text: Evidence Shaky for Sun's Major Role in Past Climate Changes National Center for Atmospheric Research -- Computer models of Earth's climate have consistently linked long-term, high-magnitude variations in solar output to past climate changes.     Now a closer look at earlier studies of the Sun casts doubt on evidence of such cycles of brightness, their intensity and their possible influence on Earth's climate...
