It's tough to discern the subtle climatic effects of solar variation amidst a cacophony of strong earthly influences--greenhouse gases, volcanoes, sulfate aerosols, to name a few. But only in the past decade or so have these and other kinds of solar variations begun to be tied to climate shifts on Earth - first tenuously, and more solidly of late.
