Day 3 - Sixth Assessment Report (AR6) process (including focus on SR on Oceans and Cryosphere)
1. Sixth Assessment Report (AR6): IPCC Special
Report on the Ocean and Cryosphere in a
Changing Climate (SROCC)
Joy Jacqueline Pereira
Vice Chair, IPCC Working Group 2
2. The role of the IPCC is …
“… to assess on a comprehensive, objective, open and transparent basis the
scientific, technical and socio-economic information relevant to understanding
the scientific basis of risk of human-induced climate change, its potential
impacts and options for adaptation and mitigation.”
“IPCC reports should be neutral with respect to policy, although they may need to
deal objectively with scientific, technical and socio-economic factors relevant to
the application of particular policies.”
