Table 2.14 (Errata). Lifetimes, radiative efficiencies and direct (except for CH4) GWPs relative to CO2. For ozone-depleting substances and their replacements, data are taken from IPCC/TEAP (2005) unless otherwise stated. See IPCC AR4 (Forster et al., 2007; Section 2.10.2 and Table 2.14) for details. A number of species were inadvertently omitted that should have been included in the list, and the complete table appears below. Information on the GWPs of these species were included in IPCC TAR (Ramaswamy et al., 2001;Tables 6.7 and 6.8). These species are now included in this Errata to Table 2.14 of IPCC AR4 (Forster et al., 2007), following established procedures and precedents. CO2 AGWP values from IPCC AR4 (Forster et al., 2007; Section 2.10.2), and estimates of the lifetimes and radiative efficiency of these species (based on TAR and updates from WMO (2002, Chapter 1)), are employed to obtain their GWPs. Estimates of GWPs from SARare also listed for reference. Minor typographical errors (unit, parenthesis, superscripts, and footnotes) have also been corrected in this Errata.

Notes:

a The CO2 response function used in this report is based on the revised version of the Bern Carbon cycle model used in Chapter 10 of this report (Bern2.5CC; Joos et al. 2001) using a background CO2 concentration value of 378 ppm. The decay of a pulse of CO2 with time t is given by

Where a0 = 0.217, a1 = 0.259, a2 = 0.338, a3 = 0.186, τ1 = 172.9 years, τ2 = 18.51 years, and τ3 = 1.186 years.

b The radiative efficiency of CO2 is calculated using the IPCC (1990) simplified expression as revised in the TAR, with an updated background concentration value of 378 ppm and a perturbation of +1 ppm (see Section 2.10.2).

c The perturbation lifetime for methane is 12 years as in the TAR (see also Section 7.4). The GWP for methane includes indirect effects from enhancements of ozone and stratospheric water vapour (see Section 2.10.3.1).

d Robson et al. (2006)

e Hurley et al. (2005)

f Shine et al. (2005c), updated by the revised AGWP for CO2. The assumed lifetime of 1,000 years is a lower limit.

Second Assessment Report (IPCC, 1996)

* Compound in SAR (Table 2.8) was erroneously listed as CH3Cl3.

errata 27 january

FAQ 2.1, Figure 1 (Errata). Revised figure showing atmospheric concentrations of important long-lived greenhouse gases over the last 2,000 years. Using the combined and simplified data from Chapters 6 and 2, the original figure displayed the CH4 curve incorrectly. The revised figure shows the same data correctly plotted. For further details please refer to the original figure caption.
