In 2013, the Chinese Academy of Sciences published a report from the Heartland Institute in order to better understand the public debate and encourage discussion of other views. The preface included a disclaimer that the Academy did not endorse the views in the report, but in June, the Institute announced that the Chinese Academy of Sciences supported their views, and said the publication placed significant scientific weight against climate change. The Chinese Academy of Sciences, responding to the announcement, said "The claim of the Heartland Institute about CAS' endorsement of its report is completely false," clarified that they did not endorse the views of the Institute, and asked for a retraction.
