IPCC's Video on the Working Group I report
The IPCC (Intergovernmental Panel on Climate Change) has summed up in a very effective video the conclusions of the Working Group, made up of 259 scientists from 39 countries, who study the scientific basis of climate change. This document was approved on September 27, 2013 and is part of the Fifth Assessment Report. The other parts will be made available with subsequent approval of the other two contributions of the working groups and of the 2014 summury report.
