“Actually, cosmic rays originate outside our solar system.”
Okay. I’d love to see the percentage breakdown between solar rays and cosmic rays that strike earth. I’m willing to bet that the vast majority of rays which hit Earth originate from our sun.

Umm, cosmic rays and solar rays are not the same thing. Cosmic rays are high energy radiation and energy spewed out by things like pulsars, supernova, black holes and all the stars with various events from the 300,000,000,000 stars in our galaxy and galactic core and also the few hundred billion other galaxies (that we can see). Its not just sunlight. For example, you have a few billion neutrinos from the other side of the galaxy zipping right through your body as if it wasn’t there, every second of every day. Our earths magnetic field protects us from our suns charged particles. But it takes the suns magnetic field to deflect these super energetic interstellar particles
The sun is not active right now. Few sunspots correlates to a weaker magnetosphere which allows a higher number of cosmic rays into the Earth’s SOI. When there are high number of sunspots, the Earth’s magnetosphere lights up (northern lights) and deflects away the worst of those solar rays.
Cosmic rays still make it through, but the heliosphere, the sun’s magnetosphere, extends way out past the orbits of the gas giants. When the sun isn’t active, that solar sheath is weaker, and more cosmic rays make it to the inner planets.
Couple a weak solar cycle with the solar system’s traversal through higher-cosmic-ray containing open space means we get bombarded and cloud cover increases. This causes cooling.
The nutjobs back in the 70s claiming we’re headed toward another ice age were more scientifically accurate than the global warming psychos we hear from now.
