Received: 10 Sep 2013 – Revised: 23 Oct 2013 – Accepted: 24 Oct 2013 – Published: 01 Nov 2013 Abstract. Solar activity changes with time in a cyclic pattern. The
origin of those changes may be caused by planetary motion around the Sun,
affecting the position of the Sun's motion with respect to the centre of
mass and subjecting the Sun to changes in angular momentum and gravitational
tidal forces. With modern achievements, this multi-body problem can now be
addressed in a constructive way. Indeed, there are multiple criteria
suggesting that the solar variability is driven by a planetary beat also
affecting a number of terrestrial variables: 14C and 10Be
production, Earth's rotation, ocean circulation, paleoclimate, geomagnetism,
etc. The centennial changes between grand solar maxima and minima imply that
we will soon be in a new solar minimum and, in analogy with past events,
probably also in Little Ice Age climatic conditions.
