In the judgment of the two researchers, the role of solar activity in causing climate change “remains unproven.” However, as they state in the concluding sentence of their abstract, “the weight of evidence suggests that solar changes have contributed to small climate oscillations occurring on time scales of a few centuries, similar in type to the fluctuations classically described for the last millennium: the so-called Medieval Warm Period (900-1400 A.D.) followed on by the Little Ice Age (1500-1800 A.D.).”
