Solar Activity and Svalbard Temperatures

Technical Rating: star star
This paper compares the long temperature record at Svalbard, Norway to solar activity. The length of the solar cycle is strongly negatively correlated with the Svalbard temperatures with a time lag of 10 to 12 years. The data "show that 60% of the annual and winter temperature variations are explained by solar activity." The authors predict the Svalbard temperatures to decrease from 2009 to 2020 by 3.5 C.



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.
