This excellent exposition is worth reading if you can push past the interviewer’s sections to see what a world-renown scientist has to say about how we got to where we did in the whole climate change ‘thing’. Freeman Dyson’s ’s sage, seasoned and holistically wise views (taking in biology and human nature in addition to physics — his primary field) stand in stark contrast to the interviewer’s unfortunately blatant (but ironic ) antagonistic editorial agenda — something about which he seems either unaware or unconcerned.

My objections to the global warming propaganda are not so much over the technical facts, about which I do not know much, but it’s rather against the way those people behave and the kind of intolerance to criticism that a lot of them have…

I was involved in climate studies seriously about 30 years ago [and]… got a very strong feeling for how uncertain the whole business is, that the five reservoirs of carbon all are in close contact — the atmosphere, the upper level of the ocean, the land vegetation, the topsoil, and the fossil fuels. They are all about equal in size. They all interact with each other strongly. So you can’t understand any of them unless you understand all of them. Essentially that was the conclusion. It’s a problem of very complicated ecology, and to isolate the atmosphere and the ocean just as a hydrodynamics problem makes no sense…

…these models are very good tools for understanding climate, but they are not good tools for predicting climate… They are models, but they don’t pretend to be the real world. They are purely fluid dynamics. You can learn a lot from them, but you cannot learn what’s going to happen 10 years from now.

What’s wrong with the models… is that in the case of climate, very small structures, like clouds, dominate. And you cannot model them in any realistic way. They are far too small and too diverse. So they say, ‘We represent cloudiness by a parameter,’ but I call it a fudge factor. So then you have a formula, which tells you if you have so much cloudiness and so much humidity, and so much temperature, and so much pressure, what will be the result… But if you are using it for a different climate, when you have twice as much carbon dioxide, there is no guarantee that that’s right. There is no way to test it…

…enhanced carbon dioxide… has a drastic effect on plants because it is the main food source for the plants… So if you change the carbon dioxide drastically by a factor of two, the whole behavior of the plant is different. Anyway, that’s so typical of the things they ignore. They are totally missing the biological side, which is probably more than half of the real system…

…it’s a fact that they don’t know how to model it. And the question is, how does it happen that they end up believing their models? But I have seen that happen in many fields. You sit in front of a computer screen for 10 years and you start to think of your model as being real. It is also true that the whole livelihood of all these people depends on people being scared. Really, just psychologically, it would be very difficult for them to come out and say, “Don’t worry, there isn’t a problem.” It’s sort of natural, since their whole life depends on it being a problem. I don’t say that they’re dishonest. But I think it’s just a normal human reaction. It’s true of the military also. They always magnify the threat. Not because they are dishonest; they really believe that there is a threat and it is their job to take care of it. I think it’s the same as the climate community, that they do in a way have a tremendous vested interest in the problem being taken more seriously than it is…

There’s a lot made out of the people who died in heat waves. And there is no doubt that we have heat waves and people die. What they don’t say is actually five times as many people die of cold in winters as die of heat in summer. And it is also true that more of the warming happens in winter than in summer. So, if anything, it [global warming] is heavily favorable as far as that goes. It certainly saves more lives in winter than it costs in summer.

So that kind of argument is never made. And I see a systematic bias in the way things are reported. Anything that looks bad is reported, and anything that looks good is not reported.

A lot of these things are not anything to do with human activities. Take the shrinking of glaciers, which certainly has been going on for 300 years and has been well documented. So it certainly wasn’t due to human activities, most of the time. There’s been a very strong warming, in fact, ever since the Little Ice Age, which was most intense in the 17th century. That certainly was not due to human activity.

And the most serious of almost all the problems is the rising sea level. But there again, we have no evidence that this is due to climate change. A good deal of evidence says it’s not. I mean, we know that that’s been going on for 12,000 years, and there’s very doubtful arguments as to what’s been happening in the last 50 years and (whether) human activities have been important. It’s not clear whether it’s been accelerating or not. But certainly, most of it is not due to human activities.

…if they find any real evidence that global warming is doing harm, I would be impressed. That’s the crucial point: I don’t see the evidence…

And why should you imagine that the climate of the 18th century — what they call the pre-industrial climate — is somehow the best possible?

There’s much more. Definitely worth the time.

UPDATE I: From the hallowed halls of Princeton University to the strip malls of Mississippi… one man’s bologna is another’s baloney.

UPDATE II: This from the WSJ is also relevant.

…the Annan report deserves even closer scrutiny as an example of the sleight of hand that so often goes with the politics of global warming. Unlike starvation, climate change does not usually kill anyone directly. Instead, the study’s authors assume a four-step chain of causation, beginning with increased emissions, moving to climate-change effects, thence to physical changes like melting glaciers and desertification, and finally arriving at human effects like malnutrition and “risk of instability and armed conflicts.” This is a heroic set of assumptions, even if you agree that emissions are causing adverse changes in climate…

Writing in the Prometheus science policy blog, Mr. Pielke calls the report a “methodological embarrassment” and a “poster child for how to lie with statistics” that “does a disservice” to those who take climate change issues seriously…

Our only question is, if the case for global warming is so open and shut, why the need for a report as disingenuous as Mr. Annan’s?
