Ocean-Based Climate Solutions Make Waves Ahead of Climate Summit

As countries around the world attempt to make their economy more green, they’re turning to the ocean for climate solutions. On Tuesday, Special Presidential Envoy John Kerry and Energy Secretary Jennifer Granholm, participated in a virtual event to demonstrate the advantages of “blue” climate initiatives.  Leaders from around the globe attended the event — the UK’s Environment Minister, Chile’s Foreign Minister, and the Prime Minister of Fiji.  Kerry announced the U.S. will spearhead several ocean-based initiatives combatting climate change, including decarbonizing the global shipping sector by 2050, creating three massive marine reserves near Antarctica, and helping small island nations adapt to sea-level rise and other climate impacts.

Why this Matters:  Ocean-based climate strategies tend to take a back seat to emissions cuts in the transportation and fossil fuel sectors. But the ocean could be pivotal to lowering the global temperature — a 2019 study found that ocean-based projects could reduce as much as 21% of carbon emissions. These solutions include offshore carbon sequestration, floating solar panels, and tidal energy. President Biden has already begun to push for offshore wind, recently green-lighting a massive project near Massachusetts.  Kerry pledged to make ocean solutions a major “leg” of the climate meeting later this year.

A Source of Solutions

Policymakers also want to consider the way that climate change adversely affects the ocean before diving headfirst into ocean-based climate initiatives. A new U.N. report suggests that the ocean absorbs 23% of annual emissions of human-caused carbon dioxide, which causes the water’s pH levels to lower and makes it too acidic for marine life to thrive. Moreover, some want to use deep seabed mining to find metals like copper, cobalt, and nickel for clean energy technology, even though it could harm the ocean’s many ecosystems

As we have reported, one of the most ambitious ocean conservation projects ever, called the Blue Nature Alliance, launched yesterday.   More than a half-dozen organizations agreed to work together to create fully protected marine reserves of parks covering an ocean area (7 million square miles), which is twice the size of the continental U.S. and larger than South America.  This effort will also provide benefits for combatting climate change by strengthening ocean health generally from other “stressors” like pollution and overfishing and illegal fishing.

Jane Lubchenco, the top White House climate scientist, told Axios: “There’s no doubt that the ocean has been a victim of climate change. What the new science is telling us, and these leaders are now incorporating into their actions, is that the ocean can also be a powerful source of solutions.”

by Ashira Morris, ODP Staff Writer In Cispatá on Colombia’s Caribbean coast, scientists have calculated just how much carbon a mangrove forest stores. Up until now, that number has treated mangroves like trees on land — missing more than half of their carbon store in the soil under trees. The calculation in Cispatá estimates the […]

Seaing Stars in the Marine Lab

Over the last decade, nearly 91% of the sunflower sea star population has been wiped out, landing the species a “critically endangered” categorization last year. The sea stars, which have 24 arms, are an important part of the underwater food web: they keep kelp forests healthy by feeding on sea urchins. 

Why This Matters: Between rising temperatures, overfishing, ocean acidification, among other harms, people have thrown the U.S. West Coast marine ecosystem off the balance.

One Cool Thing: A New Wave Of Eco-Based Video Games

Video gaming experts say that game design is now shifting towards specific environmental issues. Since games are designed by young people, it is not surprising that eco-based storylines like climate change and ocean exploration are coming into vogue.  For example, the BBC Blue Planet II nature documentary inspired a video game called Beyond Blue, in which […]
