Human-caused greenhouse gas emissions are like a cat burglar. They’re invisible and move noiselessly. However, they’re prone to leaving fingerprints, and scientists, acting as detectives, have been looking for those fingerprints. The latest discovery, announced Monday in a paper in the Proceedings of the National Academy of Sciences, makes the case… Read More
