Based on mathematical analysis of Earth's glacial history and the record of mass extinctions over the Phanerozoic Era, past and recent theories have explored possible connections between geological history and the solar system's motion in the galaxy. Building on new evidence for these claims, this paper proposes a new mechanism for galactic influences on terrestrial climate: the moderation of galactic cosmic ray flux by the expanding and contracting Oort cloud under the influence of the galactic tidal field. This paper describes a model for the sun's orbit in the galaxy that can be tested against astronomical observations of the galaxy and paleoclimate studies from around the world.
