Fiction: Global Warming is Caused by Cosmic Rays
The claim: Cosmic rays increase low level clouds. When the sun is strong, cosmic rays decrease which decreases clouds – causing a warmer climate.
Figure 1 (Laut, 2003) shows cosmic ray intensity vs. low cloud anomalies.
There is NO DEFINITIVE LINK between cosmic rays (red) and low clouds (blue). Quite the opposite is true: since 1991 there has been NO COORELATION.
Figure 2 Solanki & Krivova, 2003) shows cosmic ray intensity vs. global temperature anomaly. Cosmic ray intensity shows NO COORELATION TO CLIMATE since 1985.
Newer studies reveal that cosmic rays cannot explain the modern day global warming:
Erlykin, et al. (2009): "The analysis made in the present work, as well as arguments presented in our previous publication ( Sloan and Wolfendale, 2008 ), gives sufficient basis to argue that CR are not the dominant factor in the formation of clouds."
Erlykin, Sloan, & Wolfendale (2009): " We deduce that the maximum recent increase in the mean surface temperature of the Earth which can be ascribed to this activity is < 14% of the observed global warming."
Pierce & Le Page (2007): "Observations from satellites and model simulations do not support the cosmic ray hypothesis as a major role in low cloud coverage and climate change."
Peter Laut, Professor (emeritus) of physics at The Technical University of Denmark and former scientific advisor on climate change for The Danish Energy Agency has a very good history of the cosmic ray hypothesis, its failures, and its strange following which can be read here.
