Effect of insolation variations on vegetations of the Eurasian subarctic during the Holocene
Abstract Variation of the insolation is one of the global factors which determine the Earth’s climate. Multi-periodic variations of the insolation determine the cyclicity of the Earth’s climate. The aim of the investigation is the estimation of the insolation variations influence on vegetations of t...
