AI1/ Emergent behaviors of “scheming” and even outright deception were just covered by The Economist:

AI models can learn to conceal information from their users
This makes it harder to ensure that they remain transparent

About *a third* of global fossil fuel CO2 emissions emitted during the Industrial age have occurred in roughly the last 17 years. The previous third was emitted over a period of roughly 26 years. The first third was emitted over a period of about 131 years.

"I would hope they’ll just say no to an ultimatum disguised as a compact. I would hope they recognize that it would quash academic freedom, chill free-wheeling classroom discussions and discourage the best and the brightest from wanting to teach or do research in Texas. I’m not optimistic. "
We’re UT, not TU. Just say no to Trump's ultimatum. | Opinion
Trump is dangling extra funding for universities that agree to his Compact for Academic Excellence. University of Texas risks becoming the University of Trump.

Picture how big the Hoover Dam is. An absolute unit. The Hoover Dam has a power capacity of 2 gigawatts (GW).

The solar farm that the Admin just cancelled could have produces 6.2 GW of power. That's more than 3 Hoover Dams.

This is nothing more than a continuation of the president’s desperate weaponization of our justice system.

I am not fearful — I am fearless.

We will fight these baseless charges aggressively, and my office will continue to fiercely protect New Yorkers and their rights..

The case against Tish James is even weaker than the case against James Comey. A box got checked on a form saying that a property she was helping her niece buy was going to be James' primary residence. But James sent an email to the bank saying: This will not be my primary residence.

Sent Steve a letter:
Dear Steve,
 
I hope you are well.
 
In your Monday WSJ column, you criticize the National Academies for not reviewing your DOE Climate Working Group report. To my knowledge, the Academies have never offered an unrequested review of a government scientific report. I am sure they would have been happy to review your report if DOE had asked them to. Though DOE chose not to do so, under Information Quality Act guidelines, an independent peer review (like that the Academies often conducts for the federal government) is required for it to be legal to use the report in rule making. (See Section III in  70 FR 2664)
 
In your Monday column, you do not mention that — seeing no evidence that your report had been the subject of any meaningful independent peer review — more than 85 experts volunteered our time in the month of August to review your report. The approximately 450-page compendium of comments, co-edited by Andrew Dessler and me, evaluates each portion of your report. In case you have not seen it, you can find the expert review here: https://doi.org/10.22541/essoar.175745244.41950365/v2
 
Your column recapitulates a number of the errors and misrepresentations in the DOE report, which are evaluated in detail in the expert review.
 
For example, you state that US heat waves “aren’t more common in recent decades than they were in the decades around 1900”.
 
As we write in the expert review, the DOE report  “highlights the Dust Bowl period of the 1930s as a time of unusually hot temperatures in the United States.” However, “over such a small area [as the contiguous US], natural variability can play a large but temporary role. The Dust Bowl was indeed an exceptional event, although unrelated to greenhouse-gas forcing, and the decadal climate conditions that drove the Dust Bowl are not occurring today…. If you take out the 1930s, there are clear trends [in the contiguous US] towards more extreme temperatures due almost certainly to radiative forcing.” Further, “if one examines a larger region, where the Dust Bowl’s influence is diluted, then there is an obvious, strong trend towards more extreme temperatures.”
 
You also introduce in your column some errors that are not in the DOE report. For example, the DOE report addresses global-mean sea-level rise only in passing, focusing instead on specific US tide-gauge records. In your column, you claim that a global sea-level acceleration comparable to the current one occurred in the 1930s, a claim we discussed before about eight years ago.
 
In 2017, I told you, based on our analysis in Hay et al. (2015), that the rate of global-mean sea-level rise in the 21st century was likely faster than during its previous high in the 1930s-1940s (notably, also a period of significant global-mean warming, preceding the slower sea level rise and lull of warming in the 1950s-1970s). At the time, global-mean sea-level acceleration had already been sustained for close to five decades, compared to about two decades in the 1920s and 1930s.
 
The evidence in the last eight years has only gotten stronger. We are now in an approximately 60-year period of nearly unbroken global-mean sea-level acceleration, and the current rate of rise revealed by both satellite data and tide-gauge analyses — exceeding 4 mm/yr — is unequivocally higher than at any previous time revealed by tide-gauge reconstructions or satellite data (see, for example, Dangendorf et al., 2024; Figure 8 therein reproduced below). (Note that this finding is supported by Frederikse et al., 2020, a key figure from which is reproduced in a simplified format in your book Unsettled.)
 
Further, combining tide-gauge and geological data shows that there has been a sustained acceleration in the long-term rates of rise since the mid-nineteenth century. Modern rates of 60-year-average global-mean sea level rise exceeded earlier Common Era rates by the 1860s, and the current rate of global-mean sea level rise virtually certain to be higher than any century-scale period in the last three millennia (Kemp et al 2018, Walker et al 2022; Figure 1 of the latter reproduced below).

Furthermore, I don’t think either of us contest the fact that global-mean surface temperature is substantially higher today than in the 1930s and 1940s. It would, indeed, then be quite physically surprising if the rate of global-mean sea level rise were also not substantially higher.
 
It would be tedious for both of us to respond further to the errors in your column, but I point you again to the expert review of your report: https://doi.org/10.22541/essoar.175745244.41950365/v2
 
I encourage you not to continue to recapitulate the errors in the DOE report while ignoring the readily available evaluations in the expert review.
 
Best,
Bob

You've probably heard how a high percentage of #Nobel laureates are immigrants. The US in particular has benefited from the influx of bright minds.

@jennaahart.bsky.social ran the data for this century's Nobel prizewinners — and shows more than 30% immigrated. 🧪

2/ On the other hand, the old Bell System actually had contingency plans for all sorts of disasters and could apply USA-scale resources when needed… sort of like the way FEMA is supposed to work.

1/ I recall weird parallel from my old Bell Labs days. Older gear tended to fail often enough in same ways that telco repair people stayed in practice fixing problems. Of course we kept improving reliability with new tech… which meant that failures were far less frequent (good!) but also unfamiliar.

The MMR shot is safe and effective, and there is no credible evidence otherwise.

Breaking MMR into three shots means 3x more copays at the doctor’s office, 3x more hours of missed work, 3x more bummed out kiddos, and probably more than 3x as many kids who aren’t fully vaccinated.

The historically volatile Texas grid was entirely stable this summer, despite extreme temperatures. Grid operators never once had to ask Texans to conserve energy or shut off their air conditioners.

Why? Solar & batteries. Want a stable grid? Try solar & batteries.
Solar and batteries had a record-setting, grid-stabilizing summer in…
Solar has set 17 power generation records in Texas so far this year, shoring up the grid alongside batteries as some gas plant developers step back.
