Greg, cc list:
1. Thanks for alerting us on 1 July to the cloudiness-CDR-related
message found at the Russ George website
(http://russgeorge.net/2017/07/01/greatest-uncertainty-in-climate-change-models-is-diminishing-cloudiness/
<http://russgeorge.net/2017/07/01/greatest-uncertainty-in-climate-change-models-is-diminishing-cloudiness/>
). I hope others can chime in on the validity of the strong relationship
George asserts between phytoplankton and clouds. Is this as important as the
much discussed SRM option involving ships spraying salt particles to help form
clouds?
2. Your brief cite from Russ George refers to “a new paper” - which
(free and 9 pages) can be found at
http://onlinelibrary.wiley.com/doi/10.1002/2017EF000601/epdf
<http://onlinelibrary.wiley.com/doi/10.1002/2017EF000601/epdf>, entitled:
“Could geoengineering research help answer one of the biggest questions in
climate science?”
with first author Robert Wood. The “biggest question” is of course
related to cloud formation as stated in your quote below from Russ George.
3. I was amazed at the many messages at the George site that relate to
geoengineering and this cloud topic (and NOT to Russ George’s fame with OIF =
Ocean Iron Fertilization). Examples of cites that I found relating to this
cloud-plankton topic:
a.
https://www.atmos.washington.edu/~robwood/papers/geoengineering/Wood_Ackerman_CLIMATICCHANGE_2013.pdf
<https://www.atmos.washington.edu/~robwood/papers/geoengineering/Wood_Ackerman_CLIMATICCHANGE_2013.pdf>
(A predecessor to the above “biggest question” paper.
b.
https://academic.oup.com/bioscience/article/60/9/722/238034/Microalgae-The-Potential-for-Carbon-Capture
<https://academic.oup.com/bioscience/article/60/9/722/238034/Microalgae-The-Potential-for-Carbon-Capture>
A 2010 article by Sayre (recommended by Russ George):
c. https://www.thenakedscientists.com/articles/features/clouds-plankton
<https://www.thenakedscientists.com/articles/features/clouds-plankton> a short
free 2014 more non-technical contribution on the sulfur aspects.
d. James Lovelock in a later book ‘The Revenge of Gaia’ in 2006, refers to
his Anti-CLAW Hypothesis. CLAW comes from four last names - with L for
Lovelock. This shows that this is not a new topic. I hope some on the list
with a real background (I have none) can give other opinions on how seriously
we should take Mr. George’s views on plankton-clouds-climate (as opposed to
plankton and increased salmon production).
4. I suspect there could be a biochar side to this cloud aspect of
ocean biomass - and possibly even to phytoplankton. I suspect you have
probably given us this cite to agree with Ross George that the geo aspect
deserves study. I am not expecting you or anyone on this list to agree that
this should promote biochar. In fact, his emphasis on missing dust would say
that biochar’s emphasis on increased “green-ness” is evidence that biochar
should make less dust most likely. But I can also argue that biochar from
ocean biomass (placed on land, not in the ocean) could/might more than offset
the “dust-free” negative aspect of land-based biochar. Of course it opens the
possibility of a much larger supply than available from the 28 % of the earth’s
surface NOT ocean.
5. I also found the George message comparing the Sustainable
Development Goals (SDGs) #14 (oceans) and #15 (land) to be particularly
disturbing from a combined CDR/SRM perspective. Mr. George is particularly
upset about the UN system doing too little with #14 (oceans). I believe you
agree - and could be (?) the reason for your message below. This concern
about SDG #14 (brand new to me) is on much more than this relationship between
plankton and clouds - and could be worth considerable discussion by this list -
as CDR might look more possible with a bigger supply. So this is a very
separate reason for thanking you for your 1 July message below. I’ll send more
on only this in the AM.
