There will be a lot of noise around the world on Sept. 21st when people all over the globe - from New York to Guatemala to Dakar - join together in a Global Climate Wake Up Call. 
Organized by the amazing folks at Avaaz, Oxfam, Greenpeace and 350.org the Global Wake-Up Call , will see people from all walks of life get together in public places to sound the alarm and urge our political leaders to stand up and take bold action at the Copenhagen Climate Treaty Summit scheduled for December of this year.
These will be peaceful, spontaneous "flash mobs" in public places where people will sound the alarms on their mobile phones, flood their governments with phone calls urging climate action, and make a tremendous noise. The images, sounds, and videos will be stitched together overnight for presentation to world leaders at the United Nations the next day.
To say that the Copenhagen Summit is a key moment in our history would be the understatement of the century. At this meeting our government representatives will decide the path we will take for the next decade: Will we continue to allow the unabated burning of dirty fossil fuels like coal and oil? Or will go down a path that starts to reduce this over reliance on fossil fuels and begins to take full advantage of clean, healthy, cheap and unlimited power sources like the sun and the wind?
Actions like the Global Wake-Up Call are important because they give politicians the space they need to make the right decision. If they know that they have the support of their people, they will feel emboldened to be the leaders we need them to be in Copenhagen.
People are already stepping up big time, with over 350 events planned in 54 countries - there's probably one already in the works in your town. So tweet about it, Facebook it, blog about it, email your friends and ask them in turn to email the Global Wake Up Call along to their friends and most importantly show up. 
Here's an interactive map of all the events already planned  for September 21st. Wouldn't it be cool to see this entire map blotted out by actions all over the world?
