Solar Activity During the Last Millennium
First Aired: 05/12/2010
The sun dominates life on our planet, yet we know astonishingly little about long-term variation in solar activity and how it might have influenced Earth’s climate. Join Devendra Lal as he explains how chemical clues locked in Antarctic ice can reconstruct 1,000 years of solar activity and how this knowledge is critical to understanding Earth’s climate history.
