Study: finds a solar amplification mechanism by which solar activity & cosmic rays control climate

Watts Up With That?

The HockeySchtick writes: A paper published today in the Journal of Atmospheric and Solar-Terrestrial Physics finds another potential solar amplification mechanism mediated by galactic cosmic rays [GCRs] (and distinct from Svensmark’s cosmic ray theory of climate). The author demonstrates:

  • Solar modulation of GCR [Galactic Cosmic Rays] is translated down to the Earth climate.
  • The mediator of solar influence are energetic particles.
  • GCR impacts the O3 [ozone] budget in the lower stratosphere.
  • O3 influences the temperature and humidity near tropopause, and greenhouse effect.
  • Effectiveness of this mechanism depends on geomagnetic field intensity.

“In this paper we show that bi-decadal variability of solar magnetic field, modulating the intensity of galactic cosmic ray (GCR) at the outer boundary of heliosphere, could be easily tracked down to the Earth’s surface. The mediator of this influence is the lower stratospheric ozone, while the mechanism of signal translation consists of: (i) GCR impact on the lower stratospheric…
