I don't know whether I agree with Trump or Obama about Climate Change ... perhaps a rough description of my feelings would be "I'm not competent to judge disputes in the Natural Sciences, but since most of those who are, take the Obama view, I suppose it's probably safest to assume that there might be something in it rather to leave a future generation to regret that we missed an opportunity". Similarly in the question of whether to praise or criticise Laudato si.
It's really a matter of age. One sees fashions come and go. Did I say 'Fashions'? I meant 'Certainties'.
When I was a small boy, they built a nuclear power station near the part of Essex where I grew up and was educated. (It was at Bradwell on Sea, on a desolate skylark-ridden part of the Essex marshes, not far from the ruins of a Roman 'Saxon Shore' fort called Othona, where S Cedd built within his monastic episcopium one of the oldest churches in England.)
I remember our Physics master talking to us in a self-important way (much use of the pronoun 'we') which seemed to imply that he was himself personally responsible for the anatomy and the properties of the atom. He solemnly assured us that, once this power station had paid off the initial costs of its construction, it would supply free energy for ever.
Tiny that I was, I thought something like "If a man is stupid enough to believe that, he will be stupid enough to believe anything". Although the School had rules designed to ensure that each of us made a 'balanced' selection of academic options, I took steps to ensure that I got out of this daft, sci-fy fantasy subject as soon as I could. This included getting 3% in the next Physics examination, neatly matching the 97% I had got the previous term. Believe me, achieving such delicate and satisfying patterning is not easy, although I say it myself.
Yes, I was as nasty and opinionated as a schoolboy as I am now that I have become a wrinkly.
Now we have just been told that the hideous costs of decommissioning and rendering safe that generation of nuclear power stations will be far, unbelievably far, beyond all the other combined disastrous costs mounting up from all the many other bungled governmental decisions of the past.
Part of the problem is, apparently, that the wise infallibilists who designed and ran these poisonous institutions did not even bother to make records of how and where they stored their 'used rods', or whatever the silly phrase is.
