However, in the interests of bonhomie:
You can also argue that there is a correlation between solar energy and global warming, which is the explanation for all previous global warmings.

Where does this say anthing about climate change? It specifically talks about global warming. Is there a method of warming up the earth that doesn't involve the sun?

You still said it.

Let's assume it isn't a misquote, I'll defend it anyway because there is nothing in it that I particularly disagree with. You haven't answered the question.

Any others?

No-one's arguing about heat sources!

The whole debate centres on what *happens* with the heat that is there, whether it comes from the sun (the vast majority) or any other source.

Limburg, in one translation of an interview from the German, seems to imply that the greenhouse effect doesn't exist at all. Now, if that's what he really means, he is totally wrong. If he's being misquoted or misinterpreted he's no different from what has happened with Jones et al - ie., words taken out of context.

"And yet changes in solar irradiation have caused most, if not all, previous climate changes."

What I was trying to do was achieve fair and open discussion on the subject, by moving back to basics and finding a point of common agreement, then moving forward from there.

At the moment we leap around (myself included) suddenly throwing new issues into the mix.

Well, as far as I can tell LF is, but since (s)he never actually says anything it's a bit hard to tell.

If we assume that all previous warming of the planet was natural, there needs to be a strong argument that the current warming is not natural before we look for another cause. Is it not reasonable therefore to put the burden of proof on those who claim that it is unnatural?

It's a shame that you have to resort to insults. I answered your question. You just didn't like the answer.

Whether I wrote this or not, you appear to be incapable of seeing the conditional clause: "most, if not all"

Anyway, I know what my theory is. What's yours?

In respect of this, can we all agree that none of the previous climate changes on planet earth were caused by humans?

So you agree that current climate change is caused by humans?

You're very keen on telling me what I think. Or at least what you want me to think. Are you a priest?

I was asking a question.

No I am not a priest, it is you that seems to like to comment about religion. I do agree none of the previous climate change (e.g. before the Pleistocene) on planet earth were caused by humans.

ooh, i can't help myself . . .

as along as we all agree that the current warming is caused by humans!

Everything before 2.5 million years ago. Did humans cause climate changes during the pleistocene? This seems unlikely to me since humans didn't evolve until the very end of it. But I suppose it's a start.

So we agree that climate changes can be entirely natural?
