Contribution of Cosmic Ray Flux to Global Warming

Technical Rating: star
This paper by Dr. U.R. Rao shows that galactic cosmic rays, using 10Be measurements in deep polar ice as the proxy, has decreased by 9% during the last 150 years. The decrease in cosmic rays cause a 2.0% decrease in low cloud cover resulting in a radiative forcing of 1.1 W/m2, which is about 60% of that due to the CO2 increase during the same period.



Old Farmer's Almanac Predictions

Dr. Tim Ball discusses the predictions of the Old Farmer's Almanac Predictions of global cooling for the next several years.



Forbush Decreases - Clouds Relation in the Neutron Monitor Era

Technical Rating: star
Sudden decreases in cosmic rays called Forbush Decreases are used to test the theory that cosmic rays affect cloud formation. The diurnal (day to night) temperature range is used as an indicator of cloud cover. The study shows that large Forbush Decreases of ampltude more that 10% causes a 0.5 Celsius change in the diurnal range, confirming that cosmic rays affect cloud cover.



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.
