In project syndicate's article by Bjørn Lomborg we find: «For sea - level rise, the IPCC now includes
modeling of glacier
responses of 3 - 20 centimeters, leading to a higher total estimate of 40 - 62 cm by century's end — much lower than the
exaggerated and scary figure of 1 - 2 meters of sea - level rise that many environmental activists, and even some media outlets, bandy about.»
The average of the two scaling factors implies that the CMIP5
models analysed on average
exaggerate the
response to aerosols, ozone and other non-greenhouse gas anthropogenic forcings by almost 70 %.
