Excuse me if I make a few clarifications. In reality, the Intergovernmental Panel on Climate Changes Summary for Policymakers for their 5th Assessment Report was initially written by climate scientists for politicians. The language of the IPCCs Summary for Policymakers was then amended by politicians during days of negotiations in Stockholm prior to publication.
Additionally, the vast majority of the scientific research reflected in that document was funded by governments. As a result, the IPCC Summary for Policymakers presents only research efforts that adhere to the agendas of the political entities that financed it.
Thanks for the text & link.
