Climate changes from millions of years ago are recorded at daily rate in ancient sea shells, new research shows. A huge X-ray microscope has revealed growth bands in plankton shells that show how shell chemistry records the sea temperature. The results could allow scientists to chart short timescale changes in ocean temperatures hundreds of millions of years ago. Plankton shells show features like tree rings, recording historical climate. [Source: EurekaAlert!]
