As we try to objectively study nature, we are often reminded of how natural forces affect us personally. Anthropogenic climate change confronts humanity with a challenge: How can we keep warm now as we try to prevent our world from overheating in the future?

Low-level stratiform clouds—which play an important climatic role because of their net cooling effect on the global climate—appear to dissipate as the ocean warms, thereby enhancing the warming (i.e., a positive feedback), according to a new study of the NE Pacific by researchers from the University of Miami and UC San Diego.
