"This Outlook provides a window into the future as we view it in 2013. While the world has made progress, much more effort is needed to avoid dangerous climate change and its potential damaging impacts. From this research effort, it is clear that the Copenhagen–Cancun pledges do not take us very far toward the energy transformation ultimately needed to avoid the risk of dangerous warming. Even if policy efforts in developed countries are successful in holding emissions constant, as other nations grow and industrialize their emissions will contribute to further increases in greenhouse gas concentrations and climate change."
