Harvard researchers have ceased a long-running effort to conduct a small geoengineering experiment in the stratosphere, following repeated delays and public criticism.
In a university statement released on March 18, Frank Keutsch, the principal investigator on the project, said he is “no longer pursuing the experiment.”
The basic concept behind solar geoengineering is that the world might be able to counteract global warming by spraying tiny particles in the atmosphere that could scatter sunlight.
