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.

The Sun-Climate Connection

Technical Rating: star
This article reviews correlations between the Sun and climate, and discusses how the Sun can effect cloud formation by changing the cosmic ray flux.

Cosmic Ray Decreases Affect Atmospheric Aerosols And Clouds

Technical Rating: star
When solar explosions interfere with the cosmic rays there is a temporary shortage of small aerosols that seed the formation of liquid water droplets of low-level clouds. Because of the shortage, clouds over the ocean can lose as much as 7 per cent of their liquid water within seven or eight days of the cosmic-ray minimum.
