Argument: The sun is the primary driver of global climate change

]Principal argument: changes in global temperature correlate best with solar variations
Sun spots are intense magnetic fields that appear at times of greater solar activity. They often "explode" in an event known as "solar flares", which release a massive amount of electromagnetic radiation. This radiation reaches the earth and interacts with its atmosphere...
- Present graphs of correlation of temperature and C02 over 20th century and temperature and sun variations (from "the Great Global Warming Swindle).
]Correlation between sunspots and sea surface temperature
The graph at right demonstrates a very strong correlation between sun spots and sea surface temperature.
]1991 Danish Meteorological Institute
Found strong correlation between sun spots and global temperature in history. 400 years worth. Graphical coverage of this in part of a YouTube vidoe of the "Great Global Warming Swindle" [1]
]Sevenemark and Christiansen study
]Ian Clark study
]1859 Sun storm incident
Reportedly, the sun increased in brightness by a factor of two, with a presumably higher temperature effect in the atmosphere at that time as a result.

Book written in 2007 by Danish scientist Henrik Svensmark and British science writer Nigel Calder.
