3) What can we learn of climate responses to solar variability using paleo climate records?
4) Are there any significant climate impacts of solar variability on regional scales?
5) What are the research directions, additional observations and/or model improvements necessary to improve our understanding and forecast ability regarding solar variability and climate, particularly over the solar cycle time scale?
