The solar magnetic activity and earth's climate

Abstract
In this article I am going to describe the new picture of the Sun and how that can help us understand the influence of the solar activity on earth's climate. Helioseismology has started to reveal the causes of the solar activity, i.e. how the solar dynamo operates. In this article I will use the North Atlantic Oscillation as an indicator of the climate to illustrate how the solar activity can influence the climate. Finally, I describe the solar activity the last 1000 years and next coming 100 years.
