"find that the maximum variations of [the Sun's specific potential energy storage] correspond remarkably well with the occurrences of well-documented Grand Minima (GM) solar events throughout the available proxy solar magnetic activity records for the past 1000 yr."The paper finds "Grand Minima are related to the Sun's closest approaches to the barycenter," and predicts another Grand Minimum in solar activity will occur around 2150 AD. Several other researchers have linked changes in solar activity to the Sun's orbital position relative to the barycenter of the solar system, which along with multiple solar amplification mechanisms may possibly one day lead to a "unified grand theory of Earth's climate."

|Sun's potential energy [PE] is related to its position relative to the barycenter of the solar system, as shown in 2nd graph, and corresponds "remarkably well" with the minima of reconstructed sunspot numbers [SN] shown in bottom graph|
