Galaxy Project IV: Galactic Climate Change

Part 4 of the Basement’s Galaxy Class Series. To understand the climate we experience on Earth we have to know our Galactic environment. As the Solar System travels through the Galaxy–into and out of its spiral arms, above and below the disk, through regions of higher and lower amounts of activity–the Earth’s climate system has changed and evolved in response. Our Earth’s own history provides a new window into the study of our Galaxy.
