and moved Monaco to Europe. History is cool.
:’D
I am shocked that these people do not read history, shocked. Starting with the Great Famine of 1314 thru 1321, It was cold and wet for 500 hundred years in Europe, why would SA get a pass?
Did they move Mt. Ranier? :D
Little Ice Age Ping!
Well, the alleged "climatologists" who authored the Hockey Stick sure didn't read it.
This is from Wiki and fairly balanced.

The Black Death also struck during the Little Ice Age. Cold is not friendly to life.
If I remember right William McNeil stated something similar in "Plagues and People."
