[geo] RE: [The Enormous Risk of Atmospheric Hacking

[Douglas MacMartin]

Thanks Robert,

I’m certainly not an expert on cloud-aerosol interactions, other than what I 
read and who I talk with.

The two references you provide have, respectively, the following sentences:
“The model has been modified to have a fixed CDNC in the three regions of 
low-level marine stratocumulus; these regions are of the coasts of California, 
Peru and Namibia as shown in Figure  1 of Jones et al. 2009 [4]. ”

“… the three areas containing the most extensive concentrations of such 
clouds—off the West coasts of North and South America, and Africa [7,8,11]. 
These three areas (combined) cover approximately 5% of the total oceanic area 
and were used in most of the current computations outlined herein.”

Which are both consistent with my recollection of what I’ve seen elsewhere and 
read.  I have not read the details of either paper, but at least based on the 
introductions don’t see clouds over the Gulf Stream as being one of the areas 
where MCB is expected to be effective.  Am I missing something here?

(And I would repeat my caution in using GCMs to predict the efficacy of MCB, 
insofar as whatever they predict is based on whatever subgrid cell 
cloud-aerosol parameterization has been made in writing the model – and thus 
whatever uncertainties exist in that parameterization remain.  Using a GCM to 
say what might happen if MCB is effective is great, but using it to ask whether 
MCB is effective is a circular argument, as that effectiveness is simply coded 
in the assumptions in the model.)

Thanks Doug.  This discussion is relevant to geoengineering so copying to that 
group.

My conversations with Stephen Salter suggest brightening clouds over the Gulf 
Stream to cool the current would be an effective way to cool the Arctic.

Two papers which imply the Gulf Stream would be a good location for Marine 
Cloud Brightening are https://www.hindawi.com/journals/isrn/2012/142872/ and 
https://royalsocietypublishing.org/doi/pdf/10.1098/rsta.2014.0053

Subject: RE: [CDR] The Enormous Risk of Atmospheric Hacking

Well, unfortunately we don’t even know yet when/where/how much MCB works (and 
you should really really hope that it isn’t very effective, because that means 
that climate sensitivity is on the low end), so without understanding the right 
meteorology to influence, this isn’t ready to go deploy.  And over the gulf 
stream is not likely one of the regions where it is effective, if I recall 
right.   And if you do that at meaningful scale, I bet it would be 
controversial too, but of course no-one really knows.

And we don’t know how to pump water onto sea ice at any relevant scale, or the 
extent to which the newly formed ice is more saline vs adequate brine rejection 
(and if it’s particularly saline then it melts first, decreasing albedo earlier 
in the melt season).

These are all great things to research.  So is SAI.  Bottom line is, we do not 
have any options that we can simply go out and start doing tomorrow without a 
ton of research first.  (And the closest to being able to do that – which 
doesn’t mean it’s the best in any other respect – is high-latitude SAI.)  I 
think it’s a bit premature to start throwing out options.

(And once again removing the CDR google group from the addressees, since this 
doesn’t belong there.)

Subject: RE: [CDR] The Enormous Risk of Atmospheric Hacking

Planetary brightening is essential to cool the temperature.  My view is the 
best ways to brighten and cool the planet are Marine Cloud Brightening using 
sea salt in the air to cool the Gulf Stream flowing into the Arctic, and 
pumping ocean water onto the Arctic sea ice cap to freeze over winter
