To address the first comment:

No, "falsifiability" does not automatically invalidate a theory because of uncertainty. Also, from a policymaker's point of view, one doesn't need 100% certainty to formulate a rational policy.

Second, there are multiple lines of evidence supporting anthropogenic global warming (AGW). The data is messy, but the trends persist.

Third, you mention studies, but there are no citations? How on earth can one explore scientific ideas without concrete details?

Fourth , about cosmic rays, the scientists at skeptical science write,

Hypothetically, an increasing solar magnetic field could deflect galactic cosmic rays, which hypothetically seed low-level clouds, thus decreasing the Earth's reflectivity and causing global warming. However, it turns out that none of these hypotheticals are occurring in reality, and if cosmic rays were able to influence global temperatures, they would be having a cooling effect.
