• Climate policy-making or negotiations
![Page 4: What is the IPCC?Fifth Assessment Report (2013/14) AR5 Synthesis Report AR5 Synthesis Report AR5 statistics •836 authors from 85 countries •(incl 301 DC/EIT, 179 women, 529 new)](https://reader034.fdocuments.net/reader034/viewer/2022051910/5fffd2c2cbe5dd56487b19cc/html5/thumbnails/4.jpg)
The role of the IPCC is …
• Assess the scientific, technical and socio-economic
information relevant to human-induced climate
change …
• … so that we understand its risks and potential
impacts …
• … and options for preventing climate change and
adapting to it.
