What we cannot say is what Cycle 26 will look like—mainly because no one has a demonstrated method for predicting that far ahead. http://solarsystemcentral.com/sunspot_cycles_page.html Webthe residual values show distinct cycles with periods of about 2,000 years (Hallstadtzeit Cycle; fig. 2B). A closer look at the tree-ring ∆14C reconstruction for the last 1,000 years shows that 14C was higher during the Maunder and Spörer Minima, but also shows that there were peaks in 14C production centered on about A.D. 1300 ecology and evolution 小木虫
