Building resilience to climate ocean change along the West Coast of North America: insights for international partners

The signs of the climate crisis are everywhere – droughts, wildfires, extreme heat waves, flooding, and more intense hurricanes. We can no longer ignore the growing costs of climate change on people and our communities.

And there can be no action to fight climate change and limit its impacts without including the ocean. The ocean plays an essential role in climate regulation and provides solutions for adaptation and mitigation to address climate-driven impacts. Ocean-climate action must reduce those impacts and build resilience for ecosystems and coastal communities dependent upon a healthy ocean. Our ocean and coasts can help us meet our climate goals.

Up and down our coastlines, we have already experienced the ravages of climate-ocean change including sea-level rise, ocean acidification, ocean warming and reduced oxygen levels. Recent marine heat waves and harmful algal blooms have killed or poisoned shellfish and marine mammals and caused temporary closures to important commercial fisheries including Tribal, First Nation and recreational harvesting. Ocean acidification is damaging shell-forming species, impacting shellfish aquaculture production and ecosystem health.  Iconic species like salmon and orcas and important habitats like kelp forests are suffering dramatic declines due to climate-driven impacts.

The Intergovernmental Panel on Climate Change (IPCC) recently reported that sea-level rise, ocean acidification, ocean warming and deoxygenation will continue to increase in the 21st century — how fast and how much change we experience are dependent on future emissions scenarios. The West Coast has experienced a preview of the changes to come if we do not act urgently and aggressively to reduce our greenhouse gas emissions.

The good news is that if we act now — we can make a difference. Our leaders have banded together to take action. California Governor Gavin Newsom, Washington Governor Jay Inslee, Oregon Governor Kate Brown and the Premier of British Columbia John Horgan support a regional partnership called the Pacific Coast Collaborative to advance climate policies, build a clean energy economy and infrastructure, and increase our resilience to impacts already occurring.

We’ve helped synthesize scientific understanding by facilitating communication among regional scientists, managers and policymakers and are increasing and coordinating investments for regional research, monitoring and forecasting.  These efforts will provide information on the status and trends of climate impacts on the world’s oceans. For ocean acidification, enhancing monitoring to better couple biological and chemical data has the potential to offer decision-makers with information needed to develop policy in response to worsening conditions that threaten the stability of the affected ecosystems.

On that front, we continue to learn from each other and share information such as the recently released publication, “Ocean Acidification: Insight for Policy and Integrated Management” which examines the challenges and opportunities facing state and regional governments in responding to ocean-climate impacts. The issue includes 42 authors representing government and non-government institutions across U.S. nine states.

And we are having global impact. In 2016, we launched the International Alliance to Combat Ocean Acidification (OA Alliance) and issued a call to national, subnational and civil society to protect oceans from the impacts of rising carbon emissions and help do our part to meet the goals of the Paris Climate Agreement. Today, we have over 100 members including nations such as Fiji, Chile, New Zealand, France, Canada and Sweden along with many U.S. states, Tribal government and First Nations, cities and ports. Members are committed to addressing ocean acidification and elevating the importance of integrating the ocean in climate policy frameworks such as such as the United Nations Framework Convention on Climate Change (UNFCCC) and the United Nations 2030 Sustainable Development Agenda (UNSDG 13 and 14).

As part of our leadership role at COP26—we are calling for bold ocean-climate actions that:

(1) Implement aggressive climate action through carbon emissions reductions. Achieving ambitious emission reductions targets is the most important step in turning the tide of climate impacts on our ocean.

(2) Create ongoing opportunities to integrate the ocean into international climate policy efforts, including those as recommended by the UNFCCC Climate and Ocean Dialogue. Sharing information on ocean solutions and actions can help us all do more to reduce ocean and coastal impacts and build resilience faster.

(3) Increase international and domestic finance for science-based ocean mitigation and adaptation strategies—including the robust implementation UN SDG 14.3, which requires targeted monitoring at regional scales to minimize and address ocean acidification.

(4) Integrate ocean actions into climate policies at the domestic level, including through the creation of OA Actions Plans, enhanced Nationally Determined Contributions (NDCs) or other frameworks.

(5) Ensure Tribal sovereigns, First Nations and Indigenous peoples’ knowledge, leadership and priorities as well as those of overburdened communities are reflected across ocean and coastal climate change response strategies and processes, including consideration of tribal treaty rights and responsibilities.
