“The most arresting statistic that Lomborg produces is this. It is well known that meeting the Kyoto treaty on carbon-dioxide reduction will delay global warming by six years at most by 2100. Yet the annual cost of that treaty, in each year of the century, will be the same as the cost – once – of installing clean drinking water and sanitation for every human being on the planet. Priorities, anyone?” – Matt Ridley, in an excellent summary of the environmental movement’s over-reaction to Bjorn Lomborg’s book, “The Skeptical Environmentalist.”
