OMG your videos changed my life

I want to thank you very much for your scientific content. I piece done here on Global Dimming got me interested in the issue of global warming. This same video has inspired me to study atmospheric chemistry and currently I am working in a lab studying aerosols at the University of California San Diego, all because of that one BBC Horizons documentary. Your video aggregations are in good taste and change people's lives. Sincerely,
~John H.
