My new book Climate Uncertainty and Risk has arrived! Early reviews: “Judith A. Curry leverages her background in climate science, weather forecasting, and devising risk management strategies to present the climate policy debate we have never had. Her balanced, evidence-based, and multifaceted discussion leaves the reader ‘better informed as to the uncertainties and the various values in play’ in designing climate policy.”―Peter Hartley “Judith A. Curry is one of the world’s leading scholars of climate change and a deep thinker about how science copes with uncertainty. In this refreshing and comprehensive book, she shows with meticulous care and great clarity that exaggerated claims about climate change made for political purposes are wide of the mark. Instead, she shows the way to a rational and practical discussion of this polarized topic.”―Matt Ridley “With climate models running too hot by a factor of 2 for 30 years, with everything that used to be called a weather event now a portent of climate change, and with billions being invested against this as opposed to other more pressing world needs, Judith A. Curry provides us with a much-needed and convincing rethink.”―Michael Kelly amazon.com/s?k=judith+curry+…

Well this is how to approach the data center situation. Will be interesting to see how this plays out locally against all the brainwashing on this topic
SpaceX did something on November 4 that most companies building AI infrastructure never bother to do. It sent its own people into an elementary school auditorium in Cochise, Arizona, put the numbers on the table and took questions from a packed room. Riley Trettel, who leads energy and supercomputer development at SpaceX, said it plainly: "SpaceX is the owner, and with approval, will be the builder and the owner of the project long term." Then he laid out what the county gets. Up to 40% off residential power bills for Sulphur Springs co-op members for the life of the project. $3.6 billion in new power lines paid by SpaceX and handed to the co-op, which takes on no debt. $30 to $100 million a year in new property tax, with a 20% cut in everyone else's county property taxes. Enough one-time sales tax to pay off the county jail bond. Dry cooling, so the whole campus uses about as much water as 20 to 30 homes. No gas turbines on site. Up to $50 billion invested and about 1,000 permanent jobs. On the latest All-In, one of the hosts brought up the video of that night. "These two very bright, earnest people from SpaceX trying to explain how they're going to reduce electricity cost by 40%. They don't use water. They'll reduce property taxes by 20%." About Riley and Katie: "Good SpaceX employees. They should be proud of how they conducted themselves." They were shouted over from the first slide. Months of headlines about data centers draining aquifers and spiking bills did that work before anyone walked in. Some residents stayed after the presentation to tell SpaceX they want it there. The county's planning and zoning hearing is December 9.

bayes nails the AI meta issues
We need to stop using generic terminology. AI is not a monolith. There are critical things we need to do with AI for economic prosperity, there are things we may have to do for reasons of national competition, there are things we will at some point need to do carefully for the sake of charting and taming the computational universe, and there are things we should totally avoid doing at this stage of history, and maybe ever, if at all possible. If we can’t be precise about these issues because we’re saying vague things like “using coding agents to make AI progress should be illegal”, then we risk failing altogether. Each of the goals above depends on achieving the others. If we can’t prosper we can’t lead the world into the future. Everyone needs to internalize this. Democrats cannot subjugate themselves to antigrowth. Republicans cannot subjugate themselves to technocapital. Both roads lead to despair.

Yes!
If you’re looking for a worthwhile way to spend your weekend, read Evald Ilyenkov’s fiery masterpiece, Our Schools Must Teach How to Think! He demolishes the fantasy that overloading a child’s brain with facts about different subjects teaches them how to think. As Heraclitus++

Another analysis, by @RogerPielkeJr, illustrating the fundamental issues with using panel econometrics to draw broad conclusions about macroeconomic damages from climate change (and by extension legal liability). Roger's analysis illustrates several of the themes (e.g., influential points, understated and irreducible model uncertainty) raised by @FinbarCurtin's and my working paper from few months ago, in different papers from the ones we examined. This time, Roger argues there are sensitivities and possible data errors in famous Science and Nature papers used to support ongoing climate litigation, that change, or, in some cases, reverse, the headline conclusions about economic liability. Roger also raises some new methodological issues (e.g., about currency and temperature units) that deserve a look in the broader climate econometrics literature. That said, the issues with these specific papers should be debated, and the authors should have a chance to respond (which Roger has offered) before people rush to judgment. We are entering an amazing new phase of post-publication peer review with AI. But we should still be diligent, scrutinize, and engage due process for judgment and anything consequential like correction or retraction. Nonetheless, we should also be careful about using damage numbers from studies, which are subject to deep, typically understated, and likely irreducible model uncertainty, to precisely assign hugely consequential practical quantities like liability.

"Trouble comes, instead, through other channels: when professors rotate back into academia and embed their research within a political project, no matter how modest or mainstream; when they censor certain findings because of the problems they’ll generate for their chosen cause; when they refuse to ask certain questions for fear of upsetting political allies or pleasing enemies; when they evaluate the benefits of a policy intervention without ever considering its costs, or costs without considering benefits, lest they dignify the objections of political opponents; when they go out of their way to valorize preferred groups while reflexively ascribing malign intent and moral depravity to those in positions of power and privilege; when they selectively recognize the agency, culpability, or mistakes of a certain population according to how its members figure in a larger political project; when they profess that their research serves—not distantly or abstractly, but quite directly—an activist agenda to eliminate injustices, right wrongs, recover heritages, glorify gods, or uphold some particular understanding of the public good." Spot on.

This is so insightful. Bring it on . . .
People who have been in research fields develop a felt sense that most "research" (in almost any field that isn't exactingly technical) is research theater, and many superstar careers enjoy star status not because of a unique connection to the truth but because of a unique connection with an audience. No one really has the time or stature to, from a position of objectivity and trust, bring popular researchers to heel. But it will get increasingly hard to hide from serious critique. The machines can do critique now, at the level of depth and rigor previously only possible for the academically deranged. We're going to have to revise a lot of what we "know" about the world that isn't really knowledge but is actually just received popular consensus - like floating voltages without grounding wires. The grounding wires are coming.

Before Trump, higher oil/gas prices (and less use) fulfilled climate goals. All this is now forgotten as higher gas/energy costs are used as political cudgel against Trump. Politics trumps policy every time realclearpolitics.com/articl…

Here are the 7 key points from my latest article on the climate attribution cabal. Law professors and climate activists enrich themselves on funding from foundations and the litigation industry and in return try to deliver evidence to sue the oil industry. thefirebreak.org/p/the-envir…

2nd rate minds attempting to defend their politics, careers and funding by cancelling and smearing anyone that disagrees with their preferred narrative and manufactured "consensus"
Replying to @curryja
In climate science, questioning or critiquing a climate science finding is now treated as personal attacks on the researcher. Why is that?

I read Unelected, highly recommend. While I expected the NGO stuff, new media, data monkery, I did NOT expect a serious treatise on political philosophy/history for the past several centuries. This is the book the moment needs.
📚🚨 The book UNELECTED is finally out - order it today if you haven't! 🇺🇸 There'll be more Democracy Files drops today - but as it happens, today is launch day for my book UNELECTED. It is a coincidence that I stumbled into an archive of these ex-USAID officials less than a week before the book's release. The UNELECTED is about how and why a massive global network of NGOs came to dominate our everyday American policies. And crucially, UNELECTED ends in a whitepill that shows us the way out of this mess. UNELECTED is a joint collaboration between @JoshuaLisec and myself. I started this effort because my own doxxing happened during the Tesla Takedown protests, while I was in the process of being recruited by DOGE. DOGE employees were having their life made miserable, and I had to take my own children and flee out of state. While researching who organized and financed the protests, I noticed all the backers were all about democracy. Democratic resilence, strengthening democracy, protecting democracy. I was like ... "wait, why are democracy groups behind this?" DOGE was cutting silly DEI foreign aid awards, it wasn't overturning any elections. What I came to find was shocking - these silly USAID awards added up to a global regime change machine. "Democracy" has nothing to do with elections. "Democracy," to them, means diffused governance outside of the three branches of our Constitutional Republic via private citizens in the form of NGOs. The network started assembling over a hundred years ago with the founding of Carnegie Endowment for International Peace, and has snowballed into a machinery worth trillions of dollars that has sucked taxpayer money, philanthropic money, union dues. That became UNELECTED. You've been reading about the coup the past couple of days. UNELECTED shows how and why the coup came to be. I'm so lucky to have met wonderful people throughout this journey - @petermarocco, "Big Balls" @as400495 , and countless others who sacrificed so much more to right our country. Vote straight Republican on November 3rd, and buy UNELECTED.

My understanding of multidecadal natural internal variability was relatively naive in 2006. Since then I've done substantial research on this. Also the global hurricane data set isn't useful prior to 1980. @RyanWeather 's analysis on this is the best available IMO.

Michael, thank you for these comments!

Judith Curry is one of the most important heroes of intellectual integrity of the past 20 years. I began following her when she was celebrated by the mainstream establishment while commenting on technical climate blogs. She was invariably fair minded and balanced in her replies and consideration of evidence. Her own blog, started later, has some of the most thoughtful commentary on the challenges of climate science and climate policy. Her book is the single best overview of the challenges inherent in both.
