Although the period of the “Little Ice Age” is a scientific reconstruction it covers a period when there was a significant down turn in climate, compared to the present era. These are classified into four periods when the climate deteriorated significantly. This deterioration was not only cooler and wetter on average but vastly more erratic and these are prime ingredients for famine. These erratic periods were the Wolf, Sporer, Maunder and Dalton minima’s(2) respectively.
They followed a period known as the “Medieval maximum” which some contend was warmer than the present period(3). This earlier warm time was generally a period of expansion and prosperity for civilizations(4).
