How oceans could be used for carbon capture on a big scale

How oceans could be used for carbon capture on a big scale

Our planet is changing. So is our journalism. This weekly newsletter is part of a CBC News initiative entitled "Our Changing Planet" to show and explain the effects of climate change. Keep up with the latest news on our Climate and Environment page.

This week:

Scientists have said we're poised to overshoot the 1.5 C warming target enshrined in the Paris Agreement, and that in order to return to 1.5 C by 2100, we would need to remove vast amounts of carbon dioxide from the atmosphere.

Carbon capture from smokestacks or the air, using technology and tree planting, has received a lot of attention and funding. But last week, a few hundred scientists around the world argued that more attention should be paid to carbon capture in the ocean.

"The ocean's carbon content is 50 times larger than what is in the atmosphere. Its sheer size also means that ocean-based climate solutions can be scaled to significantly mitigate climate risk," they wrote in a letter posted on the web page of Ocean Visions, a non-profit umbrella group for universities and oceanographic institutions focused on ocean-climate restoration solutions.

The problem? Even scientists know little about the effectiveness, risks or impacts of ocean carbon capture solutions. 

Kate Moran, president and CEO of Ocean Networks Canada and a spokesperson for the scientists who wrote the letter, said more information is crucial for making policy decisions about ocean carbon capture.

"We do need to, as a collective community, get behind research needed to understand these issues, and it's pretty urgent," she said in an interview from the Canadian Coast Guard ship Tully off the coast of B.C., where she is doing some of that research.

The letter was signed by a number of scientists from the Canadian firm Planetary Technologies, including its chief ocean scientist, Will Burt. Planetary Technologies ran its first ocean tests of its carbon capture technology in Halifax harbour this week (see photo above).

Burt hopes the letter helps the public "build some confidence that what we're doing is … widely believed scientifically to be worth exploring."
