Population change

Changes in the human population, including aging and urbanization, could significantly affect global emissions of carbon dioxide over the next 40 years, according to research results published this week. The research, results of which appear in a paper in the journal Proceedings of the National Academy of Sciences (PNAS), was conducted by scientists at the National Center for Atmospheric Research (NCAR), the International Institute for Applied Systems Analysis (IIASA) and the National Oceanographic and Atmospheric Administration (NOAA).

It was funded by the National Science Foundation (NSF), a European Young Investigator’s Award, and the Hewlett Foundation.

“By examining the relationship between population dynamics and greenhouse gas emissions, this groundbreaking research increases our understanding of how human behaviors, decisions and lifestyles will determine the path of future climate change,” says Sarah Ruth, program director in NSF’s Division of Atmospheric and Geospace Sciences, which funds NCAR.
