The Working Group I contribution to the IPCC’s Fifth Assessment Report (AR5) considers new evidence of climate change based on many independent scientific analyses from observations of the climate system, paleoclimate archives, theoretical studies of climate processes and simulations using climate models. It provides a comprehensive assessment of the physical science basis of climate change in 14 chapters, supported by a number of annexes and supplementary material. It includes global and regional climate change projections.
