To illustrate this, think about nuclear power. Start with FUKUSHIMA, that dread word. As a result of over-excited media reporting ('great story!' I heard one journalist say) that single word has probably condemned nuclear power for another generation, when in fact the accident produced no radiation-related deaths (and it's doubtful that it will produce a discernable statistical blip in cancers in the future). In a conspiracy which seems almost dishonest, most Green groups failed to acknowledge this – it was too good as propaganda for them to let the facts get in the way – and of course the press never returned to the subject with any correctional follow-up. It became one of those little nuggets of received, and totally incorrect, wisdom: Nuclear=Fukushima=Catastrophe.
That received non-wisdom has persuaded Green Germany to begin decommissioning its nuclear reactors – which means more coal-fired plants. Japan too will probably turn back to coal. Coal is – even Greenpeace would agree – the worst option, though they'd claim that the gap can be filled by renewables. It can't, not now and probably not for decades. In the meantime – and it may be a long, mean time – we'll use coal. It's cheap and very, very dirty.
So the real catastrophe of Fukushima is in the future, waiting for us in the form of vastly increased atmospheric CO2. An emotional over-reaction to a media storm has produced a thoroughly bad decision with longterm global consequences. It's a classic 'how not to' scenario. Is this how our future is going to be – lurching from one panic to another in a daze of 'just coping' and without the benefit of any long-picture wisdom within which to frame our actions? What would help us break out of that trap?
