The report included contributions from over 40 experts from 11 countries, and is meant to guide policymakers.
Its lead authors included David King, the UK foreign secretary's climate change representative; Daniel Schrag, a member of US President Barack Obama's council of advisors on science; and Zhou Dadi, a member of the China national expert committee on Climate Change.
