The most important thing is not to fall for people hand waving about how AI will definitely help to fix climate change so we should develop it as fast as possible. Honestly, nobody knows. It could help a lot. It could also hinder solutions.

This is a good thread, and it highlights an important point. Using averages for oil and gas emissions hides huge variation, and big progress can be made by tackling the tails of the distributions.
This is well worth a read. But it's premised on a notion that gas is still good in the short term, everywhere. By Zeke's own analysis elsewhere, US electricity emissions haven't gone down at all since the dawn of frack boom. We also know that right now, methane leaks in the Permian average 9%.
In the era of affordability politics, making clean energy cheaper may be a more viable emissions mitigation strategy than making dirty energy more expensive. My latest over at The Climate Brink digs into the debate:

one thing i love about parenting is how trying to teach my kid things forces me to learn them in a different way
when she is getting mad at someone over something silly, we talk about:
-why do you think this is impacting you?
-are they worth giving your energy to?
-what is the ideal outcome?

i realized one day that if someone has upset me, they stole a little bit from me.
if i am not invested in having a relationship with them, every extra second I give them is one i lose.
no one is changing their mind on here. when you dogpile folks you reinforce what you’re mad about.

My one real comment on the Jan 6 5 yr anniversary is that it was carried out by rich people. The poor hick stereotype is incorrect. It was rich people, suburban millionaires and their backers. We know this from who was arrested. It cost money to go to DC, stay at fancy hotels, fund this, etc.
Scores of now-pardoned Jan. 6 insurrectionists will gather from 11:45am for a march to the Capitol starting at the Ellipse.
One insurrectionist who says he's attending: Enrique Tarrio, who was sentenced to prison until 2045 until Trump intervened.

28 San Francisco homicides in 2025 - this is being reported incorrectly as the lowest number since 1954 - a year which actually saw significantly more homicides according to the OSU CJR database. My back of the envelope is that per capita it is the lowest number ever.
In 2025, the number of people killed in Baltimore had plummeted to a nearly 50-year low of 133 deaths, said Mayor Brandon Scott, marking the third straight year of steep declines in the homicide rate and a nearly 60 percent decrease since 2021.

Why cancer can come back years later — and how to stop it
Researchers are targeting dormant tumour cells that might explain why some cancers reappear long after successful treatment.
