Oceans in Crisis: IPSO’s Call for North American Action

The health of the world’s oceans has begun to deteriorate at an alarming pace. A comprehensive assessment led by the International Programme on the State of the Ocean indicates that sea systems are facing multiple, intertwining threats that could push coastal and open-ocean ecosystems toward critical tipping points. The message from scientists is clear: rising temperatures, shifting currents, and changing chemistry are reshaping habitats and the life they sustain, with consequences that ripple through fisheries, weather patterns, and coastal communities.

Climate change is only part of the problem. The oceans are pressured from overfishing, plastic and chemical pollution, nutrient-rich runoff from land, and offshore activities that disrupt marine life. In North America’s waters, these pressures converge with busy shipping lanes, nutrient inputs from agriculture, and extreme weather, amplifying harm to sensitive habitats and the species that rely on them.

The study claims “conditions are ripe for the sort of mass extinction event that has afflicted the oceans in the past.”

That kind of news is hard to swallow. For years the ocean has been assumed to be a vast, resilient shield against climate change, a remarkable resource that keeps our planet regulating climate and supporting life. Yet the latest findings emphasize vulnerabilities that demand attention now rather than tomorrow.

Taken as a whole, the ocean has been taken for granted as a public good that quietly supports humanity. It regulates climate, absorbs excess heat, helps buffer storms, and sustains livelihoods across coastal towns and commercial fleets. In addition to its role as a climate moderator, the ocean provides food, jobs, and cultural value to communities from the Atlantic and Pacific coasts to the Gulf and beyond. If the system weakens, the ripple effects will touch energy security, tourism, and the stability of coastal economies in Canada, the United States, and beyond.

Coral reefs, in particular, bear the brunt of higher water temperatures, becoming stressed and more vulnerable to disease and bleaching. They are also undermined by overfishing, which removes key species that help reefs cope, and by pollution that darkens waters and feeds harmful algal blooms. The result is a slower, less diverse reef system that can no longer support the full suite of organisms upon which many coastal communities depend.

IPSO is preparing a set of five papers that urge world governments to adopt concrete actions and policies. The papers call for a strong, coordinated approach to cut emissions, protect valuable habitats, and secure stable livelihoods for people who depend on healthy oceans. They emphasize the need for regional leadership and international cooperation to preserve the health of global seas for future generations.

  • Phase out factory emissions that drive up atmospheric carbon dioxide and support a rapid transition to cleaner energy, greater efficiency, and zero-emission technologies wherever feasible.
  • Improve how fisheries are governed worldwide to halt overfishing, protect vulnerable populations, and ensure resilient harvests that communities can rely on over the long term.
  • Develop a prioritized plan to reduce the most harmful pollutants, including industrial chemicals and agricultural runoffs, while strengthening monitoring and enforcement.
  • Negotiate a new, robust agreement for sustainable fishing in the high seas, with clear rules, accountable compliance, and transparent reporting.

The question now is what action can be taken locally and globally. The report invites readers to share practical ideas and actions that can help keep the seas healthy for current and future generations.
