PC011:
Towards a 1.5oC World: The Ocean Response


Session ID#: 28536

Session Description:
The Paris Agreement (COP21) has set an aspirational goal of limiting global surface warming to 1.5oC. This goal requires immediate action, with almost all future scenarios indicating that carbon dioxide removal or other geoengineering approaches will be needed. Irrespective of geoengineering measures, emissions must peak in a little over a decade and then rapidly decrease to become zero or even net negative. Given the prominent role of the ocean in storing emitted carbon dioxide and excess heat, the exploration of the potential response of the ocean to a drop in or even negative emissions is of scientific interest and of societal relevance. This session welcomes abstracts exploring the response of the ocean under scenarios aiming towards a 1.5oC world and how it may feed back to the other components of the Earth system. Relevant issues may include hysteresis effects in ocean circulation or sea-ice, the response of the ocean carbon and other biogeochemical cycles, ecological impacts, and potential unanticipated impacts of geoengineering measures.
