AFP obtained a copy of the draft report's 20-page Summary for Policymakers, which is subject to revision by governments before release on November 18.
A series of natural catastrophes around the world has boosted the need to determine whether such events are freaks of the weather or part of a long-term shift in climate. Read the full report here.
