The sun’s output varies in several ways on many time scales (including the 11-, 22 and 80-year solar cycles), with concomitant effects on Earth’s climate. While changes in visible radiation are small, changes in particle flux and magnetic field are known to exercise a strong climatic effect. More than 50% of the 0.8ºC rise in AGT observed during the 20th century can be attributed to solar change.
|Cumulative solar irradiance (blue) and volcanic forcing (red) is
highly correlated with HadCRU global temperature and explains
the trend in temperature since 1950.
The direct solar irradiance (orange) is uncorrelated with temperature.

According to authors Dr. Sebastian Lüning and Prof. Fritz Vahrenholt, the book is up-to-date, cites hundreds of peer-reviewed literature and explains in easy terms why the CO2 climate sensitivity has been totally overblown and how the sun and oceans are the primary climate drivers.
