Is global cooling in our future?

If you really want to annoy a climate alarmist cultist, you can assert that global cooling is what we should expect. Nobody knows what triggers little ice ages (LIAs), but some experts expect that a LIA may be coming our way. Why? They cite a strong correlation with a quiet Sun and prolonged absence of sunspots. Since I myself am an instinctive contrarian. I find the hypothesis attractive. If you want to investigate the idea for yourself, take a look at the work of Willie Soon (Harvard Smithsonian Center for Astrophysics), Russian Astronomer Habibullo Abussamatov, and Harjit Ahluwalia (University of New Mexico).

Also worth your attention is the work of Henrik Svensmark, a physicist in the Astrophysics and Atmospheric Physics Division of the National Space Institute in Denmark. As noted by Tom Harris and Jay Lehr, “When the Sun is highly active, it has a stronger magnetic field;

  • this field blocks a significant fraction of the Galactic Cosmic Rays (GCR) entering our solar system from deep space;
  • since GCRs are understood to encourage cloud nucleation, the reduction in GCR entering the Earth’s atmosphere leads to less cloud formation on our planet;
  • since clouds are known to, generally speaking, cool the planet, less clouds means a warmer Earth.

The reverse is also believed to be the case: a weaker Sun produces a weaker magnetic field and so more GCRs are allowed to enter our atmosphere resulting in more clouds and hence a magnification of the slight cooling effect of a low TSI Sun.”
