The world's oceans may be quietly amplifying climate change in ways scientists are only beginning to understand. In a new study published in Proceedings of the National Academy of Sciences, University of Rochester scientists—including Thomas Weber, an associate professor in the Department of Earth and Environmental Sciences, and graduate student Shengyu Wang and postdoctoral research associate Hairong Xu in Weber's lab—uncovered a key mechanism behind methane production in the open ocean. Their research indicates that this mechanism could intensify as the planet warms, providing an alarming feedback loop for global warming.
