New research uncovers potential benefits, consequences of ocean iron fertilization

Removal of excess carbon dioxide in the atmosphere, in addition to major reductions in ongoing emissions, is required to stave off the most severe consequences of climate change. Large-scale ocean iron fertilization is one of several strategies that could help remove carbon dioxide, but new research published this week in Global Change Biology by a Bigelow Laboratory for Ocean Sciences researcher and colleagues shows that it might also negatively affect marine ecosystems in far corners of the ocean.
