BERYLLIUM-10 AS AN INDICATOR OF LONG-TIME QUASI-PERIODIC FLUCTUATIONS OF SOLAR ACTIVITY AND GROUND TEMPERATURE OF THE NORTHERN HEMISPHERE IN THE LAST MILLENNIUM
Abstract
The investigation reveals quasi-periodic fluctuations of 10Ве which can be considered the geophysical indicator of quasi-periodic fluctuations of the ground temperature with the period of 60 years and which are characteristic both for the previous thousand-year period and for the present. The obtained result also allows quite reasonably to include the 60-year-period fluctuations, which obviously have natural character and can cause in certain periods even greater amplification or, on the contrary, some levelling of the global warming effect, into the temperature changes scenarios in the 21 century.
