SPM in UN and other languages

Translation of the WGI AR5 SPM from English into the other five official languages of the United Nations was done by translators working for the WMO Language, Conference and Publishing Services Department. The assistance of scientists from the WGI chapter teams who acted as scientific translation editors for each language is gratefully acknowledged.
