The Sun, Climate, and a New Solar Mission

The Sun provides nearly all the energy for the Earth's climate system. Even small changes in the Sun's energy output can have large effects on climate, since the energy received from the Sun is so much greater than all other climate energy sources combined. Fortunately, the Sun is extremely stable, but this makes it very difficult to measure changes in its output over long periods of time—the types of measurements needed for climate records.

How variable is the Sun? And how much does it affect the Earth's climate compared to other natural effects or to human-caused influences? How do we measure it to the needed levels of accuracy?

In this LASP Public Lecture from May, 2013, Dr. Greg Kopp discusses what we know about the Sun and its influences on Earth's climate, and describes the current and planned measurements of this important solar climate data record.
