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.

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.

Feds and First Nations gearing up to host global ocean conservation summit

National Observer, Local Journalism Initiative Reporter

Ottawa and First Nations in B.C. are looking to amplify oceans as the best way to turn the tide on the twin spectres of biodiversity collapse and climate change, says federal Minister of Fisheries and Oceans Joyce Murray. 

Canada and West Coast First Nations — the Musqueam, Squamish and Tsleil-Waututh — are hosting the fifth International Marine Protected Areas Congress (IMPAC5) in Vancouver to spur change on the international protection of marine ecosystems, Murray told Canada’s National Observer.

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.

Why Bottom Trawling is a climate disaster

By Marc Fawcett-Atkinson, Canada’s National Observer, Local Journalism Initiative Reporter

Bottom trawling, a common fishing practice where large nets are dragged along the sea floor, is exacerbating the climate crisis, a new study has found.
