IPCC Special Report on the Ocean andCryosphere in a Changing Climate(SROCC)

COP24 - December 2018, Katowice, PolandDr. Debra Roberts, IPCC WGII Co-ChairBACKGROUND SROCC• IPCC invited proposals (July 2015) for Special Reports tobe prepared and concluded during AR6 cycle– 7 proposals related ocean and cryosphere• IPCC Panel agreed (43rd Session, April 2016) to consider aSpecial Report on Climate Change and the Ocean andCryosphere• Joint scientific leadership by WGI (Physical ScienceBasis) and WGII (Impacts, Adaptation and Vulnerability)

SCOPING SROCC• Outline developed atScoping Meeting in Monaco(December 2016)• 62 experts were invited todiscuss all aspects of thescope, outline, and contentsof the report• Outline agreed and adopted
by IPCC Panel in April 2017

SROCC• Provide a focussed cross-cutting assessment of:

The role of ocean and cryosphere in the climate system - observed andprojected changes in oceans and cryosphere

Risks, vulnerability, impacts and implications of climate-related oceanand cryosphere change for eco- and human systems



Resilience pathways and adaptation options• Present new and updated information for decision-makers
to inform the design and implementation of appropriate
policies and actions.

their response options, the associated feedback potential• framework that incorporates risk reduction through adaptationand mitigation• wider use of social sciences (incl. anthropology and psychology)
for adaptation (lifestyle choices: decision making, behaviour,
consumption, technologies, societal inertia and transformation)• address tradeoffs and synergies between climate change
adaptation and mitigation link to policy goals (e.g., SDGs, povertyreduction, biodiversity)• Focus on solutions
