The changing solar energy output: Does it affect us?
Provided by: Laboratory for Atmospheric and Space Physics
Once thought to be constant, the Sun's energy output actually varies over time-scales of minutes and days and over decades and centuries. The most prominent variation is the 11-year solar cycle. Our current understanding of these variations is only possible through very detailed observations both from the ground and space. In this LASP public lecture from March 3, 2009, Dr. Margit Haberreiter discusses what we have learned about our closest star and what we have yet to discover, including whether variations of the Sun can have an affect of Earth's climate.
