| Russell, to answer your question about the effect of temperature on the ocean carbon sink, attached is a “Spherical Cow” calculation for you. (It is actually a bit tougher than Spherical, hence in my Cylindrical Cow book; the attached corrects some typos in the book).
Also could you please explain the relevance of your observation about the aftermath of the Treaty of Versaille to the actual issue that was raised about the scale of the mobilization of the US economy that hugely helped win WWII?

Description: MS-Word document
John Harte Professor of Ecosystem Sciences ERG/ESPM 310 Barrows Hall University of California Berkeley, CA 94720 USA [email protected]
First let me congratulate you --the 2011 Climatic Change paper you kindly cite:
called for just such for model intercomparisons as you present:
"To determine the priority appropriate for study and potential deployment of hydrosols, a comparison is needed of advantages and disadvantages with respect to other approaches, such as stratospheric aerosol deployment, augmentation of cloud cover , and direct steps to reduce or reverse increases in the CO2 concentration .
However, I must point out that while your results are presented as
" a "unique Geoengineering Model Intercomparison Project Testbed experiment to investigate the benefits and risks of a scheme that would brighten certain oceanic regions. The National Center for Atmospheric Research CESM CAM4-Chem global climate model was modified to simulate a scheme in which the albedo of the ocean surface is increased over the subtropical ocean.... "
"Unique" means singular, and previous NCAR model simulations have examined the climate impact of air bubble modulation of surface water albedo, witness the 2011 paper you cite:
"To calculate the potential effects of microbubble injection, the CAM 3.1 global
circulation model developed at the National Center for Atmospheric Research
(University Consortium on Atmospheric Research 2008) has been used to simulate
the climate’s response to an increase in global ocean albedo. Baseline simulations
were conducted the CO2 concentration at preindustrial (280 ppmv), current
(390 ppmv), and double current (780 ppmv) levels. Using the doubled CO2 case
(780 ppmv) as the control, hydrosol simulations were conducted to examine the
counter-balancing effects of increasing ocean albedo by 0.01 and 0.05 above its
present average value"
You also note " A cooler ocean would increase the net carbon sink."
Can you please quantify this? Dan Schrag has told me carbonate buffering in sea water would minimize the carbon sequestration impact of lowering SST with microbubbles.
