CEES Scientist Geir Ottersen to be a lead author of IPCC Special Report on the Ocean and Cryosphere in a Changing Climate

CEES and Institute of Marine Research scientist Geir Ottersen has been chosen to be a lead author for the IPCC (Intergovernmental Panel on Climate Change) Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC).

Following a thorough nomination and selection process the IPCC has invited 101 experts from 41 countries across the world to work on the report. These lead authors will get together for the first of four joint meetings during October 2-6, 2017. Ottersen, specializing in research on climate effects on marine ecosystems, will be a lead author on a chapter on the Polar Regions.


IPCC was set up in 1988 by the World Meteorological Organization and United Nations Environment Programme to provide policymakers with rigorous and balanced assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation. IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies and are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.

The IPCC author teams reviews the thousands of scientific papers published each year to tell policymakers what we know and don’t know about the risks related to climate change. The IPCC identifies where there is agreement in the scientific community, where there are differences of opinion, and where further research is needed. Much of the information compiled is published in authoritative reports, known as Assessment Reports. In February 2015, the IPCC decided to produce a Sixth Assessment Report (AR6) to be finalized in 2022.

IPCC Special Reports

Special Reports undertake a review and evaluation of cross-disciplinary issues and are more focused than assessments like AR6. The Special Report on the Ocean and Cryosphere in a Changing Climate covers issues related to the ocean and ice-covered areas, including impacts on ecosystems. There are chapters on High Mountain Areas; Sea Level Rise and Implications for Low Lying Islands, Coasts and Communities; Changing Ocean, Marine Ecosystems, and Dependent Communities, and Polar Regions.

Polar Regions
The Polar Regions chapter looks into changes in polar atmospheric and ocean circulation; ice sheets and shelves; snow cover and sea ice, including impacts on ecosystems and their services (like fishing).

In addition to Ottersen Norway will be represented on the SROCC team by Martin Sommerkorn (WWF International) and Miriam Jackson (Norwegian Water Resources and Energy Directorate). The report is scheduled to be finalized in September 2019.


Congratulations, Geir!
