New paper: "Solar Geoengineering: History, Methods, Governance, Prospects" by @parson_ted & me in Annual Reviews.

I am particularly proud of this paper. This thread provides some highlights:
1/8

@UChicago The next director will inherit substantial momentum: 3 faculty hires toward a mandate of 10, 30 research projects, 20+ postdocs and fellows, $36M+ raised, and a chance to shape one of the most consequential fields in climate science and policy.

Excited to announce that we are searching for the next Faculty Director of @UChicago’s Climate Systems Engineering initiative (CSEi). I’m handing over the role but not retiring; I’ll keep teaching and researching. Know a candidate? Details: https://t.co/afxQ5pknIQ

[David Keith @DKeithClimate]

@UChicago I started working on geoengineering around 1989. One of the joys of helping this field evolve has been seeing a trickle of new faces turn into a torrent. Our plan was a ~5-year term. Launching a search now gives us the long runway this kind of recruitment needs.

@globeandmail Canada should use its deep nuclear power expertise to build 21st-century reactors. We have a good start with the first small modular reactor under construction in the G7 and ownership of @westinghouse's civilian reactor technology.

[David Keith @DKeithClimate]

I applaud Canada's recommitment to nuclear power. Now the government should abandon CANDU – Canada’s home-grown reactor technology. See my op-ed in @globeandmail: https://t.co/ned4brlBKV

[David Keith @DKeithClimate]

@globeandmail I'm proud of the clever design choices that allowed Canada to build its own indigenous reactor technology. But CANDU is the wrong answer today because it's nonstandard, has inherent safety challenges, and is proliferation risk.

[David Keith @DKeithClimate]

It's become commonplace among climate advocates to dismiss Nordhaus's DICE model or to claim it grossly understates climate damages.

For my part, I've been impressed by how DICE was adjusted and updated.

We've lost a thoughtful and gentle scholar.

[Zeke Hausfather @hausfath]

With William Nordhaus' recent passing the field of climate economics has lost one of its giants.

Nordhaus published in 1977 what was at the time a rather bold projection: the the world would warm by 1.2C by the year 2026. In reality it warmed by 1.1C.

I voted in 94 dimensions, WTF?!

Here are some observations on the U.S. voting mechanics compared to Canada. (Obviously, all this is much less important than the big question of checking the ludicrous American president, but it should be cleaned up).

[David Keith @DKeithClimate]

2. Weak privacy. People milled around voting booths without curtains. Worse, you had to feed your big paper ballot into a machine with an attendant beside it, and others nearby. Given the ubiquity of little cameras (now with AI), it would not be hard to monitor people's votes.

@geoengineering1 @doubledaybooks TBD. Publisher has the rights.

[David Keith @DKeithClimate]

Proud to announce my next book "Remaking Eden: The Science of Reversing Climate Change" will be published by @doubledaybooks in 2028. Writing it forced me to think more clearly than ever about the awkward politics of climate engineering. Can't wait to share it.

[David Keith @DKeithClimate]

I remain excited by the breadth of interest in climate engineering among @UChicago faculty and the diversity of research ideas.

My colleague Dan Fabrycky has found new orbits for space dust that could shade Earth. Here he is in the latest CSEi Research Spotlight video: https://t.co/XKKGaew2nB

Some thoughts, if you care about Alberta's place in Canada...

@acoyne's column nailed it: https://t.co/leMm0cExgW

Some choice quotes:

[David Keith @DKeithClimate]

@acoyne "Just 8% favoured secession itself, even in principle, based on the gauzy fantasies – an effortless break followed by eternal prosperity – spun by the secessionist campaign...After months of debate, fewer Albertans support secession than believe the moon landings were faked."

[David Keith @DKeithClimate]

@CSPopoff Maybe. There's lots to do. Protecting the test ban treaty, oposing golden dome....and much more.

My wife, Kirsten Anderson, and I are finally getting organized about giving away the money we made when Carbon Engineering was sold. Our platform is Luminen, Finnish for snow-covered, after our love of the cold outdoors. Learn more: https://t.co/xGrjZEpTkl
