The effect on global -
mean temperature of assuming a large value for indirect aerosol forcing (viz. − 1.8 W / m2 in 2005, the 95th percentile value according to the IPCC AR4) compared with temperatures for the
central indirect forcing
estimate (− 0.7 W / m2) and a less extreme maximum of − 1.1 W / m2.

mean values.

central estimate for a parameter like climate sensitivity with a highly skewed distribution.
Since no such effect has been observed or inferred in more than half a billion years of climate, since the concentration of CO2 in the Cambrian atmosphere approached 20 times today's concentration, with an inferred
mean global surface temperature no more than 7 ° K higher than today's (Figure 7), and since a feedback - induced runaway greenhouse effect would occur even in today's climate where b > = 3.2 W m — 2 K — 1 but has not occurred, the IPCC's high - end
estimates of the magnitude of individual temperature feedbacks are very likely to be excessive, implying that its
central estimates are also likely to be excessive.
