Folks, I am really appreciative of people who have followed me and added me to their starter packs.

I post about climate science, energy system transition, and related issues.

I try to restrain myself to information and questions, and try to avoid unseemly opining in public.

The Democrats should start every interaction with journalists or Republicans with two questions:

1. Will Trump have a brain scan by a respected third-party to document his dementia (or lack thereof)?

2. Why is Trump so focused on preventing the release of the Epstein files?

Trump: "We call them the water drugs. The drugs that come in through water. They're not coming. There are no boats anymore. Frankly, there are no fishing boats. There are no boats out there period, if you want to know the truth. Does anybody go fishing anymore?"

Looks like CNN has gone the way of The Washington Post.

Democratic politicians need to get some training on how to deal with witnesses who don't answer uncomfortable questions and use them instead as an opportunity to go on the attack.

Pam Bondi may be a terrible person but she is skilled at getting in her sound bites and opposition research quips.

It's a pretty big deal that the NYC Bar Association--one of the most prominent and respected bar associations in the country--is accusing the President of ordering the "unlawful summary execution," i.e. murder--of civilians in violation of US and international law. www.nycbar.org/press-releas...

Metrics are tools.

The primary question about a tool is whether it is useful in helping achieving our goals.

While science goes into developing metrics, the choice of what metrics to use depends on what your goals are.

The choice of metrics cannot be used to set overall goals.

““They dragged little Greta [Thunberg] by her hair before our eyes, beat her, and forced her to kiss the Israeli flag. They did everything imaginable to her, as a warning to others,” the Turkish activist ErsinÇelik, a participant in the Sumud flotilla, told Anadolu news agency.”+

You mean the movement that is trying to conserve American democratic principles and institutions, or were you talking about the Republicans?

I think we have found out who the real conservatives are and who was just after power and money.

Now, it is largely the Democrats and a few old-school conservative organizations that are trying to conserve traditional American values and institutions.

It is interesting to see how horse fodder and food was as much a part of our energy mix (20%) in 1820 as coal is today. In 1920 coal was up at 70%. Note these are percentages not quantities.

“No self-respecting university could ever accept something like this,” said Lee Bollinger, a First Amendment scholar and former Columbia University president. “Trying to protect conservative ideas against being ‘belittled’ — that’s about as violative of the First Amendment interests as you can get.”

Totally unacceptable that Speaker Johnson won’t swear in Adelita Grijalva immediately.

He refused to swear her in on Tuesday, and now he's refusing to swear her in tomorrow, though she is in Washington and stands ready.

Important to remember that stories about children killed by vaccine-preventable diseases when they're too young to be vaccinated are, beneath that, stories about the loss of herd immunity.

This baby caught whooping cough from somebody. That somebody was probably old enough to be vaccinated.

“A lot of times, you know, babies don’t cough; they just stop breathing,” warned Mississippi State Health Officer Dr. Dan Edney as he discussed Mississippi's first infant death from whooping cough in 13 years.

"Johnson said he was left tied up outside the building for nearly three hours.

'I asked [agents] why they were holding me if I was an American citizen, and they said I had to wait until they looked me up. I asked if they had a warrant and I asked for a lawyer. They never brought one.'"

We need a bigger national spotlight on this building raid, fam. Agents dropped from helicopters onto the roof. Citizens and non-citizens alike were dragged from their homes in the night. People who weren't kidnapped during the raid had their belongings seized after the fact. This is madness.

"Jones, 27, is among the residents left at 7500 S. South Shore Drive who are trying to piece together what remains after an early morning, high-powered federal immigration raid led to the arrests of dozens of their neighbors at their South Shore apartment building."

Many equate uncertainty with inaction, whereas uncertainty equals risk that, in many cases, should motivate action.

[Until Bluesky gives an edit feature, I should reread my post more carefully before posting.]

Agreed.

The person who is overconfident in their predictive skill gets listened to more than the person who is cognizant of the deeply uncertain condition in which we find ourselves.
