A blog post from the Bing Education team mentions hat the National Geographic Global Action Atlas is available using this URL from Bing Maps. Although the atlas is aimed at students and teachers it will likely be of interest to others.
The Global Action Atlas spotlights hundreds of local, cause-related projects from around the world to a large audience of concerned citizens, giving individuals opportunities to take action by donating, volunteering, advocating, and sharing information. The Atlas enhances and extends the mission of the National Geographic Society –to inspire people to care about the planet– by turning inspiration into action.
You can find an overview here.
Finally, another interface (using Bing Maps) and some extra features are available by going to to www.actionatlas.org.
