Science educators at the University of Colorado and the National Geophysical Data Center in Boulder have designed an online tool that lets users study climate change and variability on different time scales–from daily fluctuations to cyclic changes with periods that span 100,000 years. Focusing on climatic processes and specific climate events, each time-scale category has its own list of resources and links to additional information.
