Please note that the original “wedges” article published in 2004 showed seven wedges in the stabilization triangle. Seven was, at the time, to the nearest integer, the global CO2 emissions rate from fossil fuels and cement, in units of billions of tons of carbon per year. Note, tons of carbon, not tons of carbon dioxide. Since 2004, this rate has grown steadily and now (2022) probably corresponds to ten wedges (10 GtC/yr, which is equivalent to 37 GtCO2/yr).
