350.org is an international campaign dedicated to building a movement to unite the world around solutions to the climate crisis - the solutions that science and justice demand. ...
Our focus is on the number 350 - as in parts per million, the level scientists have identified as the safe upper limit for CO2 in our atmosphere. But 350 is more than a number - it's a symbol of where we need to head as a planet.
"As chairman of the Intergovernmental Panel on Climate Change (IPCC) I cannot take a position because we do not make recommendations," said Rajendra Pachauri when asked if he supported calls to keep atmospheric carbon dioxide concentrations below 350 parts per million (ppm).
"But as a human being I am fully supportive of that goal. What is happening, and what is likely to happen, convinces me that the world must be really ambitious and very determined at moving toward a 350 target," he told AFP in an interview.
