    "abstract": "Variations in the flux of Galactic Cosmic Rays (GCR) at Earth during the last\n4.6 billion years are constructed from information about the Star Formation\nRate (SFR) in the Milky Way and the evolution of solar activity. The variations\nof GCR show a remarkable resemblance to changes in Earth\u0027s climate during the\nperiod considered, suggesting that Earths climate is closely linked to the\nevolution of our Milky Way. The link could be significant in the solution of\nthe \u0027faint sun climate paradox\u0027.",
