Whither Sol?

How might the Sun change on timescales of 100-1000 years? The answer is necessary to
assess the potential role of solar variability in climate change. We can look to the past
through proxy reconstructions of solar irradiance. Here we look inward, to our ability to
detect changes in the internal structure of the Sun; outward, to new resources for identifying
and studying "true" solar twins; and within, to advances in the modeling of short-term stellar
evolution and convective dynamos.
