It is estimated that Mount Pinatubo sent 20 million tons of sulphur dioxide (SO2) aloft (see: <a HREF="http://www.pbs.org/wgbh/nova/sun/dimm-nf.html" rel="nofollow">link</A> ; see also NASA on global dimming: <a HREF="http://www.nasa.gov/centers/goddard/news/topstory/2007/aerosol_dimming.html" rel="nofollow">link</A> .

I can't wait for the longer review of the book! But there was something in the text that grabbed my attention: <blockquote>Cooling the Earth can be further achieved by sulphate aerosols, soil carbon sequestration by adding pyrolytically charred biomass and massive re-forestation.</blockquote>I know sulphate aerosols has been discussed numerous times by now. But I am still wondering what kind of effect this actually will have. As you probably already know the lifetime of aerosols is quite short. How much sulphate aerosols is needed to have a strong effect, and not just a local effect? A great piece of text, yet again, Gideon. I can’t wait for the longer review of the book!
