Climate geoengineering: what are we talking about? How effective and what new risks? - an article by Laurent Bopp
Parution dans la presse
"Climate geoengineering" covers a range of techniques that aim to manipulate the climate on a large scale in order to avoid the risks of climate change. These techniques range from space parasols to limit the arrival of sunlight in the atmosphere, to fertilizing the oceans so that phytoplankton consume more CO₂, to restoring and conserving wetlands where carbon is preferentially stored.

In October 2025, the French Academy of Sciences published a report detailing what we know and what we still don't know about the potential benefits of these techniques and the new risks they bring.
Elsa Couderc, Science and Technology section editor, explores here with Laurent Bopp, climatologist and academician, the new climate risks these techniques could bring. The second part of these "crossed views" is an interview with Manuel Bellanger, who studies the development of marine geo-engineering techniques at Ifremer with an economist's eye.
