Sloan and Wolfendale (2013) demonstrated that while temperature models showed a small correlation every 22 years, less than 14 percent of global warming since the 1950s could be attributed to cosmic ray rate.
A research by Sloan and Wolfendale (2013) showed that although temperature models indicated a recurring pattern every 22 years, only about 14% of the observed global warming since the 1950s can be attributed to fluctuations in cosmic ray intensity.
