	Bill McKibben "Civilization is what grows up in the margins of leisure and security provided by a workable relationship with the natural world. That margin won't exist, at least not for long, as long as we remain on the wrong side of 350. That's the limit we face." Bill McKibben is a co-founder and global organizer of 350.org. He is an American environmentalist and writer who frequently writes about global warming, alternative energy, and the risks associated with human genetic engineering.

	Rajendra Pachauri "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." Rajendra Kumar Pachauri has served as the chair of the Intergovernmental Panel on Climate Change (IPCC) since 2002. Pachauri has been outspoken about climate change. He is now serving as the head of Yale's Climate and Energy Institute (YCEI).

	Dr. James Hansen "If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm." Dr. James Hansen heads the NASA Institute for Space Studies in New York City. Dr. Hansen is best known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue. Dr. Hansen was elected to the National Academy of Sciences in 1995 and he received the prestigious Heinz Environment Award for his research on global warming in 2001.
	Liz Thompson As a resident of a Small Island Developing State, I am acutely aware of the dangers of global warming. Some countries are closer to the frontlines of global warming than others, but we are all affected by this global problem, which requires from us a global response. Getting to 350 means saving our planet and ourselves from a disaster of our own creation. Ms. Thompson has become one of the recognized leaders on environmental issues of the Small Island Developing States. During her time as Minister of Energy and the Environment of Barbados, she enacted a range of progressive policies for sustainable development and environmental protection. She also became a key voice to raise awareness of global warming in Barbados - a country where the challenges of climate change and conservation are of particular relevance.

	Lester Brown “The 350.org campaign recognizes the importance of asking not what is politically feasible, but what is scientifically necessary to avoid catastrophic climate disruption. Cutting net carbon emissions 80% by 2020 with basic economic restructuring in time will be challenging, but how can we face the next generation if we do not try? Saving civilization is not a spectator sport—we are in this together.” Lester R. Brown, described as “one of the world’s most influential thinkers” by the Washington Post, is Founder and President of Earth Policy Institute, a non-profit environmental research organization. One of the world's most widely published authors, his books have appeared in some 40 languages. His most recent book is entitled Plan B 4.0: Mobilizing to Save Civilization.

George Monbiot is an English writer, known for his environmental and political activism. He writes a weekly column for The Guardian, and is the author of a number of books.
	Colin Beaven "A crisis, they say, is a terrible thing to waste. And there is more than one crisis. First, is the crisis in our climate, which must be solved in a matter of years. Second, is the crisis in our way of life. In the developed world, people suffer from anxiety and depression in epidemic proportions. In the developing world, over one billion people have no access to clean drinking water. We must do better. We have a chance to find an improved way of life, both for ourselves and for our planet. Let's take it." Colin Beavan (aka No Impact Man) is a writer, speaker, blogger, author and film subject. He is the director of the international not-for-profit the No Impact Project.
