Abstract

Variations in the flux of Galactic Cosmic Rays (GCR) at Earth during the last 4.6 billion years are constructed from information about the Star Formation Rate (SFR) in the Milky Way and the evolution of solar activity. The variations of GCR show a remarkable resemblance to changes in Earth's climate during the period considered, suggesting that Earths climate is closely linked to the evolution of our Milky Way. The link could be significant in the solution of the 'faint sun climate paradox'.
