Popular Science and Google Earth

I just read this from the Google Earth Blog, Popular Science's July issue is highlighting the use of Google Earth for aiding in visualizing the environment. There are 5 visualizations highlighted:

1. Volcano Tracker: This is the coolest, basically watch volcanic ash plumes.
2. Storm Trooper: Watch air flights going into storms
3. Emotion Map:3-D visualization of people's emotions in Greenwhich, England
4. Arctic Eye: Watch the Arctic Ice melt
5. Flight of the Bird Flu: Track the bird flu virus

My favorites are the Volcano Tracker and Arctic Eye, I had problems getting the Bird Flu tracking to work properly.
