Bjorn Lomborg's analysis of the cost of climate change correctly exposes a serious fiction in most government's rhetoric - that current plans, which will do very little to address the problem, may well be a waste of money. Politicians need to be honest that, on some measures, the monetary costs and benefits of inaction and effective action may well be very similar. The real issue is what this view of cost misses out, the damage and destruction that can't be quantified or, from a purely economic standpoint is worth very little because it happens to poor people. The truth is that the people at the top of the economic and political systems have no motivation to take any action, they won't lose out and many may even benefit from the crisis. That is why can't leave it up to them.
