IPCC fourth assessment report

The Intergovernmental Panel on Climate Change (IPCC) released its Fourth Assessment Report (AR4) in 2007. Since the IPCC considers only published, peer-reviewed science in its assessments, the AR4 did not examine any research published after July 2006. In the years since then, a significant body of new peer-reviewed science has been published, much of which is relevant to policy decisions that will be made before the next IPCC assessment, due in 2014. A brief overview of some key new findings is provided here.
