Saturday, Oct. 24 may not have been a formal holiday, but according to 350.org, it was "the world's most widespread day of political action."
According to the organization's website, "350 is the most important number in the world -- it's what scientists say is the safe upper limit for carbon dioxide in the atmosphere."
Participants in 5,245 actions from 181 countries gathered to demonstrate their desire for strong action from political leaders in the United Nations December climate negotiations in Copenhagen, Denmark.
The day's immediate results included the delivery of photos from the event to the UN Secretary General. But event organizers will not cease their actions there. A core team will be distributing fact sheets, photos and scientific data to delegates meeting in Barcelona, Spain, for final talks before Copenhagen.
The organization has not released a plan of action for December, but their website promises to keep interested citizens posted.
