It's also incorrect: 36000 * 2500 m^3 * 2 kg/m^3 is only 180 Gg. I think they used the density of dry ice (1500kg/m^3) by mistake. Measuring in teragrams is al

It's also incorrect: 36000 * 2500 m^3 * 2 kg/m^3 is only 180 Gg. I think they used the density of dry ice (1500kg/m^3) by mistake. Measuring in teragrams is also not very useful, as virtually all climate-related stats are reported in in tonnes of CO2 equivalent ("tCO2e", which ain't exactly proper SI unit formatting but is still widely used). 140 Tg of CO2e = 140 MtCO2e. World CO2e emissions are ~40 Gt/year, for reference.
