If you’d like to hear Ben Santer talking about this “arc of history” from the IPCC’s discernible influence finding 30 years ago to the present, then his talk at CRU’s 50th anniversary is a nice intro to climate fingerprinting youtu.be/ZinW-m2GDvU?...

Thank you Matthew for sharing your story

I was a medical student in the early 90s & saw way too many young MSM in their 30s die of AIDS (& I volunteered as a Terrence Higgins Trust “buddy”)

The development of antiretroviral drug treatment is surely is one of the greatest ever medical achievements👏

Today is World AIDS Day.

Don’t forget those who died.

Senator Kelly is correct.

Plus a Public Service Announcement:

KEY section of Department of Defense's Law of War Manual is 18.3.2.1.

The VERY rule on the "requirement" to refuse illegal orders gives as its paradigmatic example of what is "clearly illegal:
"orders to fire upon the shipwrecked."

Just like the tobacco companies!

A reminder, in light of that NYT story today, about skill and spread across climate analytics providers:

Getting good climate info in the hands of individuals would be highly valuable. Just not convinced we're actually there yet.

I love cheese, but yes - in fairness they should pay too (in proportion to their contribution).

Some more thoughts on the Zillow/FirstStreet/Realtors story.

Ben Santer writes. It's worth reading.

New idea for a climate change lawsuit:

The realtors sue the fossil fuel companies for lost commission on sales that are literally underwater...

Look you just have to make the cool weird shit that excites you. You must. In this world besieged by bland, scrubbed boring, computer slop, you must. Make the thing you’re embarrassed to make, the thing that feels “too much” because otherwise we get drowned in a sea of cowardly work made by a button

I’m not sure. Almost everyone thinks that they’ll be the ones to sell just before it all goes south. They can’t all be right of course…

Rabbiatu is a nurse who worked during COVID, had been in the U.S. 30 years. A judge ordered that she could not be sent back to Sierra Leone for her safety, for fear of torture (!). So our evil regime sent her to Ghana (in shackles), and Ghana dragged her back to Sierra Leone.

But this all needs a much more inclusive and deep national conversation as the increasing risks become more obvious. Clearly this is unlikely to happen right now for… reasons. But it would still be a good idea!

Brokers always gain from higher prices (so their motivation is clear), but buyers should really benefit from better information (or indeed any information about risks), and so a responsible industry (ha!) would be perhaps a bit more nuanced. 🤷

In the absence of any consensus or federal action to update hazards mapping, this kind of retail providing of info is the only way to bring this info into the system, but this effectively means that it is current homeowners who will (partially) bear the cost (and they aren’t happy to do so).

…since risks are increasing there is an overall loss of value (relative to the mean) and it’s a real ethical and social dilemma who should be on the hook for that: The current home owner? The future one? Insurance companies? The state? The feds? The fossil fuel companies?

There are real concerns about how accurate the estimates of risk are, but that is inevitable since you are projecting out to the future in a non-stationary system. Having said that, the First Street guidance only claims to be indicative. Hiding these indicators does a disservice to the buyers. But…

This is the point:

“Displaying the probability of a specific home flooding this year or within the next five years can have a significant impact on the perceived desirability of that property,” said Art Carter [CRLS CEO]

Trump Frees Fraudster Just Days Into Seven-Year Prison Sentence

"President Trump has set free a private equity executive who had served less than two weeks of a seven-year sentence for his role in what prosecutors described as a $1.6 billion scheme that defrauded thousands of victims."

This is a legitimate scientific revolution in meteorology.

Also, to be clear, these models are not the AI LLMs that most people are familiar with. They are machine learning algorithms trained on observations (actually reanalysis).

I loved this guy’s stuff. From playing the Real Inspector Hound at school, Arcadia when I was studying dynamical systems, R&G are dead, and, lastly, Leopoldstadt (which really did a number on me). 😢

Pentium chip would like to have a word…

The legal, media, and academic institutions capitulating to an authoritarian ordering payments for favorable treatment are damning themselves to irrelevance. They are destroying their institutions. They will be — and should be — shunned for failing in their most basic purposes for existing.

Goes for substacks as well...

Imagine if all the hundreds of billions of dollars being pumped into AI was given instead to artists, writers, musicians. If/when the AI bubble bursts, everything will get crappier, but you give that money to artists: no bubble, just a world more humane and human in a million little ways.

It is unfathomable that the USG lawyers would sign off on a no-survivors boat strike (no get of jail free card).

There's clear precedent dating back to World War II trial of Germans for that very act, which lawyers know well.

What approach are you taking to the code? OpenACC, or translation to a DSL or Julia or Jax or something else?

Wow. BBC journalists are now not even allowed to report the censored line from my Reith Lecture, that Trump is “the most openly corrupt president in American history.”

You can hear how carefully they’re forced to tiptoe around it. So chilling...
