COSMOCLIMATOLOGY A NEW THEORY EMERGES PDF

Search Menu Data on cloud cover from satellites, compared with counts of galactic cosmic rays from a ground station, suggested that an increase in cosmic rays makes the world cloudier. This empirical finding introduced a novel connection between astronomical and terrestrial events, making weather on Earth subject to the cosmic-ray accelerators of supernova remnants in the Milky Way. Herschel , Eddy , Friis-Christensen and Lassen , with the small 0. Clouds exert on average a strong cooling effect, and cosmic-ray counts vary with the strength of the solar magnetic field, which repels much of the influx of relativistic particles from the galaxy. The connection offers a mechanism for solar-driven climate change much more powerful than changes in solar irradiance. During the past 10 years, considerations of the galactic and solar influence on climate have progressed so far, and have found such widespread applications, that one can begin to speak of a new paradigm of climate change.

He previously headed the sun-climate group at DSRI. This theory had earlier been reviewed by Dickinson. Cosmoclimatology theory of climate change[ edit ] Svensmark detailed his theory of cosmoclimatology in a paper published in Fewer cosmic rays meant fewer clouds—and a warmer world.

In April , Svensmark published an expansion of his theory in the Monthly Notices of the Royal Astronomical Society [16] In the new work he claims that the diversity of life on Earth over the last million years might be explained by tectonics affecting the sea-level together with variations in the local supernova rate, and virtually nothing else. This suggests that the progress of evolution is affected by climate variation depending on the Galactic Cosmic Ray flux.

The connection to evolution is a culmination of this work. The hypothesis, verified by the experiment, is that electrons released in the air by the passing muons promote the formation of molecular clusters that are building blocks for cloud condensation nuclei.

CERN started a multi-phase project in , including rerunning the Danish experiment. CERN plans to use an accelerator rather than rely on natural cosmic rays. They show that vapor traces, assumed until now to account for aerosol formation in the lower atmosphere can explain only a tiny fraction of the observed atmospheric aerosol production. The results also show that ionization from cosmic rays significantly enhances aerosol formation.

They have studied in detail the physico-chemical mechanisms and the kinetics of aerosols formation. Galactic Cosmic Rays vs Cloud Cover[ edit ] In April , Professor Terry Sloan of Lancaster University published a paper in the journal Environmental Research Letters titled "Testing the proposed causal link between cosmic rays and cloud cover", [29] which found no significant link between cloud cover and cosmic ray intensity in the last 20 years.

Svensmark responded by saying "Terry Sloan has simply failed to understand how cosmic rays work on clouds". Giles Harrison of Reading University , describes the work as important "as it provides an upper limit on the cosmic ray-cloud effect in global satellite cloud data".

Harrison studied the effect of cosmic rays in the UK. Brian H. They also found that galactic cosmic rays, and total solar irradiance did not have any statistically significant influence on changes in cloud cover. Lockwood [34] conducted a thorough review of the scientific literature on the "solar influence" on climate. It was found that when this influence is included appropriately into climate models causal climate change claims such as those made by Svensmark are shown to have been exaggerated.

Sloan and Wolfendale [35] demonstrated that while temperature models showed a small correlation every 22 years, less than 14 percent of global warming since the s could be attributed to cosmic ray rate.

The study concluded that the cosmic ray rate did not match the changes in temperature, indicating that it was not a causal relationship. Extrapolating from the laboratory to the actual atmosphere, the authors asserted that solar activity is responsible for ca.
