There is reasonably good geophysical evidence for a correlation between such astronomical changes and the climate on Earth, particularly the ice ages. This is known as the "Milankovitch Effect."link
Thanks, another good point.
There are *so* many other variables that their models don't take into account, it's rather laughable to consider their models anywhere near complete.
Obviously, I havent got that memo yet. /s
The tilts that cause glacial ages occured in immensly long periods of time. so the warming cannot be attributed to the Milankovitch effect, of course, or to solar output. We are left with Greenhouse emmissions.
You are omitting hundreds if not thousands of other possibilities in your process of elimination.
