I will take Ians advice and get a copy of Plimers book and then compare what he has to say. Regardless of the results you lot have had Al Gore for so many years its about time we had someone of his high esteem.

Just a comment on the CO2 and temp thing, you say and i quote for simplicity

“Changes in the Earth’s orbit around the Sun (known as Milankovitch cycles) slowly warm the planet. This warming triggers increases in CO2 and other greenhouse gases in the atmosphere, which cause further warming,” and so on.

You do realise that this warming you speak of is the temperature rising right? So what you are saying is that the temps start to rise and then CO2 then begins to rise in what you might say a delayed fashion?

Or to put it another way the CO2 lags the temps? To prove your point you need to demonstrate a situation where the CO2 rises independantly of the temp, this rise via IR absorption etc THEN causes the temps to increase.

What you have written simply confirms what the geological record shows.

Cheers
