The ocean and cryosphere play a key role in the Earth system regulating global climate and weather. For example, uptake of heat and carbon into the ocean has so far restricted the magnitude of anthropogenic warming at the Earth?s surface. The extra heat and carbon absorbed by the ocean results in warming of the water column, increased sea level, acidification and deoxygenation, with consequent impacts on life in the ocean, on ecosystem services (e.g. fisheries) and on human communities living by the sea, and also strongly affecting global climate. As part of its Sixth Assessment Cycle, the Intergovernmental Panel on Climate Change (IPCC) has produced a Special Report on the Ocean and Cryosphere in a Changing Climate(SROCC), which will bewas released in September 2019 after two years of preparation by around 100 experts from 30 countries selected by the IPCC. The SROCC assessed the multiple observed and projected changes in the ocean and the cryosphere in a continuing warming climate evaluating new information since the IPCC Fifth Assessment Report (AR5; IPCC 2013) and it was developed under the joint scientific leadership of IPCC Working Group I (The Physical Science basis) and Working Group II (Impacts, Adaptation, and Mitigation), providing fundamental connections between physical changes and how natural and human communities will be impacted by them, assessing strategies to respond and adapt to ongoing and future risks.We will present and discuss the background and key findings of the SROCC.
