Abstract
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.
Keywords: ice age, mass extinction, galaxy, cycle
