A Democrat-voting, tofu-eating environmentalist has written movingly about his conversion to the light on climate change.

My name is David Siegel. I’m not a climate expert; I’m a writer. Early in 2015, I became interested in climate science and decided to spend the better part of this year trying to learn what I could. It didn’t take long before it was clear that there isn’t likely going to be any catastrophic warming this century.

Now Siegel – author of several bestselling business books – is trying to persuade his fellow liberals to follow his example by doing what he did, examining their prejudices and looking at the facts.

To this end, he has written a 9,000 word essay explaining where the alarmists have got it wrong. But he doesn’t hold out much hope: it was rejected by every one of the liberal publications in the US to which he submitted it, among them the LA Times, the Atlantic Monthly, National Geographic and Huffington Post.

Siegel begins with a ten short statements designed to challenge the usual liberal assumptions on climate change. Here they are:

Every one of the statements is evidence-based and supportable, of course, but like Siegel I hold out little hope that they stand any chance of penetrating the liberal-left mental firewall.

In my experience – and I’ve been fighting the climate wars for over a decade – this debate has always had far more to do with ideology than it does with the hard scientific facts, which on the whole are far less helpful to the liberal cause than they are to the conservative one.

Where I disagree with Siegel’s essay is where he says that “skeptics are losing this battle”. Sure, if we’re talking Gramsci-style about all the institutions the Warmists have captured – NASA, the New York Times, NOAA, the Royal Society, the NAS, the seats of academe, the UN, the EU, etc – then he definitely has a point.

But I think as far as the generality of the populace is concerned, climate change has ceased to be the red-button issue it was at the height of the 90s scare during the period where the world actually was still getting warmer.

It’s nice that David Siegel has seen the light (“likewise joy shall there be in heaven over one sinner that repenteth, more than over ninety and nine just persons”). It’s sweet that he’s trying to convert a few more of the liberal heathen. Really, though, does any of us actually care that most liberals are wrong on climate change? And if they did all convert wouldn’t it suddenly snatch away one of life’s great pleasures: tormenting liberals with inconvenient facts?
