for global warming, a Boulder researcher reports.

Some had estimated that the sun, by spitting out more radiation, was responsible for as much as 30 percent of the last century's warming, said Tom Wigley, a climate researcher with the National Center for Atmospheric Research in Boulder. He calculates that the figure is closer to 5 percent, "probably too little for a practical influence on climate."
Sallie Baliunas, a researcher with the Harvard-Smithsonian Center for Astrophysics, agreed with Wigley that the sun's total energy output hasn't changed much during the last century.
