摘要：

Fossil fuel emissions of CO2 to the atmosphere appear to have leveled off in recent years; however, atmospheric CO2 concentrations continue to rise. Our simple analysis shows that peaks in the growth rates of human population and fossil fuel emissions have been observed, but the growth rate of atmospheric CO2 has reached record levels and shows no indication of peaking. Before atmospheric CO2 concentrations can be stabilized at safe levels, a peak in the CO2 growth rate must be achieved.
