geoengineering is that it, is it inverses the problem that we have right now with global warming and getting emissions reduced, which is a collective action problem. Geoengineering
geoengineering is reallyintriguing and I like a lot of the ideas that you presented.
geoengineering because we want to know whether it works but absolutely geoengineering is something we should take into account for instance uh Marine
geoengineering in principle Marine Cloud whitening is a very feasible project it would take about 2,000 ships unmanned to go around mostly in the South Pacific
Solar geoengineering is the idea that humans could deliberately alter the reflectivity of the planet by some set of technical
solar geoengineering .
Solar geoengineering , literally darkening the skies, reduce the amount of sunlight that comes into the Earth.
of geoengineering --there's many ideas out there that I just, I mean, I can talk to one, I guess scientist might be too generous of a word, but a researcher who wanted to change
So imagine solar geoengineering in a world that was run by benevolent dictators--
sunlight to simulate solar geoengineering .
Then there's solar geoengineering , the subject of this talk.
And solar geoengineering might change both of them, but again in different ways.
And it started solar geoengineering at the beginning.
And solar geoengineering directly goes after those.
either to ban solar geoengineering or to implement it is my guess.
And solar geoengineering may sort of reduce the coefficient, meaning that there's less risk for a given amount of accumulated carbon.
Maybe the geoengineering will fix things.
out uh big GE geoengineering projects it's futurism but there is a
forecast and geoengineering um that'll probably do to
connected to geoengineering and bioengineering,
things like geoengineering uh with things like radically redesigned agriculture uh radically redesigned
One is kind of platonic geoengineering .
So we can choose how much solar geoengineering there is.
field like climate change forecast like geoengineering it exerts a terrible
is green and I fear that geoengineering may well be necessary.
And then as people start looking at geoengineering the realization is that it is shockingly cheap.
in any possible need to use geoengineering to buy some time, frankly, because of major essentially
I'm going to really talk about solar geoengineering in two really different ways.
And we can talk a little bit about what solar geoengineering might look like in that world.
There's multi-model comparisons from these 12 geoengineering model intercomparison project models.
that contradicts any of these conclusions-- if you assume that solar geoengineering is implemented in this even-handed way I'm talking about.
And then my view is that if we use solar geoengineering , which I don't think we know whether we should or not yet,
of reduced damage and policy cost for solar geoengineering .
It might be possible to do some versions of solar geoengineering that target particular areas, like monsoons.
There are people who are looking at things like solar geoengineering , and seeding the clouds to keep temperatures down, or finding ways to suck carbon out
Basically all of them get flipped when it comes to geoengineering .
Human modification, geoengineering .
It's about a future where a lot of the geoengineering and biological engineering ideas I've been discussing today have actually come to pass.
that it's important to first make clear what geoengineering is, since most people have never heard of it. And geoengineering is--I would argue-- going to be something, it's
And geoengineering is one thing that we might do that could help mitigate some of the risk to the rest of us. But it's clear that if we do any kind of geoengineering ,
of people talk about when they talk about geoengineering technological hubris. And I think the degree that this discussion about geoengineering
these risks that everybody sees to pursue some sort of geoengineering ?
bullet, some act of geoengineering , right?
of the planet at planetary scale with things like geoengineering uh with things like radically redesigned
taking hold of the planet at planetary scale with things like geoengineering uh with things like radically redesigned
Because another chapter I look at is geoengineering and more techno or ambitious projects and ways to get carbon out or to lower
And I think if there's a single reason to take solar geoengineering seriously, it's not this paper that I happen to be the author of, but this set of papers
We really don't know very well about what the downsides of solar geoengineering are, and we need a simple, a parsimonious way
can boil down all of the question about how the climate responds to solar geoengineering to one number, which is really just this angle.
So this gives you some sense of what some famous people have said about solar geoengineering .
