Sucker's Bets for the New Century

[phantom power]

For the ten thousand years of human civilization, we've relied on the planet's basic physical stability. Sure, there have been hurricanes and droughts and volcanoes and tsunamis, but averaged out across the Earth, it's been a remarkably stable run. If your grandparents inhabited a particular island, chances were that you could too. If you could grow corn in your field, you could pretty much count on your grandkids being able to do likewise. Those are now sucker's bets - that's what those predictions about environmental refugees really mean.

Here's another way of saying it: In the last century, we've seen change in human societies speed up to an almost unimaginable level, one that has stressed every part of our civilization. In this century, we're going to see the natural world change at the same kind of rate. That's what happens when you increase the amount of heat trapped in the atmosphere. That extra energy expresses itself in every way you can imagine: more wind, more evaporation, more rain, more melt, more... more... more.

And there is no reason to think we can cope. Take New Orleans as an example. It is currently pro forma for politicians to announce that it will be rebuilt, and doubtless it will be. Once. But if hurricanes like Katrina go from once-in-a-century storms to once-in-a-decade-or-two storms, how many times are you going to rebuild it? Even in America there's not that kind of money - especially if you're also having to cope with, say, the effects on agriculture of more frequent and severe heat waves, and the effects on human health of the spread of mosquito-borne diseases like dengue fever and malaria, and so on ad infinitum. Not to mention the costs of converting our energy system to something less suicidal than fossil fuel, a task that becomes more expensive with every year that passes.

Our rulers have insisted by both word and deed that the laws of physics and chemistry do not apply to us. That delusion will now start to vanish. Katrina marks Year One of our new calendar, the start of an age in which the physical world has flipped from sure and secure to volatile and unhinged. New Orleans doesn't look like the America we've lived in. But it very much resembles the planet we will inhabit the rest of our lives.

I think it's quite likely that we'll see a Katrina every year or two, not every decade or two. Last year's Ivan was quite similar to Katrina. A bit less powerful on (american) land-fall, and it hit farther east, but it mowed down Cuba as a cat-5.
