The CERN report does not say anything about the sun and global warming. You want to know how I know? Because the scientist who led the project says so.

Here, I’ll like to the ‘basic’ explanation on skeptical science so that you can understand.

skepticalscience.com

“At the moment, it actually says nothing about a possible cosmic-ray effect on clouds and climate, but it’s a very important first step”

Further explanation of what the experiment was, and what it didn’t prove— what in fact we know not to be true.

In reality, the CERN experiment only tests the bolded step in this list of requirements for cosmic rays to be causing global warming:

Solar magnetic field must be getting stronger
The number of cosmic rays reaching Earth must be dropping
Cosmic rays must successfully seed clouds, which requires:
Cosmic rays must trigger aerosol (liquid droplet) formation
These newly-formed aerosols must grow sufficiently through condensation to form cloud-condensation nuclei (CCN)
The CCN must lead to increased cloud formation
Cloud cover on Earth must be declining

In short, the CERN experiment only tested one-third of one out of four requirements to blame global warming on cosmic rays. Additionally scientists have measured solar activity and the number of cosmic rays reaching Earth, and neither meets the first two requirements listed above. Both solar magentic field strength and the number of cosmic rays reaching Earth have been flat over the past 50+ years (Figure 1).

Do you deny that that last bolded sentence is true?
