In another video Clif explains the GSM. Basically, cosmic rays bombard through space, and have areas of thick and thin based on where the solar system is on the galactic plane.
The cosmic rays impact the core of the sun and contribute to it's internal heat and overall size. Supposedly, we are in a low density medium of cosmic rays and the sun has shrinked in overall size, which means an imperceptible lower amount of solar light (in all spectrum) falling upon the planet. With less overall light warming the planet, it cools over time until the cycle reverses.
I might have it not quite right but that was the gist I came away with.
