Ocean threats: acidification, deoxygenation, warming, heatwaves. Do we have anything useful to bend, change, or reverse the results? This brochure, conceived to advocate and educate at the UNFCCC COP27 meetings, summarises these threats and how various solutions (explained within) can actually help protect the ocean as Nature-based Solutions, if correctly constructed, and the existing and emerging financial mechanisms and institutions that can build and fortify these solutions.
