As a human-centered designer what is my role, what is our role, in this kind of bigger picture? If this is the dominant lens of society, what’s our contribution?
For this theoretical physicist here it seemed actually very simple. It’s a conservation law. If you take carbon out of the ground and you put it into the system it will stay there unless you take it back out. From a societal perspective, this is much much more complicated because as we fix it there will be winners and losers.
Solar geoengineering rests on a simple idea that it is technically possible to make the Earth a little more reflective so that it absorbs a little less sunlight, which would partly counteract some of the risks that come from accumulating carbon dioxide in the atmosphere. When I say technically possible, it appears that at least doing this in a crude way is actually easy, in the sense that it could be done with commercial off-the-shelf technologies now, and it could be done at a cost that is really trivial, sort of a part in a thousand or a part in ten thousand of global GDP.
