350.org international day of action

On October 24, the International Day of Climate Action will cover almost every country on earth, the most widespread day of environmental action in the planet’s history with rallies, stunts and community actions all aiming to highlight the number 350. 350 parts per million is the safe level of C02 in the atmosphere identified by scientists beyond which humans face disaster. There are already over 140 350.org actions planned for Australia. Join one or start your own to show we don’t want Australia to continue to be a climate criminal and for Austalia to support real and urgent action at Copenhagen in December.

There will be big rallies in big cities, and incredible creative actions across the globe: mountain climbers on our highest peaks with banners, underwater demonstrations in island nations threatened by sea level rise, churches and mosques and synagogues and ashrams engaged in symbolic action, star athletes organizing mass bike rides—and hundreds upon hundreds of community events to raise awareness of the need for urgent action.

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. Two years ago, after leading climatologists observed rapid ice melt in the Arctic and other frightening signs of climate change, they issued a series of studies showing that the planet faced both human and natural disaster if atmospheric concentrations of CO2 remained above 350 parts per million.

Every event will highlight the number 350—and people will gather at some point for a big group photo depicting that all important message. At 350.org, we'll assemble all the photos for a gigantic, global, visual petition.
