The NASA Earth Observatory site has an extensive archive of images and data that enable you to see the global distribution of many environmental parameters such as ozone, vegetation cover, forest fires, sea surface temperatures, and many others. You can select measurements from the dataset to make a Quicktime movie of how a parameter of interest changes from month to month or year to year.
