Recommendation

While dozens of marine geoengineering projects have been proposed to tackle global warming, none has been deployed on the massive scale necessary to make a difference. The risk of catastrophic results is amplified by a lack of solid scientific data. Moving forward, researchers must build a solid, shared database, catalog drawbacks and benefits, develop a specific methodology, and work under vigilant policymaker oversight. This Nature article will remind readers that, while climate change is a critical issue, people must not make the situation worse by harming the oceans.

Summary

The Intergovernmental Panel on Climate Change (IPCC) believes the key to reversing global warming is “negative-emissions technologies.”

Some scientists propose encouraging massive growth of phytoplankton in the sea, which would absorb CO2 and then sink.

Another idea is to create seawater clouds that reflect sunlight; yet another suggests spraying the entire Pacific Ocean with a billion tonnes of filmy, chalk-like material. These projects would have to be deployed on a huge scale to have a meaningful effect.

Limited research has been done on marine geoengineering ideas aimed at affecting climate change.

Before countries and companies invest in any large-scale project, the...
