Climate ocean tech fix ‘can work’, research suggests
Fertilising the oceans with iron to combat climate change can lock carbon away for centuries, research suggests.
Tiny marine plants induced to grow by the iron sink to the ocean floor taking carbon with them, a German-led team reports in Nature journal.
Iron fertilisation is one of the oldest ideas for a climate “technical fix”.
But much more research is needed before the approach could be put to use, the scientists say, and cutting emissions should be the priority.
