There's no way it would be caused by sun cycles:

Thanks for the chart. It shows a good, not perfect, overlay of the solar cycle and Northern Hemispheric land temperature over three centuries. Someone has the numbers to calculate the correlation. Looking at the graph, we know the computed correlation will be high. If the underlying data is at least tolerably good, then this is significant. I know earth temperature does not cause solar cycles. So causation would be from solar activity to earth temperature. It would be nice if we could extend the chart back through time.

I think this chart is persuasive. What, if anything, is wrong with it?
