Mike,
Three Concepts:

The Milankovitch Glaciation Cycle
The Maunder Sunspot Cycle
The Historical Record of Climate Change Events

No dicussion of global climate change can possibly take place without an appreciation of these incontrovertible effects.

Those who are loud proponents of Global Warming very often have not even HEARD of these things.

Good list!

I would just like to highlight the slow movement of continents across the planets surface (implied in your third item).

The world has been in an ice age for 2.6 million years - the biggest driver behind this change was the Antarctican landmass moving to the pole.

That’s a huge area of land that is not only not receiving very much insolation ( = direct solar radiance, for the thread) but that also turned white (!). This has radically changed the earth’s heat budget.

It’s importance when talking about AGW is because it emphasizes the importance of insolation on land (rather than water). The time of the dinosaurs was on average 5 degrees C warmer than today - our earth got cold largely because of this single enormous change.
