A SECRET CLIMATE EXPERIMENT IN ALAMEDA

Summary from the TLDR newsletter

A group of scientists launched a stream of microscopic salt particles off the deck of a decommissioned aircraft carrier last Tuesday in Alameda, California, as part of an experiment to limit global warming by increasing cloud cover to reflect sunlight away from Earth. Very few people knew about the project beforehand as geoengineering projects are controversial and the team was concerned that critics would try to stop them. The experiment will run through the end of May, and visitors are able to view the experiment.
