Peaking profiles can achieve global temperature targets with more likelihood at lower costs

The current focus in climate research and policy is on stabilising greenhouse gas concentrations in the atmosphere. By switching to scenarios in which a peak concentration is reached which is then reduced, it is possible to save costs and increase the probability of meeting long-term targets. These are results found by Michel den Elzen and Detlef van Vuuren and published in the most recent edition of the scientific journal Proceedings of the National Academy of Sciences of the USA (PNAS).
