You don't always need a complex testable model, especially one that sits only inside a computer. Sometimes all you need is the data (such as the graph I posted) and a brain.

I have seen no definite "causal links" other than theoretical ones. We have two pieces of strong data: CO2 is increasing, and so is temperature. Some of the CO2 is certainly man-made, particularly in recent readings, but CO2 and temperature have both been rising since the Little Ice Age.

It is already established that both tend to track each other and have done so as far back as we have data, long before humans were a factor. This is not the same as a causal link, either way. If you have strong data showing a distinct time gap outside the margins of error, one way or the other, show it to me.

Can you answer either of the following questions:

--What would initiate a CO2 spike along regular intervals over the last 500,000 years?

--If CO2 is causing the warming then what turns it off at the peaks? Every time? What can sharply reverse a runaway greenhouse effect?

A hypothesis, to be a good one, has to deal with all the parameters.

Vulcanism is a red herring. While volcanos have resulted in short-term changes, I don't subscribe to the theory that all the historical changes are due to volcanic activity. There is no more reason vulcanism should be cyclic than any other CO2 emissions should be.

As far as motivations are concerned, every last solution proposed for climate problems involves giving a centralized authority vast new controls over individual choice and the means of production. Every one. And usually by many of the same people who used to push socialism for other reasons. I go by their output. You can speculate all you want on their reasons for it.

Lovelock is an exception that proves the rule. Pro-nuclear "greens" are still few and far between, although I am seeing some hopeful signs from the more reasonable ones. This article opened my eyes on motives a long time ago. Not that much has changed.
