Global Warming and Climate Change – Cosmic Rays vs. Humans

In an earlier post I noted how there are peer-reviewed scientific studies that suggest solar activity is related to Global Warming. Now there are studies that suggest high energy cosmic rays can influence the climate. In Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences the “Experimental evidence for the role of ions in particle nucleation under atmospheric conditions” describes how levels of cosmic rays dramatically affect cloud formation. Since lower cosmic ray level result in less sun-shielding clouds; hence more heat.

The bottom line is that this kind of valid scientific analysis suggest the climate change picture is far more complex that human-caused “greenhouse gases.” The unfortunate reality is these studies are not being discussed by either the media or the political dialog in Washington or Europe. As a result, with Global Warming, people are being sold an ideologically driven belief sanctioned by the government. As the evidence mounts, it is clear that “Big Science” has lost all sense of objectivity in favor of the funding carrot of the politically motivated eco-religion.

A missing link in climate theory

The experimental results lend strong empirical support to the theory proposed a decade ago by Henrik Svensmark and Eigil Friis-Christensen that cosmic rays influence Earth’s climate through their effect on cloud formation. The original theory rested on data showing a strong correlation between variation in the intensity of cosmic radiation penetrating the atmosphere and the amount of low-altitude clouds. Cloud cover increases when the intensity of cosmic rays grows and decreases when the intensity declines.

It is known that low-altitude clouds have an overall cooling effect on the Earth’s surface. Hence, variations in cloud cover caused by cosmic rays can change the surface temperature. The existence of such a cosmic connection to Earth’s climate might thus help to explain past and present variations in Earth’s climate.

Interestingly, during the 20th Century, the Sun’s magnetic field which shields Earth from cosmic rays more than doubled, thereby reducing the average influx of cosmic rays. The resulting reduction in cloudiness, especially of low-altitude clouds, may be a significant factor in the global warming Earth has undergone during the last century. However, until now, there has been no experimental evidence of how the causal mechanism linking cosmic rays and cloud formation may work.

‘Many climate scientists have considered the linkages from cosmic rays to clouds to climate as unproven,’ comments Eigil Friis-Christensen, who is now Director of the Danish National Space Center. ‘Some said there was no conceivable way in which cosmic rays could influence cloud cover. The SKY experiment now shows how they do so, and should help to put the cosmic-ray connection firmly onto the agenda of international climate research.’
