Today is “Young and Future Generations Day” here at the International Climate Negotiations in Copenhagen, and I'm here with my wife Wahleah and our two-year-old daughter Tohaana. Along with thousands of other young people, we're doing everything in our power to convince world leaders to commit to a fair, ambitious, and legally binding international agreement based on a target of 350 parts per million (ppm), which is the safe upper limit of carbon dioxide in the atmosphere.

Less than 400 miles away in Oslo, Norway, President Obama is accepting the Nobel Peace Prize “for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples.” If ever there was a time and place to live up to that honor, now, in Copenhagen is it.

It can if that number is 350. That's the safe upper limit of carbon dioxide in the atmosphere: 350 parts per million (ppm). It’s also the rallying cry of a creative campaign to raise awareness of the climate crisis and build grassroots support for the 2009 Climate Conference in Copenhagen. 350.org wants communities around the world to join together on October 24 for an International Day of Climate Action. You can join with your church, your school, or your friends and do something to visibly get the word out about 350. [See the latest video from 350.org]
