The Argument For Nuclear Energy 2

The first question then is: Does the world need nuclear to avert global warming and/or replace fossil fuels?

And I’m afraid the answer is an unequivocal Yes. It is pretty much inevitable that as fossil fuels dwindle, we are going to use nuclear more. But we must not make the error of seeing it as a solution to these problems. Debate goes on over how long supplies of uranium and other fissile materials will last, but there is no question that like fossil fuels before them, they are finite. Even if they are safer than hydrocarbons – even if they were perfectly safe – they remain a stopgap measure.

The real technical challenge we face is making these non-renewables hold out until renewable energy systems are sufficiently developed to take their place. We have a destination to reach, if you like, and just one tank to get there on. We do not know how long the journey is. There are no filling stations.

And we need to get there as soon as we can. In part of course because both fossil and fissile are environmentally harmful, but mainly because the more of them we use up, the more expensive they will become. A world that is struggling to find sufficient energy just to keep going is not a world that will be able to take on massive engineering projects. If we do not reach that destination while energy is still relatively cheap, we may find that we cannot afford to get there ever. In which case, we face war and starvation on a barely imaginable scale. Energy is, quite simply, the means to survival.

So what I fear most about nuclear power is not its risks, but that it will give us a sense of energy security where none is justified. We need – and we need right now – to focus on the long-term destination, not on finding new ways to keep the unsustainable going that little bit longer.

Is Climate Change, Bitches

After the breakneck pace of events yesterday, I think a change of topic is in order. Though not without noting in passing how Lenihan attempted to shift blame for the bankers’ bonuses onto Fine Gael and Labour this morning. Suddenly, taxing them is an idea he was all in favour of – but alas his hands are tied by the pesky opposition. There’s no shame in this game.

Microcos Climate CartoonGoing back to Sunday’s tirade against the Greens though: I think it’s probably necessary these days, with the rise of “climate scepticism”, to clarify that I am not on the anti-environmental fringe. I don’t know if I’d call myself an environmentalist. I try to avoid labels that end in “ist”, especially in “mentalist”. But I have friends who are Green Party members – well, until Sunday I had – and I agree with a lot of what they think.

There are extremes of environmentalism I find abhorrent; the “Humans are the worst animal ever and the planet would be better if we all died” lobby. There is a bizarre narcissism to that. How can we be worse than Nature? We’re not supernatural beings. What we are, what we do, is an expression of Nature. We do ugly things, as does Nature. The one difference: We know that they’re ugly.

But I think it is wise to try to upset the dynamics of the planet as little as we can. We should care about biological diversity and stability, we should care about the long-term effects of our activities. This seems the moral, responsible thing to do.

And so there is a movement to shirk off that responsibility. They call themselves sceptics, in much the same way that people who want to promote religion over science use the disingenuous label “intelligent design”. More normally, sceptics are people who point out how widely-held personal beliefs are not compatible with scientific knowledge. These people point out how widely-held scientific knowledge is not compatible with their personal beliefs.

The belief in this case seems to be a sort of libertarianism. To these people, climate change is a hoax perpetrated against them by lefty government, an attempt to force a collectivized tyranny onto freedom-loving individuals. The freedom they seem to particularly love is the one to use up oil like nobody’s business.

Last night the UK’s Horizon did an interesting documentary on the fact that professional science is losing the battle against amateur bollocks. The programme had its faults – it kinda forgot to mention that there might be rational grounds to reject GM crops, for one – but it made the point well that we now live in a world full of people who, when faced with the conclusions reached by thousands of dedicated professionals doing decades of gruelling, intricate research, will say “Yes but here’s what I think”.

So here’s what I think: I won’t disagree that there can be a certain irritating piety to “environmental awareness”. I won’t say that political solutions to these problems are never wrong. But the science on the issue is overwhelming. There is little debate about this in the relevant fields today because that debate has been had already. It was pretty much settled more than twenty years ago. The evidence points to human-driven climate change.

If there is any weak link in the argument, it’s where we extend it into the future and predict disaster. There are a lot of unknowns in the future. However, disaster still seems more likely than not.

So: Most people with actual expertise on the subject think it likely that if we keep behaving as we do it will profoundly change our climate, probably making it far less hospitable to humans, to other animals, and to food production.

We should do something about this perhaps.

It’s not comfortable knowledge. We could rest a lot easier if we were ignorant of the idea that the things we do on an everyday basis could be slowly but inexorably leading to extinctions and floods. Nobody wants that. I understand why some are driven to rebel, to deny that this could be true, even invent great conspiracies of people who have an interest in it being true.

But who has such an interest? If there really is such a thing as a “climate change industry”, it is microscopic when placed next to the other one – industry industry. Faking climate change would be in the interest of a few. Pretending climate change isn’t happening, that would be in the interests of a huge number of people – of very wealthy people.

I know which way I’m betting.
