Let us examine what many authors have concluded about this interesting period. To begin with there is certainly no consensus over its beginning and end nor the extent of the various periods. However there seems some consensus that the Maunder minimum was the worst of the four proposed periods.
Initially, I will give a synopsis about what many authors have concluded about the dramatic weather changes of the last two thousand years and the fluctuating weather patterns that at some stages have bought human prosperity and at other times drought, reduction in population, race movements and not least, abandonment.
Firstly however let us look at a graph that a conglomeration of Ice core studies from Camp David, GISP and Antarctica tend to summarize over the last 100,000 years (see Plate 1: GISP 2 and Plate 2: SUMMIT).These are based on oxygen 18 studies (that theoretically show annual precipitation rates, ash fallout from Volcanoes and various other Isotopes that express cosmic ray activity (from the sun) and ion concentrations from other elements. My purpose in this is to show the incredibly fluctuating weather of this vast period.
