What Really Drives Climate Denial?

I don’t know that anybody knows the answer for certain. But I’m almost certain that it doesn’t have much to do with the data. (More on that below.) In this morning’s Times, an economist (admittedly, a liberal one), offered as good an answer as any I’ve heard yet:

“Think about global warming from the point of view of someone who grew up taking Ayn Rand seriously, believing that the untrammeled pursuit of self-interest is always good and that government is always the problem, never the solution. Along come some scientists declaring that unrestricted pursuit of self-interest will destroy the world, and that government intervention is the only answer. It doesn’t matter how market-friendly you make the proposed intervention; this is a direct challenge to the libertarian worldview.”

In short, it’s not about facts; it’s about defending a worldview.

Today, I got a comment on Beloved Planet that almost certainly bolsters this argument. The comment’s writer makes a remarkable claim: That there’s been no global warming for 17.8 years. This is offered as a fact. The “fact” is accompanied by an effort – easily debunked – to discredit other sources I had cited as “staunchly left wing” – a harbinger of the ideology that surely drives this person’s view of climate change.

But what about the “fact?” Is it possibly true? Does the proponent of the fact believe it himself, or is it just another effort to manufacture doubt? Well, you take a look, and make up your own mind. Here’s the global temperature data, as assembled by the four global meteorological organizations that do this sort of thing, including the USA’s NASA and NOAA:

So what do you think? Can we argue – by selecting a runaway record hot year, 1998, as a starting point – that the global climate isn’t warming? Continue reading
