“In this single moment, we got more visual evidence of Trump’s absence of compassion, indeed the indifference to the suffering of another human…What a tragedy that at a time of grave and great challenges a man like this occupies our White House.”

Electrify 50% of your industry, save €250bn/year on fossil fuel imports.¹ Relatedly: the EU sends €380bn/year to autocratic regimes for its fossil fuel addiction. ¹

Happy Mamdani Day, NYC! Checking out socialist Vienna tonight, the cathedral does seem to have a red hue. But the trains run on time, housing is plentiful, and the CEO of the local gas utility is working to get Viennese off gas entirely by 2040, induction stoves, geothermal heat pumps and all.

Tom Hanks explains to Stephen Colbert why he masks on the subway: "I'm doing a play right now so I cannot get sick... I've had COVID enough in my life, I don't need to do that again. So I'm wearing this for health reasons." Thank you Tom! Masks are still a key part of public health.

New York's direct climate impact comes from two sources: 70% is buildings, 30% cars. For buildings, we've had the right laws in place for a while: especially Local Law 97, with -40% CO₂ by 2030

Trumpian climate moves are bad for US competitiveness, that's for sure. But global CO₂ is mostly a function of climate tech deployment trajectories, and the US has sadly little to say there, which leads immediately back to point 1.

And so it begins, Musk's Grokipedia is scraping Wikipedia and re-writing things in Musk's image. The entry for climate change? Let's just say the Wikipedia entry has neither an "Economic and Policy Critiques" section, nor one on the "Role of Media and Advocacy" that accuses both of bias.

A 14-word replacement for most op-eds, substacks, etc about this moment. The GOP could stop ALL of this, right now—if a handful of Sens or Reps could step outside the cult. It would take four in the Senate, four (maybe five) in the House, to change history. Until then, they're all to blame.
