The Paris Agreement target of limiting global surface warming to 1.5–2∘C compared to pre-industrial levels by 2100 will still heavily impact the ocean. While ambitious mitigation and adaptation are both needed, the ocean provides major opportunities for action to reduce climate change globally and its impacts on vital ecosystems and ecosystem services. A comprehensive and systematic assessment of 13 global- and local-scale, ocean-based measures was performed to help steer the development and…

Warming world, changing ocean: mitigation and adaptation to support resilient marine systems

The “business-as-usual” future is expected if current trends continue, while an alternative future could be realised if society were to effectively use available data and knowledge to push as far as possible towards achieving the UN SDGs.

Ocean-based climate actions recommended by academicians from Europe and China

Ocean acidification, deoxygenation and sea level Rise impacted by global warming intertwined with anthropogenic activities have resulted in tremendous ecological losses at species, diversity and

The Potential for Ocean-Based Climate Action: Negative Emissions Technologies and Beyond

The effectiveness, feasibility, duration of effects, co-benefits, disbenefits, cost effectiveness and governability of four ocean-based negative emissions technologies (NETs) are assessed in

Avoiding the “Great Filter”: An assessment of climate change solutions and combinations for effective implementation

Global climate temperatures have unmistakably risen, and naturally occurring climate variability alone cannot account for this trend. Human activities are estimated to have caused about 1°C of global

It is argued that a two-pronged approach is needed to achieve a technical integration of ocean acidification across the targets to be included in the post-2020 framework, and a reframing of the issue as a 'biodiversity problem', so as to highlight the synergies between existing biodiversity work and action needed to address ocean Acidification.

The Global Integrated World Ocean Assessment: Linking Observations to Science and Policy Across Multiple Scales

In 2004, the United Nations (UN) General Assembly approved a regular process to report on the environmental, economic and social aspects of the world’s ocean. The Regular Process for Global Reporting

Climate change, tropical fisheries and prospects for sustainable development

Tropical fisheries substantially contribute to the well-being of societies in both the tropics and the extratropics, the latter through ‘telecoupling’ — linkages between distant human–natural



Marine reserves can mitigate and promote adaptation to climate change

It is concluded that marine reserves are a viable low-tech, cost-effective adaptation strategy that would yield multiple cobenefits from local to global scales, improving the outlook for the environment and people into the future.

The right incentives enable ocean sustainability successes and provide hope for the future

Evaluating conservation tools by their ability to align incentives of actors with broader goals of sustainability is an underused approach that can provide a pathway toward scaling sustainability successes, and it is suggested that getting incentives right matters.

Mitigating Local Causes of Ocean Acidification with Existing Laws

Policy options by which local and state governments—as opposed to federal and international bodies—can reduce these local and regional “hot spots” of ocean acidification are described.

Taking Action Against Ocean Acidification: A Review of Management and Policy Options

The assumption that fighting acidification is mainly, but not only, about reducing CO2 emissions is investigated, and the leeway that this emerging problem may open in old environmental issues is explored, to help marine life face unavoidable acidification.

Large benefits to marine fisheries of meeting the 1.5°C global warming target

Limiting temperature increases to 1.5°C substantially improved catch potential and decreased turnover of harvested species and provide further support for meeting the goal of limiting climate warming, which should improve fisheries across the globe.

Mitigating climate change through restoration and management of coastal wetlands and near-shore marine ecosystems : challenges and opportunities

There is overwhelming consensus amongst climate scientists that the Earth's warming in recent decades has been caused primarily by human activities that have increased the amount of greenhouse gases

Natural climate solutions

It is shown that NCS can provide over one-third of the cost-effective climate mitigation needed between now and 2030 to stabilize warming to below 2 °C.
