B.C. launches blueprint to fend off climate’s ‘one-two punch’ on the ocean

Canada’s National Observer, Local Journalism Initiative Reporter

B.C. has unveiled an action plan to tackle the two greatest climate threats to the ocean, coastal communities and marine ecosystems on the West Coast. 

Ocean acidification and hypoxia (OAH), or plummeting oxygen levels, that often occur in tandem with a snowball effect, are spiking due to human-caused greenhouse gas emissions. 

The plan’s goals include strengthening scientific collaboration and research and public awareness on these issues. Finding ways to adapt to or mitigate the negative impacts of OAH is also a priority. 

The province also wants a better understanding of how or if blue carbon — CO2 captured naturally from the atmosphere by marine plants and algae — could or should be used as a natural solution to buffer acidification and hypoxia.

Kelp forests, foundational to coastal ecosystems and Nuu-chah-nulth culture, are at risk

By Alexandra Mehl, Ha-Shilth-Sa, Local Journalism Initiative Reporter

Thriving in cool water temperatures, kelp forests cover over a quarter of the world’s coastlines, with Canada having the longest, says Marissa Ng, Seaforestation Project Coordinator for Ocean Wise. 

Of Canada’s 243,042-kilometre long coastline, British Columbia makes up 25,725.

“In the Pacific Northwest, kelp forests are a foundation species. Similar to salmon, they’re important for the health of the coastal ecosystem,” said Ng. “They’re also foundation species because they’re so abundant up and down the coast and much like forests on land, marine forests – kelp forest – they provide food and shelter for thousands of marine species.”

Unchecked climate change puts Canada’s West Coast in hot water

Canada’s National Observer, Local Journalism Initiative Reporter

Last year was the hottest on record for the ocean, an upward trend only expected to continue as it wreaks havoc on coastal communities and spurs irreversible losses to marine ecosystems. 

Ocean warming has cascading effects, melting polar ice and causing sea-level rise, marine heat waves and ocean acidification, the United Nations’ panel of climate experts made clear on Monday.

Sea-level rise has doubled in the last three decades, reaching a record high in 2021, the Intergovernmental Panel on Climate Change reported. Rising seas, coupled with more extreme weather, are setting the stage for a perfect storm of flooding for coastal communities.

The Quadra Project: Structural Change

Systems are complicated. Indeed, we are just beginning to understand how complicated and unpredictable they are. And they include everything from biological ecologies to global weather.

Systems are integrated. Each part of a system is connected to all the other parts, so that any change in any part influences all the other parts. Usually, small changes are absorbed into the system with little apparent effect. But introduce enough changes, or alter key components, and something unpredictable happens. In Systems Theory, this is called “emergence”, and is marked by a sudden and unpredictable restructuring of the entire system.

Why do oceans matter for climate change?

National Observer, Local Journalism Initiative Reporter

As the climate crisis gets worse, oceans — the planet’s greatest carbon sink — can no longer be overlooked. 

Spanning 70 per cent of the globe, oceans have absorbed nearly a third of the planet-warming greenhouse gas emissions caused by humans and 90 per cent of the excess heat those gases create. 

The heat stored in the Earth’s entire atmosphere is equal to what’s stored in the top few metres of our oceans. If that wasn’t enough, oceans produce more than 50 per cent of the planet’s oxygen and regulate our climate and weather patterns.
