At the weekly peace vigil in Peterborough NH, on October 24, 2009, I set up a little exhibition about the need to get the atmosphere down to 350 parts per million of carbon dioxide, as part of http://www.350.org 's International Day of Climate Action.
I posted it as a video at Youtube
The music is a shortened version of the song "Have a Global Warming Day" from the freely-reusable song archive "Ourmedia" at archive .org (http://www.archive.org/details/Have_A_Global_Warming_Day) . We wrote the numerals "350" using 350 pennies.
