I am still trying to understand Global Warming -- and the topic just
seems not to go away -- even Gore on Oprah for Pete's sake.
Do I understand correctly? -- sort of?:
Every 23kyr or so the Earth warms up -- and some 12kyr later it
freezes.
Ocean level varies some 30m in the process.
The people in Florida don't much like this; the people in Canada
are delighted when
it gets warmer.
... But why 23kyrs? Well that is the period of the Earth's
precession.
But why does the precession change the Earth's average
temperature? Yes, the tilt tinkers with weather patterns, but the
cross section toward the Sun doesn't change.
A bit of tutoring would be appreciated.
