Kind of left me hanging on page 72 though...
The group’s report looks in detail at the most promising technologies and policies for holding the gases at 445 ppm. It emphasizes the importance of improving energy efficiency in buildings and vehicles, shifting to renewable energy sources and saving forests as "carbon sinks." Policies include setting a target for global emissions, emissions trading schemes, caps, taxes and incentives.
But the IPCC scientists made their assessment before a study published online this past April in the Proceedings of the National Academy of Sciences USA reported that worldwide carbon dioxide emissions between 2000 and 2004 increased at three times the rate of the 1990s—from 1.1 to 3.2 percent a year. In other words, the actual global emissions since 2000 grew faster than those projected in the highest of the scenarios developed by the IPCC. That research indicates that the situation is more dire than even the bleak IPCC assessment forecasts...
