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.
I actually think you can trace many many of these big systemic crises to being symptoms of the flawed idea that economic growth can go on indefinitely, exponentially, on a finite planet. That’s sort of my North Star. And then as a finance person, why do we think we need economic growth? Well, because the way our capital system works is that capital demands that growth.
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.
There are biologists who’ve spent their careers working on some species of beetle in the tropical rainforest, and they just love the rainforest in their bones And they feel that when they go testify in Congress to some committee, that they can’t just say, “I love it in my bones and you guys will love it too, if you share it with me.” They have to say, “Oh, we’ve done all this math and computed that there’s an ecosystem service here.” And I think that that has really impoverished our debate about environmental issues.
I think the obvious thing to do with one computer per planet is fix climate change before it destroys agriculture and leaves billions of people to starve. That seems like a fairly reasonable kind of an objective. You know, there are all kinds of little optimizations you could do with these things, but fundamentally the big unsolved challenges that humanity faces are climate change and resource scarcity.
