Multiple lines of evidence show that carbon-intensive human activity has destabilized critical parts of the Earth system that determine our climate. To date, the ocean has absorbed 40% of fossil fuel emissions through processes collectively known as the "ocean carbon pump", and 90% of the heat from human-induced global warming. In response, the ocean is changing at an uncertain rate and its capacity to buffer human impact could potentially fail, critically exacerbating climate change and potentially compromising net-zero ambitions.Human adaptation to a changing climate urgently requires better understanding of ocean processes in response to this crisis. The Transforming Climate Action initiative will resolve, identify and demonstrate the transformative solutions required. We propose three interconnected research themes focused on the North Atlantic, which absorbs 30% of global ocean carbon, as we co-produce transdisciplinary and socially-relevant research with Indigenous and non-Indigenous communities, governments, and international partners to inform climate action for Canada:1. Through intensified and intelligent observation of key ocean processes in the North Atlantic, we will reduce critical uncertainties at the ocean-climate nexus, including enhanced observation of air-sea carbon fluxes, deep convection, and seafloor carbon absorption. Recent technological advances will support a higher-level synthesis of ocean data than previously possible. This synthesis will feed directly into climate policies.2. With rigor made possible by reduced uncertainty (Theme 1), as well as engineering- and nature-based solutions to lower the carbon footprint of ocean industries and boost clean technologies for observation and monitoring, we will develop novel approaches to address climate change through co-designed mitigation actions, including acceleration of natural and artificial carbon absorption in the ocean. 3. We will develop new understanding and practical methods to bolster justice and equity within adaptation at the Ocean-Climate-People nexus. Collaboration with Indigenous and costal communities, novel decision-making, governance and policy approaches will support more equitable and enduring adaptation responses for a transition to a carbon neutral economy. Transformative knowledge mobilization will develop meaningful, impactful, and usable communication and investigate approaches to education for the empowerment needed to translate knowledge into action.

多种证据表明，碳密集型人类活动已经破坏了决定气候的地球系统关键部分的稳定。迄今为止，海洋通过统称为“海洋碳泵”的过程吸收了 40% 的化石燃料排放量，以及人类引起的全球变暖的 90% 的热量。作为回应，海洋正在以不确定的速度发生变化，其缓冲人类影响的能力可能会失败，从而严重加剧气候变化，并可能损害净零雄心。人类适应不断变化的气候迫切需要更好地了解海洋过程以应对这场危机。气候转型行动倡议将解决、确定和展示所需的变革性解决方案。我们提出了三个相互关联的研究主题，重点关注北大西洋，北大西洋吸收了全球海洋碳的 30%，我们与土著和非土著社区、政府和国际合作伙伴共同开展跨学科和社会相关的研究，为加拿大的气候行动提供信息：1。通过对北大西洋关键海洋过程的强化和智能观测，我们将减少海洋与气候关系的关键不确定性，包括加强对海气碳通量、深层对流和海底碳吸收的观测。最近的技术进步将支持比以前更高水平的海洋数据综合。这一综合将直接纳入气候政策。2．通过减少不确定性（主题 1），以及基于工程和自然的解决方案来降低海洋产业的碳足迹并促进清洁观测和监测技术的发展，我们将通过共同设计的缓解行动（包括加速海洋中的自然和人工碳吸收）开发应对气候变化的新方法。 3. 我们将发展新的认识和实用方法，以促进海洋-气候-人类关系适应过程中的正义和公平。与土著和沿海社区的合作、新颖的决策、治理和政策方法将支持更公平和持久的适应对策，以实现向碳中和经济的过渡。变革性的知识动员将发展有意义、有影响力和可用的沟通，并研究教育方法，以赋予将知识转化为行动所需的权力。
