I find it difficult to find fault with its conclusion:
"Such an understanding is essential for two quite different reasons. First, it is a basic issue of justice. The dead should be remembered and their families and friends should understand the factors involved in their deaths. Second, it seems likely that the numbers of people killed by climate change has been significantly underestimated. This means that, in addition to issues of the morality of equating human lives with the time spent waiting in airport queues, such cost-benefit analyses used to shape government policy with major climatic impacts, such as building a new runway at Heathrow, are likely to be biased by underestimating the cost in human lives of such decisions."
