CERN Finds "Significant" Cosmic Ray Cloud Effect

Technical Rating: star
Results of the CLOUD experiment at CERN in Geneva show big effects of pions from an accelerator, which simulate the cosmic rays and ionize the air in the experimental chamber. The experiments show that cosmic rays strongly enhance the formation rate of aerosols by up to ten fold. The aerosols may grow into cloud condensation nuclei on which cloud droplets form. The results show that variations in the sun's magnetic field, which changes the cosmic ray flux likely has a significant effect on clouds and climate.

Cosmic Rays Linked to Aerosols and Cloud Formation

Technical Rating: star
Danish scientists reported in May 2011 that they have succeeded for the first time in directly observing that the electrically charged particles coming from space and hitting the atmosphere at high speed contribute to creating the aerosols that are the prerequisites for cloud formation. The study confirms correlations that show that the Sun in the primary climate driver.

Evidence for a Celestial Origin of Climate Oscillations

Technical Rating: star star star
Nicola Scafetta of Duke University compares the temperature record to planet orbital cycles. He finds that large climate oscillations with periods of 20 and 60 years are synchronized to the orbital periods of Jupiter and Saturn. A phenomenological model based on these astronomical cycles is used to well reconstruct the temperature oscillations since 1850. It is found that at least 60% of the global warming observed since 1970 has been induced by these natural climate oscillations. The gravitational tug of Jupiter and Saturn causes the sun to change speed as it orbits around the solar system centre of mass. These forces may affect the solar sunspot cycle, the solar flux and our climate.

Cosmic Rays and Climate

Technical Rating: star star
This paper from CERN presents evidence that cloud cover and climate are affected by cosmic rays, which are modulated by the solar wind and the galactic environment. It reviews the progress on understanding how cosmic rays affect the amount of low clouds.

Using the Oceans to Quantify Solar Forcing

Technical Rating: star star
A paper by Nir Shaviv shows that the solar forcing associated with the eleven year solar cycle is about seven times larger than that caused by the total solar irradiance variations. This article provides a summary of the analysis with a link to the technical paper.
