Episode Info

"The Sunspot Mystery" examines the way storms on the sun may affect the earth's weather. Noting that sunspots seem to follow 11-year cycles, the report traces scientists' efforts to link these to droughts in the Midwest. One theory examined states that a lack of sunspot activity from 1645 to 1715 caused the earth to cool considerably.
