Geomagnetic field-climate relationship studied

Is there a relationship between regional geomagnetic field changes and climate during the twentieth century? Many researchers have pursued this line of questioning since Paul Damon of the University of Arizona reported finding a relationship between radiocarbon in the atmosphere and the global geomagnetic field intensity.

He showed that as the geomagnetic field increased, the amount of carbon 14 in the atmosphere decreased. As somewhat of a side issue, Damon presented a curve showing how temperature has changed in the past 8000 years but concluded that the temperature change had only a minor effect on the carbon 14 concentration in the atmosphere.
