ESRI has produced a map that displays carbon dioxide emissions from 1960 to 2008. The map is dynamic in that it allows the user to pick the year, or consecutive years, to display in addition to having the ability to "play" the map as an animated timeline. Another cool feature of the map is that it has two sets of symbology; the map displays countries' total emissions as a color and relative emissions are represented by dots. For more information, including how the map was made, visit ESRI's Map Story Profile.
