- US and European scientists have called off a controversial balloon test flight that was to take place in Sweden’s far north in June, part of a disputed solar geoengineering experiment to artificially cool the planet. The project has been dubbed SCoPEx, short for “Stratospheric Controlled Perturbation Experiment”.
- A team of Harvard scientists had been planning to launch a high-altitude balloon from the Esrange Space Station in the Swedish town of Kiruna, to test whether it could in future carry equipment to release solar radiation-reflecting particles into the Earth’s atmosphere.
- Mimicking the effect of volcanic eruptions, the project’s supporters say the technology should be studied to see if it could become a method of combatting global warming. But the project, like geoengineering itself, has raised concerns among both scientists and environmentalists who say the technology is dangerous and risky.
