 The Copenhagen Consensus that Lomborg later organized concluded that combating global warming does have a benefit but its priority compared to other issues is "poor" (ranked 13th) and three projects addressing climate change (optimal carbon tax, the Kyoto protocol and value-at-risk carbon tax), are the least cost-efficient of its proposals.Lomborg concludes his book by once again reviewing the Litany, and noting that the real state of the world is much better than the Litany claims.According to Lomborg, this discrepancy poses a problem, as it focuses public attention on relatively unimportant issues, while ignoring those that are paramount.
