Summary

Shows in graphic form the projected increase in <a href="https://en.wikipedia.org/wiki/carbon_dioxide_in_Earth%27s_atmosphere" class="extiw" title="en:carbon dioxide in Earth's atmosphere">carbon dioxide</a> (CO2) emissions from <a href="https://en.wikipedia.org/wiki/fossil_fuels" class="extiw" title="en:fossil fuels">fossil fuels</a> in five of the <a href="https://en.wikipedia.org/wiki/en:Special_Report_on_Emissions_Scenarios" class="extiw" title="w:en:Special Report on Emissions Scenarios">emissions scenarios</a> used by the <a href="https://en.wikipedia.org/wiki/Intergovernmental_Panel_on_Climate_Change" class="extiw" title="en:Intergovernmental Panel on Climate Change">Intergovernmental Panel on Climate Change</a> (IPCC), compared to the <a href="https://en.wikipedia.org/wiki/International_Energy_Agency" class="extiw" title="en:International Energy Agency">International Energy Agency</a>'s (IEA's) actual observational CO2 emissions data from <a href="https://en.wikipedia.org/wiki/fossil_fuel" class="extiw" title="en:fossil fuel">fossil fuel</a> consumption.

The graph shows five of the illustrative "marker" scenarios from the IPCC's <a href="https://en.wikipedia.org/wiki/Special_Report_on_Emissions_Scenarios" class="extiw" title="en:Special Report on Emissions Scenarios">Special Report on Emissions Scenarios</a> (SRES). The SRES report contains a total of 40 <a href="https://en.wikipedia.org/wiki/greenhouse_gas" class="extiw" title="en:greenhouse gas">greenhouse gas</a> emissions scenarios. Between the years 2000-2009, growth in CO2 emissions from fossil fuel burning was, on average, 3% per year, which exceeds the growth estimated by 35 of the 40 SRES scenarios (34 if the trend is computed with end points instead of a <a href="https://en.wikipedia.org/wiki/linear_fit" class="extiw" title="en:linear fit">linear fit</a>) (Le Quéré et al., 2010).
