Science Suggests 350 as Target for CO2
April 14th, 2009 byTarget Atmospheric CO2
Where Should Humanity Aim?
“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.”
The International Panel on Climate Change (IPCC) and Al Gore have been telling us that rising levels of atmospheric CO2 is at the heart of the global warming problem. Now, a group of leading climatologists and scientists are pointing us toward the key to the solution: do what is needed to get atmospheric CO2 concentrations back down to 350 parts per million (ppm) or less.
This simple, yet powerful conclusion is taken from a 2008 paper by ten scientists from the United States, the United Kingdom and France. The authors include James Hansen, top climatologist at the NASA Goddard Institute for Space Studies in New York.
The conclusions in this paper stand out because they provide humanity with a science-based distinction between safe CO2 levels and dangerous CO2 levels. clarity what must be achieved to preserve the Earth’s capacity to function and support life as it has for many thousands of years. For anyone seeking to understand what must be done to end global warming and normalize climate change, this scientific paper is arguably one of the best places to start.
The paper is featured at SafeCO2.org to make the paper itself easier to find. Also, background information and key sections are highlighted so that non-scientists can extract the many conclusions that are contained in this technical, scientific paper.

Thank for putting this up. 350 is a target we have long missed. Getting near 350 is going to really take some concerted effort. No clean coal hoax is going to do it. At the end of the day clean coal will cost far more per KW delivered, in fact it could double the average cost per KW of electricity delivered. I do co2 atomospheric measuring equipment and I now use 400+ as a outdoor standard,and 800 as a resonably ventilated indoor. People are taking CO2 measurments on faith, when you make your own mesurement there’s no denying the facts.
