Even though Climate Change is one of the main reasons for starting Build-It-Solar, I don't say much about it because talking about it seems to turn a lot of people off, and it seems more effective just to provide a lot of projects that both help on the Climate Change front and save money.
But, I thought that this video by Jim Hansen was exceptional in that it gives a simple and sensible statement of the Climate Change problem, AND it proposes a solution that might be acceptable to a much wider audience.
Have a look -- its only 17 minutes: http://www.ted.com/talks/james_hansen_why_i_must_speak_out_about_climate_change.html
If you want to leave a comment on the video, that's great, but comments that are not constructive and thoughtful will be removed.
