“the constitution forbids race conscious remedies” would be news to the people who wrote the 13th, 14th and 15th amendments

Trump has killed a total of 27 people in targeted strikes of vessels in the Caribbean Sea.

@jahimes.bsky.social and I discussed this very issue yesterday right before Trump blew up yet another boat killing all 6 aboard.

As Felon Trump calls Democrats “terrorists,” he has also unilaterally declared cartels “designated terrorist organizations.”

@jahimes.bsky.social wants answers from the Admin about what’s going on & why Trump thinks he’s legally justified to do extrajudicial killings.

One of my only remaining joys is that every single time Amy Coney Barrett makes a stupid argument, Ketanji Brown Jackson gets a chance to follow up and illustrate her stupidity.
And this will happen again, and again, for the rest of Barrett's life.

Driving just 100 km with a car using biofuels would require close to 3,000 litres of water due to the huge amount of water they require.

It would only take about 20 litres to produce solar electricity to drive an EV that same distance.

City of Manhattan Beach owns the land under the country club & leases it to the MB Country Club. In a rejected draft Housing Element, the city said that the site would be developed into 100% low income housing.

It feels like the political overton window has shifted far to the Right because the wealth class controls our media and owns our politicians.

Meanwhile, the vast, vast majority of people belong to what would now be portrayed as “the extreme Left.”

It’s a perception game and narrative control.

I’ve got a short piece up in The Conversation on the catastrophic flooding in Southwest Alaska from ex-typhoon Halong and the challenges of recovery work. #akwx #ExtremeWeather #Alaska #AlaskaSky

Typhoon leaves flooded Alaska villages facing a storm recovery far tougher than most Americans will ever experience

‘As the storm approached Alaska, everything went sideways,’ leaving people no time to evacuate and little time to prepare. An Alaska meteorologist explains what happened and the challenges ahead.

Completely agree with the “should” of this, but the problem is that dead and disappeared people never get their day in court. And even lots of people who do get their day in court never get justice, for reasons we all understand.

If men with guns and masks tried to pull me out of my car, I'd fight back. Courts should reject any claims by the government that this is aggression by the person being detained, resisting arrest, or that they're a flight risk.

Farmers grow what they grow because of farm policy.

We don’t need all the soy and corn that we grow, but those are the commodities that receive subsidies and markets.

If we want something better, if we want to heal the Earth and grow food, now is the time to do it.

And this:
92% of the growth in the entire country this year has been data centers. And some of that is "circular deals" that dont involve actual money
