Climate engineering would alter the oceans, reshaping marine life – our new study examines each method’s risks

14 January 2026, Kelsey Roberts, Daniele Visioni, Morgan Raven, Tyler Rohr, theconversation.com

Scientists, governments, and a growing number of startups are exploring ways to remove carbon dioxide from the atmosphere or at least temporarily counter its effects. But these climate interventions come with risks—especially for the ocean, the world’s largest carbon sink, where carbon is absorbed and stored, and the foundation of global food security. In a new study, a team of researchers analyzed how different types of climate interventions could affect marine ecosystems, for good or bad, and where more research is needed to understand the risks before anyone tries them on a large scale. They found that some strategies carry fewer risks than others, though none is free of consequences.

Woods Hole Tests Ocean Alkalinity Enhancement in Gulf of Maine for CO2 Capture

12 August 2025, Victoria Mossi , www.webpronews.com

Scientists from Woods Hole Oceanographic Institution will test ocean alkalinity enhancement by adding 20 tons of sodium hydroxide to the Gulf of Maine, aiming to boost CO2 absorption and combat climate change. While promising for carbon sequestration, it raises ecological and ethical concerns. Success could advance geoengineering, but rigorous monitoring is essential. Collaborations with institutions like those involved in the Arctic Ocean 2050 program could also inform how alkalinity enhancements interact with polar ecosystems facing rapid warming.

Opinion: Against The Arctic Island Laboratory

21 July 2025, Cody Alexander Skahan, grapevine.is

Iceland is frequently portrayed as a hotspot for carbon capture and storage partially because of the country’s “abundance” of cheap, renewable energy and geological makeup (formed millions of years ago) suitable for CO2 mineralisation to support direct air capture of carbon. Through his anthropological PhD research on the social and cultural dimensions of these projects, the author has observed that Iceland is also chosen for these projects because of its perceived social and political license for such projects. This is a problematic perception rooted in others treating Iceland as an isolated “island laboratory”.

Pollution Paradox: How Cleaning Up Smog Drives Ocean Warming

28 May 2024, Fred Pearce, e360.yale.edu

New research indicates that the decline in smog particles from China’s air cleanups caused the recent extreme heat waves in the Pacific. Scientists are grappling with the fact that reducing such pollution, while essential for public health, is also heating the atmosphere.

Some scientists say blocking the sun could slow climate change — just like on The Simpsons

12 September 2023, CBC, www.cbc.ca

Scientists say geoengineering, or doing things like intentionally increasing Earth’s reflectivity or blocking the sun, is a “really big deal” in slowing down climate change. Here are the ideas they are proposing.

Developing a National Strategy for Climate Engineering Research in Canada

02 November 2017, A. Neil Craik, www.cigionline.org

Climate engineering (CE) is increasingly becoming an area of broad public policy interest within international and domestic climate policy discussions. In addition to receiving greater attention within regulatory contexts, there is a gradual shift toward greater support for nationally supported research programs on CE technologies and assessments. Despite the increased salience of CE, the issue has been largely absent from the Canadian public policy agenda. This paper argues that a national strategy for CE research ought to be developed as part of Canada’s broader climate strategy. At the centre of this strategy must be a commitment to ensuring a high level of public trust in the underlying science and a policy process that is open and responsive to public views.
