The quiet crossing of ocean tipping points
In a recent 'Perspective' published in Proceedings of the National Academy of Sciences of the United States of America, Heinze et al. describe that high-probability ocean tipping points (due to warming, acidification, and deoxygenation) can aggregate to global issues of the same extent as potential climatic tipping points that lead to singular catastrophic events. Research approaches and mitigation options to tackle the ocean tipping points are presented. The authors are the project directors/managers, the core theme leaders, and stakeholder reference group members of the European Horizon2020 project ‘Our common future ocean in the Earth system - quantifying coupled cycles of carbon, oxygen, and nutrients for determining and achieving safe operating spaces with respect to tipping points (COMFORT)'.
