Airline Travel Revealed

I guess because I spend much of my time reading dry words, I love it when I come across a visual image that conveys a strong message. Back in a September post, The Emergence of a Global Brain, I highlighted the work of Sala whose software maps web links. Even more interesting, in my opinion, is the video presented below by  Aaron Koblin - an animated rendering of US air traffic data from the FAA, with the hubs and spokes of flight paths lit up like highways and cities seen from overhead at night. It gives a whole new perspective to global warming --- note transport accounts for 15% of all carbon emissions.
