I understand it's thought that SAI diffracted light could increase some
terrestrial growth because the light penetrates deeper into the canopy and
possibly engages chlorophyll on leaf undersides? I infer that'd have an
opposite effect on ocean primary production, but I can't find any studies about
this. I would think that light hitting at a shallow angle would reflect more
and refract less, decreasing the intensity, making for a more shallow path and
possibly the raising depth of the euphotic zone? The ocean is important in
carbon drawdown; and acidification, deoxygenation, stratification, and other
stressors take a toll on productivity. Less solar energy can't be helpful.
This is not my area of expertise, I'm a chemist, but it seems like no one is
worried about this... should I not be either? Thanks

ABSTRACTIn recent work, Joshua Horton and David Keith argue on distributive and
consequentialist grounds that research into solar radiation management (SRM)
geoengineering is justified because the resulting knowledge has the potential
to benefit everyone, particularly the ‘global poor.’ I argue that this view
overlooks procedural and recognitional justice, and thus relegates to the
background questions of how SRM research should be governed. In response to
Horton and Keith, I argue for a multidimensional approach to geoengineering
justice, which entails that questions of how to govern SRM research should be
addressed from the very outset – that is, now.

Tillerson, speaking on climate change at the Council on Foreign Relations, CEO
speakers series, 27 June 2012
‘Does geoengineering raise any ethical issues not already considered by
historical figures such as Aristotle, Hume, Kant, and so on? Isn’t the ethics
of making decisions that affect others not involved in making the decisions a
problem as old as humanity? I just don’t understand how there is anything new
here for philosophy…’ -Stanford scientist Ken Caldeira, Geoengineering Google
group, April 2012
‘Our government’s first duty is to its people, to our citizens – to serve their
needs, to ensure their safety, to preserve their rights, and to defend their
values. As President of the United States, I will always put America first,
just like you, as the leaders of your countries will always, and should always,
put your countries first.’ -Donald Trump, Speech to the United Nations General
Assembly, September 19, 2017
