Unlike Ady I do not go in for blanket condemnations of all politicians and business people. I don't let those off the hook though, because most of them can't handle difficult problems beyond their expertise or rapid solving. So they so tend, like the campaigners (of stridency inversely proportional to analysis and understanding) to go for the superficially easy answers.
However, if the scientists themselves have created a trap by suggesting what look like "easy" solutions based on purely numerical models, we can't blame politicians for falling into it too. The computer says… Aye, it does, but what did you ask the computer to compute, and just as importantly, what did you not ask it?
The stark truths emerge from that letter – whatever mitigation measure is proposed that depends on curing the effects, it brings with it enormous problems and costs of its own.Similarly, so do those measures aimed at the cause rather than effect.
Essentially the old adage about free lunches being not, is here more a matter of enormous banquets. Or at least it is for the portion of the world able even to have a sandwich. Whilst developed societies – like our own – can do with less of what we have by want rather than need, there are huge numbers of people who rightly, want what we do genuinely need, and have but too easily take for granted. Do we really need buy our children shiny polyethylene toys? Probably not but let's be brave enough to admit that raises an uncomfortable question about all that shiny metal we want in our own "play-rooms" – yet if we need the shiny blue polyethylene pipe bringing clean, potable water into our homes, then so do those who would not mind it supplying even the village-square tap. Though…. whence the raw materials for the polyethylene?
And those numbers, both of those with the luxury of choice between want and need and those without even what they need, are increasing, but world-wide population is a nettle too difficult and painful to grasp.
There grows alongside that nettle, another, also hinted at in the article. The theory is that presumably we leave hydrocarbon minerals in the ground, rather than risk drastic climate-changes and sea-level rise before depleting them anyway. That's all well and good but coal and oil produce important feed-stocks for a huge range of materials including some of those needed in structures like wind-turbines; and unlike the metals, those materials are not salvageable. With what and how will they be replaced in sufficient quantities at sufficient rates? Can coal and petroleum be refined to extract the "good" without the "bad"? If not, what would we do with millions of tons of left-over coke and inflammable liquid fuels we can no longer burn? How do we perform the tasks those fuels do, including ore-reduction, without bringing yet more serious problems down on our heads?
And so it goes on – one could write a book on the equivalents and ramifications that policy-makers tend to ignore or gloss over by lacking easy answers. The politicians on the whole are not corrupt or incompetent although far too many are desperately ignorant of anything related to science and engineering. Rather, they mean well but have no easy answers because there are no easy answers.
Once again we are back to the free banquet question, and the dark question if frankly, whatever we do, we are doomed or damned or both; though maybe not us personally, nor even our grand-children.
The trap those scientists have seen is far deeper and less escapable than they describe.
