Can We Beat Climate Change by Geoengineering the Oceans?

30.06.22 | Cuca Margoux

Chemically altering the seas through iron fertilisation or alkalinity enhancement could be our best hope to suck vast amounts of carbon out of the atmosphere – but questions remain on whether it is worth the risk.

A SPRINKLING of iron ore “glued” onto rice husks using goo from plants hardly sounds like a recipe for saving the planet. Not to mention the fact that the mixture is designed to mimic whale faeces.

And yet if a team of researchers backed by a former chief scientific adviser to the UK government crack this, it could be coming to an ocean near you soon. Theirs is just one of several projects across the world, small in scale but big in vision, looking at a new way to stave off the worst effects of climate change: engineering the oceans.
