[Stilgar]

NASA and NCAR researchers show the Sun plays a big factor in climate change.

Shindell will discuss how he used a climate model that included solar radiation changes, volcanic eruptions, and natural internal variability to arrive at a more accurate look at Earth's changing climate today. Shindell said that while solar radiation changes and volcanoes exert a similar influence on global or hemispheric average-temperature changes, the solar component has the biggest regional effect over time scales of decades to centuries, while volcanoes cause the largest year-to-year changes.
