Google Earth tour showcase looking for information about hurricanes. Although I didn't find what I was looking for, I did find a nice tour of Canada's boreal forest. The tour, produced by the Pew Environment Group, takes you through the largest tract of intact boreal forest in the world. You can play the five minute tour as a video or stop and explore individual aspects of the tour in Google Earth. You can grab the file here (link downloads KML file).
Applications for Education
If you're teaching environmental science this tour could be a good resource for highlighting the importance of preserving the forest and the animals that call it home. It's also a good resource for highlighting the role of forests in climate change mitigation.
