Emissions accelerating faster than economy

The US National Academy of Sciences have just produced a report which finds that global greenhouse gas emissions have since 2000 been growing more quickly than the global economy. This is faster than the worst predictions of the Inter-governmental Panel on Climate Change (IPCC).

Here is the summary text with graph:

"Carbon dioxide released to the atmosphere is the main culprit in human-induced global warming. Typically, developed countries are identified as the main source of CO2 as a result of the burning of fossil fuels and other industrialized processes. An analysis by Michael Raupach et al. shows that developing countries are quickly catching up in CO2 emissions. The authors studied regional trends in emissions, energy use, and population and economic growth to determine patterns that affect CO2 emission and, ultimately, global warming. The analysis showed that, since 2000, CO2 emissions worldwide have increased more rapidly than predicted because emissions and energy use are growing faster than the gross domestic product (GDP) of many countries. No countries are decreasing their percentage of reliance on fossil carbon as an energy source. In addition, developing countries show significantly increased recent rates of growth in emissions. Developing economies, together forming 80% of the world's population, accounted for 73% of the global growth in emissions in 2004. However, these economies accounted for only 41% of emissions themselves and only 23% of emissions since the start of the Industrial Revolution around 1800."
