Co-head of environmental club is an IGSS student, Jesse hosted a 350 event after school on Friday with live music and students urging folks to call their representatives and senators to support Green legislation. This event kicks off a world-wide Saturday demonstrations Saturday to call for urgent action on climate change.
Saturday events were being coordinated by a group called 350.org, whose name refers to the parts per million of carbon dioxide it considers the safe upper limit for our atmosphere. More than 5,400 rallies and demonstrations were scheduled to take place around the world, all of them centered on the number 350.
CNN reports:
"The number of 350 ppm originally came from a NASA research team headed by American climate scientist James Hansen, which surveyed both real-time climate observations and emerging paleo-climatic data in January 2008, according to 350.org.
It concluded that atmosphere containing carbon dioxide above 350 ppm couldn't support life on earth as we know it".
