I've added an NPOV tag to this article because the current version tries to hide the most important modern insight about the cycles, included in Roe's 2006 paper. I encourage educated readers to read the paper , check its merits and citations, decide whether I am right that it is impossible for the content of this paper to be neglected or denied by this Wikipedia article, and fix all the obsolete information on this page. Many things claimed to be problems of the theory have been resolved. WMC has very "unrelated" reasons why he wants the key paper by Roe to be suppressed - they're much more related to other theories about the climate than the content of this article which is the Milankovitch theory.
