Fossilized Pollen

In northwestern Spain, pollen analysis from 3,000 years of sediments in the Ria de Vigo shows an alternation of three relatively cold periods with three relatively warm episodes. The research team concluded that “a millennial-scale climatic cyclicity over the last 3,000 years is detected for the first time in northwest Iberia, paralleling global climatic changes recorded in North Atlantic marine records.”57

In East Africa, pollen data from the bottom of Kenya’s Lake Naivasha showed a two-century drought during the warming period from 980 to 1200.58 The lake’s water levels fell to their lowest point in 1,000 years, while the vegetation shifted strongly away from woody plant species toward more grasses.

"The composition of stalagmites from South Africa vary with the 1,500-year cycle."

In Peru, declining amounts of fossilized pollen in a 4,000-year core from a lake bed indicate declining vegetation (and rainfall) for several centuries after A.D. 100 —when the Roman Warming gave way to the Dark Ages.59 After 900, increased pollen indicated greater numbers of plants and warmer temperatures, followed by the Little Ice Age and another pollen decline.
