It’s not until you get past Pamela and Viking that you get to the magnetic variation as a likely cause. Then there is always solar inertial motion.

Over at Climate Dialogue we have started a new discussion about the influence of the sun on the climate. People familiar with climate discussions know that the sun has been and still is a popular argument to explain at least part of the warming since 1750. This has to do with solar proxies correlating well with climate proxies (in the distant past), although Willis Eschenbach in a series of posts here at WUWT has shown that the solar signal is often not easily detected in climate records.
Also the Little Ice Age coincided with the Maunder Minimum, a period with few visible sunspots. So if the sun played a role in the past, why shouldn’t it in the present?
But figuring out how the sun has varied in e.g. the past millennium isn’t easy. And in fact, the science seems to be developing in…
