New geoengineering idea: Researchers want to dry out the stratosphere to prevent global warming. Western Pacific cold point would be the ideal location for stratosphere drying.
Small particles, known as ice cores, would be released into high-altitude regions of the atmosphere that are very cold and supersaturated with water vapor. Some of the water vapor in the air then condenses into ice and falls down - excess water vapor is thus removed from stratosphere and this at least partially dehydrated. In the study, the research team shows that the approach would work - but only with a very small effect, as Schwarz emphasizes.
