As if that's not enough, the sun appears to be dropping into another "grand minimum" which greatly reduces the sun's magnetic field. This reduces the earth's shielding from cosmic rays. So over the next ~50 years we'll see more cosmic rays and thus more clouds. And colder temperatures.


This fits in with Steiner's galactic model for glaciation:

gsabulletin.gsapubs.org

A partly speculative galactic model has been derived from present general knowledge of the Milky Way galaxy. This simple model is shown to be approximately 80 percent valid in terms of Newtonian gravitational theory. A model applying Newtonian gravitation more strictly would be more complex. According to the model, the solar system experiences a periodically and episodically varying galactic parameter during its orbits as far back as 3,000 m.y. Minima of the varying galactic parameter correlate with Phanerozoic and Precambrian glaciations well. The reason for these apparent correlations is not known, but they suggest the possibility of a causal relation.



Steiner couldn't explain the mechanism, but CERN's recent empirical validation of the theory that cosmic rays create nucleation and therefore clouds, fits with Steiner's observation in that when the earth is closer to the galactic center, it receives more cosmic radiation resulting in more and denser cloud cover, in turn leading to glaciation.
