This of the 100 kyr Glacial Cycle:
eccentricity or orbital inclination?[/url] paper claims to solve 4 of the 6 problems with Milankovitch cycles Wikipedia Milankovitch cycles. I was very impressed, but presumably their suggested mechanism for climate change, namely extraterrestrial accretion of dust or meteoroids, has not been supported by recent findings. Is it not worth considering another possible mechanism, when the inclination cycle solves so much?

- 100,000-year problem
- 400,000-year problem (Stage 11 problem)
- Causality problem (Stage 5 problem)
- The unsplit peak problem
The existence of the 100 kyr cycle of orbital inclination does not seem to have been previously noticed by climatologists. It may have been missed for two reasons. Ever since Milankovitch, the implicit assumption has been that insolation is the driving force for climate cycles, and insolation is not directly affected by orbital inclination. In addition, the 100 kyr cycle is not evident until one transforms to the invariable plane, or to a plane close to it.
