Abstract
Bog deposits that have existed for many thousands of years are valuable sources of information about changes in the Earth’s climate in the past. One of the possible reasons for the change in the Earth’s climate is the variations in solar radiation coming to the Earth’s surface, due to the change in time of solar activity (SA). Thus, during the Little Ice Age (LIA), the well-known SA minima, the Spörer, Maunder, and Dalton minima, took place. This paper considers a possible relationship between changes in the growth rate of bog sediments and SA variations. In particular, it is shown that the decrease in the growth rate of bog deposits in the first millennium BC may be the result of a decrease in SA, which caused cooling on the Earth.
