Editor's Notes
- Fossil fuel CO2 emissions decreased by 1.3% in 2009, with a total of 8.4±0.5 PgC emitted to the atmosphere (30.8 Pg of CO2; 1 Pg = 1 billion tons or 1000 x million tons). These emissions were second highest in human history, just below 2008 emissions, and 37% higher than in 1990 (Kyoto reference year). Coal is now the largest fossil-fuel source of CO2 emissions. About 92% of the growth in coal emissions for the period 2007-2009 resulted from increased coal use in China and India. CO2 emissions from fossil fuel and other industrial processes are calculated by the Carbon Dioxide Information Analysis Center of the US Oak Ridge National Laboratory. For the period 1958 to 2007 the calculations were based on United Nations Energy Statistics and cement data from the US Geological Survey, and for the years 2008 and 2009 the calculations were based on BP energy data. Uncertainty of the global fossil fuel CO2 emissions estimate is about ±6%. Uncertainty of emissions from individual countries can be several-fold bigger. The abrupt decline in fossil fuel emissions by 1.3% in 2009 is indisputably the result of the global financial crisis (GFC). A detectable lower-than-average growth of 2% in 2008 already signaled the beginning of the impact. The decline in 2009 was smaller than anticipated because: 1) the contraction of the Global World Product (GWP) was only -0.6%, as opposed to the forecasted -1.1%; and 2) the impact of the GFC was largely in developed economies which led more carbon-intense economies to take a larger share of the production of global wealth (with associated higher emissions). The long-term improvement of the carbon intensity of the economy (amount of carbon emissions to produce one dollar of wealth) is -1.7% y-1; the carbon intensity of the economy in 2009 improved only by -0.7% y-1. We estimate an emission growth of at least 3% in 2010 based on the forecast of +4.8% GWP growth rate of the International Monetary Fund, corrected for expected improvements in the carbon intensity of the global economy.
- Current emissions are tracking above the most intense fossil fuel emission scenario established by the IPCC Special Report on Emissions Scenarios-SRES (2000), A1FI (A1 Fossil Fuel intensive); and moving rapidly away from low stabilization scenarios, eg, 450 ppm. Scenarios trends are averages across all models available for each scenario class. Since this publication, global fossil fuel emissions have been revised and used in Canadell et al. 2007, PNAS. Red dots indicate the revised and updated numbers for 2005 and 2006 respectively. When the IPCC-SRES scenarios where published the AIFI was considered an outrageous scenario which was there as a top end, and for almost 10 years we have been happy to use the B1 as a middle of the rate scenario for what it is most likely to happen. We have studied impacts, risk assesment and we have even developed policies with this scenario.
- Here we see the typical saw-tooth pattern of temperature which marks the short interglacial (warm) periods followed por longer glacial periods. In every case, CO2 records and temperature records correlate. What will happen in our newly CO2-enriched climate, however, is anybody’s guess. Scientists have used computer models to show that temperatures will likely increase between 3 and 11 °F over the next 100 years. Following every peak in CO2, there is an immediate drop. This happened 10,000 years ago, but slowed once humans began agricultural activity. Now, the level of CO2 is skyrocketing and is expected to exceed 600 ppm por 2050!
