Solar activity over nine millennia: A consistent multi-proxy reconstruction

Posted: April 14, 2018 by tallbloke in Astronomy, Astrophysics, Solar physics, solar system dynamics

There’s a new paper coming out in Astronomy and Astrophysics from Wu, Usoskin et al that is of interest to us. It reconstructs solar activity over 9 millennia. When I get a copy of the data, I’ll compare it to Steinhilber et al’s 2012 effort.

    SOLAR ACTIVITY OVER LAST 9000 YEARS SHEDS NEW LIGHT ON NATURAL VARIABILITY

    A new consistent reconstruction of the solar activity offers a more reliable estimate of the long-term evolution of the solar variability

    If the suns poles did not reverse, there would be no sunspot activity, dips towards zero are points when the suns polar reversal slowed down. Going back in time toward the climatic optimum the suns poles reversed more regularly producing more activity. It’s what brought us out of the last major glacial period.
