Al Gore likes to present himself as a tribune of science, warning the world of imminent danger. But he is more like an Old Testament prophet, calling on us to bewail our wrongful conduct and to go and sin no more.
He starts off with the science. The world’s climate, he reports, is getting warmer. This accurate report is, however, not set in historic context. World climate has grown warmer and cooler at various times in history. Climate change is not some unique historic event. It is the way the world works.
Not this time, Gore says. What’s different is that climate change is being driven by human activity — to wit, increasing carbon dioxide emissions. Which means, he says, that we have to sharply reduce those emissions. But what the scientists tell us is that some proportion of climate change is caused by human activity and some proportion by natural causes — and that they can only estimate what those proportions are. The estimates they have produced have varied sharply. The climate change models that have been developed don’t account for events of the recent past, much less predict with precision events in the future.
To which the prophet replies, with religious intensity, that all debate should be over. Those scientists with inconvenient views should be defunded and silenced. We should replace scientific inquiry with faith. We should have faith that climate change — “global warming” — is caused primarily by human activity. And we should have faith that the effects will be catastrophic, with rising oceans flooding great cities and pleasant plains and forests broiled by a searing sun.
