This Synthesis Report is based on the assessment carried out
by the three Working Groups (WGs) of the Intergovernmental Panel
on Climate Change (IPCC). It provides an integrated view of climate
change as the final part of the IPCC

This report provides the most comprehensive and up-to-date scientific assessment of the impacts of climate change, the vulnerability of natural and human environments, and the potential for response through adaptation. It evaluates evidence that recent observed changes in climate have already affected a variety of physical and biological systems and concludes that these effects can be attributed to global warming.
