Russell,
I've been thinking further about testing the 'brightwater' idea.

I'm interested to know whether the salinity of the water is lik
Has anyone considered another attribute of pumice - that chemically it
surely includes a lot of Mg2SiO4 - which absorbs CO2 as it weathers to
bicarbonate? As such it will counter AGW by drawing down CO2, and will
counter ocean acidification by adding alkalinity to the ocean. It will
also add silici

I note from previous discussion of chemical weathering geoengineering
that the available surface area for weathering deposits was a critical
limitation. It would seem that, if residency times on the ocean
surface were significant, then wave-grinding could potentially address

Hello Andrew,
I hope you dont mind my checking with you as to whether you
kindly sent out to Google-group members the pdf I sent to you of our
Phil Trans Roy Soc MCB paper. I feel sure that you did, but I've had
no reaction and I dont seem to have recd a copy.

Hi all,
Our paper looking at precipitation pattern changes in CO2 ramp-up/ramp-down
experiments, where CO2 concentrations are smoothly increased then decreased
along the same path in a GCM, is out now online first in Climate Dynamics;

*Thus, an obvious path to avoiding sky whitening is to greatly limit or
avoid entirely the intentional introduction of sulfate particles into the
stratosphere.*
I agree with the avoiding part of this sentence. I live in Maine where the
sky really is blue and would hate to see skies here and aroun
