Salmon Face Upstream Battle as Blueprints for Recovery Are Ignored

As the days get cooler and shorter, millions of salmon are making the arduous journey up the rivers and streams of British Columbia (B.C.) to the spawning grounds where they were born. Waiting for this rich pulse of life from the Pacific Ocean are bears, gulls, wolves, eagles, ospreys, crows, pine martins and dozens of other species. Communities and businesses wait, too. It’s fitting that this time of year also marks the first anniversary of the final report of the Cohen Commission of Inquiry into the Decline of Sockeye Salmon in the Fraser River.
The record decline in sockeye returning to the Fraser River in 2009 provided the initial push for a federal judicial inquiry. Now, four years later, the offspring of those salmon are returning to spawning grounds in dismally low numbers—so low that sockeye salmon fishery closures are widespread.
What happened to Justice Bruce Cohen’s 75 carefully crafted recommendations to rebuild Pacific salmon? What will happen to the industry and communities that depend on them?
The Cohen Commission took three years, 2,145 exhibits, 892 public submissions and 138 days of hearings with 180 witnesses to create its report. The David Suzuki Foundation worked with lawyers at Ecojustice to provide research and testimony to help ensure the inquiry looked into problems within the current management system. With optimism that the federal government was taking the decline of wild salmon seriously, this independent and thorough review created a blueprint for action. What had become a contentious and polarizing issue had a direction forward.
That clear direction, however, has been followed with near silence and little effort from the government. Although politicians say they’re reviewing the report and taking actions “consistent with the recommendations,” the few steps they have taken, such as providing grants for research projects, miss the mark and don’t address the significant issues and opportunities raised by Justice Cohen.
The government’s own Wild Salmon Policy, released in 2005, provides a strong template for salmon conservation and formed a key plank of Cohen’s recommendations. It’s time to bring this policy to life with a cost-itemized plan for determining tasks, delegated responsibility for carrying them out and defined timelines. The government hasn’t even appointed a champion to navigate the complex social, economic, ecological and political world of wild Pacific salmon.
The commission concluded that climate change is one of most troubling stressors for the fish. Salmon are sensitive to water temperature changes and Fraser River waters are projected to warm. Canada must do its part to address climate change if fisheries management is to have any influence on the future of these amazing creatures and all those that depend on them.
Impacts from open net-pen salmon farming also came under the inquiry’s scrutiny. The Department of Fisheries and Oceans (DFO) continues to both promote and regulate the salmon farming industry. Justice Cohen recommended the DFO separate these conflicting mandates and end its responsibility to promote farmed salmon. The DFO should return to what it did well: gathering relevant scientific data, applying it and making it available to the public.
Justice Cohen called for a freeze on fish farm expansion in the Discovery Islands, along an important salmon migratory route, and removal of farms if impacts aren’t addressed by 2020. The commission interviewed British Columbians and received a clear message: don’t risk the future of wild salmon and their important contribution to the fabric of First Nations culture, coastal communities and the whole of Canadian life.
A year has passed, the testimony is in, the evidence heard and $26 million spent. It’s time for action to rebuild wild Pacific salmon runs, so this iconic fish can be shared and enjoyed for generations to come. The fate of wild salmon is too important to be left to languish in government offices. We can’t go on setting up inquiries to review problems and then ignore their recommendations.
This is a serious report with a clear blueprint to address problems. It deserves a serious response. As the salmon struggle to make their miraculous journey up B.C.’s wild rivers, we have to tell Prime Minster Stephen Harper and Fisheries Minister Gail Shea it’s time for the government to get moving too.

The speed and scale of the response to COVID-19 by governments, businesses and individuals seems to provide hope that we can react to the climate change crisis in a similarly decisive manner - but history tells us that humans do not react to slow-moving and distant threats.
A Game of Jenga
<p>Think of it as a game of Jenga and the planet's climate system as the tower. For generations, we have been slowly removing blocks. But at some point, we will remove a pivotal block, such as the collapse of one of the major global ocean circulation systems, for example the Atlantic Meridional Overturning Circulation (AMOC), that will cause all or part of the global climate system to fall into a planetary emergency.</p><p>But worse still, it could cause runaway damage: Where the tipping points form a domino-like cascade, where breaching one triggers breaches of others, creating an unstoppable shift to a radically and swiftly changing climate.</p><p>One of the most concerning tipping points is mass methane release. Methane can be found in deep freeze storage within permafrost and at the bottom of the deepest oceans in the form of methane hydrates. But rising sea and air temperatures are beginning to thaw these stores of methane.</p><p>This would release a powerful greenhouse gas into the atmosphere, 30-times more potent than carbon dioxide as a global warming agent. This would drastically increase temperatures and rush us towards the breach of other tipping points.</p><p>This could include the acceleration of ice thaw on all three of the globe's large, land-based ice sheets – Greenland, West Antarctica and the Wilkes Basin in East Antarctica. The potential collapse of the West Antarctic ice sheet is seen as a key tipping point, as its loss could eventually <a href="https://science.sciencemag.org/content/324/5929/901" target="_blank">raise global sea levels by 3.3 meters</a> with important regional variations.</p><p>More than that, we would be on the irreversible path to full land-ice melt, causing sea levels to rise by up to 30 meters, roughly at the rate of two meters per century, or maybe faster. Just look at the raised beaches around the world, at the last high stand of global sea level, at the end of the Pleistocene period around 120,0000 years ago, to see the evidence of such a warm world, which was just 2°C warmer than the present day.</p>Cutting Off Circulation
<p>As well as devastating low-lying and coastal areas around the world, melting polar ice could set off another tipping point: a disablement to the AMOC.</p><p>This circulation system drives a northward flow of warm, salty water on the upper layers of the ocean from the tropics to the northeast Atlantic region, and a southward flow of cold water deep in the ocean.</p><p>The ocean conveyor belt has a major effect on the climate, seasonal cycles and temperature in western and northern Europe. It means the region is warmer than other areas of similar latitude.</p><p>But melting ice from the Greenland ice sheet could threaten the AMOC system. It would dilute the salty sea water in the north Atlantic, making the water lighter and less able or unable to sink. This would slow the engine that drives this ocean circulation.</p><p><a href="https://www.carbonbrief.org/atlantic-conveyor-belt-has-slowed-15-per-cent-since-mid-twentieth-century" target="_blank">Recent research</a> suggests the AMOC has already weakened by around 15% since the middle of the 20th century. If this continues, it could have a major impact on the climate of the northern hemisphere, but particularly Europe. It may even lead to the <a href="https://ore.exeter.ac.uk/repository/handle/10871/39731?show=full" target="_blank" rel="noopener noreferrer">cessation of arable farming</a> in the UK, for instance.</p><p>It may also reduce rainfall over the Amazon basin, impact the monsoon systems in Asia and, by bringing warm waters into the Southern Ocean, further destabilize ice in Antarctica and accelerate global sea level rise.</p>The Atlantic Meridional Overturning Circulation has a major effect on the climate. Praetorius (2018)
Is it Time to Declare a Climate Emergency?
<p>At what stage, and at what rise in global temperatures, will these tipping points be reached? No one is entirely sure. It may take centuries, millennia or it could be imminent.</p><p>But as COVID-19 taught us, we need to prepare for the expected. We were aware of the risk of a pandemic. We also knew that we were not sufficiently prepared. But we didn't act in a meaningful manner. Thankfully, we have been able to fast-track the production of vaccines to combat COVID-19. But there is no vaccine for climate change once we have passed these tipping points.</p><p><a href="https://www.weforum.org/reports/the-global-risks-report-2021" target="_blank">We need to act now on our climate</a>. Act like these tipping points are imminent. And stop thinking of climate change as a slow-moving, long-term threat that enables us to kick the problem down the road and let future generations deal with it. We must take immediate action to reduce global warming and fulfill our commitments to the <a href="https://www.ipcc.ch/sr15/" target="_blank" rel="noopener noreferrer">Paris Agreement</a>, and build resilience with these tipping points in mind.</p><p>We need to plan now to mitigate greenhouse gas emissions, but we also need to plan for the impacts, such as the ability to feed everyone on the planet, develop plans to manage flood risk, as well as manage the social and geopolitical impacts of human migrations that will be a consequence of fight or flight decisions.</p><p>Breaching these tipping points would be cataclysmic and potentially far more devastating than COVID-19. Some may not enjoy hearing these messages, or consider them to be in the realm of science fiction. But if it injects a sense of urgency to make us respond to climate change like we have done to the pandemic, then we must talk more about what has happened before and will happen again.</p><p>Otherwise we will continue playing Jenga with our planet. And ultimately, there will only be one loser – us.</p>By John R. Platt
