Myhrvold and Wood, and by extension L&D, are proposing that we pumps megatons of SO2 into the stratosphere in order to cool the Earth, but the only way to make this plan politically viable would be to rely on projections from climate models —
the very same climate models that have been dismissed by the authors and the IV crowd.
Aren't
these the very same climate models that the IPCC has bet its... I mean, our houses on?
also use a downscaling approach applied to more - or-less
the very same climate model simulations.

A 2005 Intergovernmental Panel on
Climate Change report on carbon capture and storage, which guided Shaffer's
modeling, said it was «
very likely» that 99 percent of stored C02 would stay in place over the first 100 years and «likely» that the
same percentage would stay in place over 1,000 years.
«The result is not a surprise, but if you look at the global
climate models that have been used to analyze what the planet looked like 20,000 years ago — the
same models used to predict global warming in the future — they are doing, on average, a
very good job reproducing how cold it was in Antarctica,» said first author Kurt Cuffey, a glaciologist at the University of California, Berkeley, and professor of geography and of earth and planetary sciences.
The
model is the first to consider how the effects of
climate change impacts — and the policies designed to address them — will produce
very unequal outcomes between the rich and poor in the
same country.
Recently I have been looking at the
climate models collected in the CMIP3 archive which have been analysed and assessed in IPCC and it is
very interesting to see how the forced changes — i.e. the changes driven the external factors such as greenhouse gases, tropospheric aerosols, solar forcing and stratospheric volcanic aerosols drive the forced response in the
models (which you can see by averaging out several simulations of the
same model with the
same forcing)-- differ from the internal variability, such as associated with variations of the North Atlantic and the ENSO etc, which you can see by looking at individual realisations of a particular
model and how it differs from the ensemble mean.
He cites he had many of the
same problems that
Climate Scientists face today (lack of data, couldn't
model very well, etc..)
