Post-SRES Projections
Further information: climate change scenario#Quantitative emissions projectionsAs part of the IPCC Fourth Assessment Report, the literature on emissions scenarios was assessed. Baseline emissions scenarios published since the SRES were found to be comparable in range to those in the SRES. IPCC (2007) noted that post-SRES scenarios had used lower values for some drivers for emissions, notably population projections. However, of the assessed studies that had incorporated new population projections, changes in other drivers, such as economic growth, resulted in little change in overall emission levels.

Famous quotes containing the word projections:
“Predictions of the future are never anything but projections of present automatic processes and procedures, that is, of occurrences that are likely to come to pass if men do not act and if nothing unexpected happens; every action, for better or worse, and every accident necessarily destroys the whole pattern in whose frame the prediction moves and where it finds its evidence.”
—Hannah Arendt (1906–1975)
