«It's an astonishing result because this long cycle, which had been predicted from
planetary motions through about 50 million years ago, has been confirmed through at least 215 million years ago.
Fig. 9 summarizes a chain of mechanisms that, according to the finding of this paper, reasonably links the
planetary motion to climate change
through solar and heliosphere modulation of the magnetosphere and ionosphere that regulate the cloud cover percentage.
