The authors say that this novel approach captures CO2 from the atmosphere up to three times more efficiently than current methods.

The warming gas can be transformed into bicarbonate of soda and stored safely and cheaply in seawater.

The new method could speed up the deployment of carbon removal technology, experts say.

While the world has struggled to limit and reduce emissions of carbon dioxide in recent decades, several companies have instead focussed on developing technology to remove CO2 from the atmosphere.
