Target Atmospheric CO2: Where Should Humanity Aim? [1]
This paper outlines the implications of climate change with regards to paleoclimatology and CO2 levels in the atmosphere. Climate sensitivities and forcing are calculated in the context of historical climate change, and the relationships of current climate trends to tipping points are discussed. Finally, acceptable levels of atmospheric CO2 are established with a limit of 450 ppm and a long-term target below 350 ppm.
