The Copenhagen Diagnosis - Interim Climate Science Report

A team of climate scientists has produced The Copenhagen Diagnosis, a summary of peer-reviewed science on the anticipated impacts of anthropogenic climate change.

The purpose of this report is to synthesize the most policy-relevant climate science published since the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4). Since then, many hundreds of papers have been published on a suite of topics related to human-induced climate changes. The report serves as an interim evaluation of the evolving science, and as a handbook of science updates that supplements the IPCC AR4. (IPCC AR5 is not due for completion until 2013.)

Despite recent revelations and controversy over some data sets and scientists’ actions, the report authors believe that world leaders still have plenty of topics to discuss during the UN Climate Change meeting that begins next week in Copenhagen.
