Just close your eyes and click your heals together and just keep repeating "there's no place like home, there's no place like home". Should do the trick!
When I completed my degree in Geophysics, lecturers reviewed two theories. One was that ice ages were due to lots of precipitation, because somehow the Arctic Ocean was open and the continental masses were frozen.
The other theory was that ice age expansions and interglacials were caused by changes in the amount of energy hitting the Earth.
And this varied due to orbital mechanics.
All that was needed for an interglacial was that each melt season lost more snow and ice than was deposited.
Made sense to me then, but there was not enough evidence to confirm either theory.
Then, in the late 1960s, data started to accumulate and it confirms the orbital mechanics that temp of the climate varies due to changes in the amount of heat received at the Earth's surface.
For me, it has been a fascinating interest for a long time.
If you turn your attention from glib comments to a serious review of the literature, you might find it as rewarding as I have.
Worth the try.
