Humans are already adapting to climate-driven changes in marine systems, and while further adaptations are required even under low-emission scenarios , transformative adaptation will be essential under high-emission scenarios . Low-emission scenarios permit a wider array of feasible, effective and low-risk nature-based adaptation options  . Under high-emission scenarios, adaptation options  are more uncertain and require transformative governance changes . Transformative climate adaptation will reinvent institutions to overcome obstacles arising from historical precedents, reducing current barriers to climate adaptation in cultural, financial and governance sectors . Without transformation, global inequities will likely increase between regions  and conflicts between jurisdictions may emerge and escalate.
