Following evidence last year from Mike Lockwood at the Rutherford Appleton Laboratory in the UK that there was no link between the sun’s magnetic activity and global temperatures, the “sun activity” theory received a further blow from research findings by a team from the University of Lancaster.

The U Lancaster team found “no significant link between cosmic rays and cloudiness in the last 20 years,” leading them to endorse the IPCC, who last year stated that since the 1970s, the “contribution of humankind’s greenhouse gas emissions has outweighed that of solar variability by a factor of about 13 to one.”
